Just replaced Mobo, now Comp doesn't turn on

Q: Just replaced Mobo, now Comp doesn't turn on

I just replaced my old board, processor, and memory in my backup comp with an MSI K8T Neo-V board, AMD Athlon 3800, and 1gb memory. I got it all set up, and powered it on, but the fans kicked for a sec, and the power LED flashed on, but went off almost instantly. I re-seated everything, and unplugged all unnecessary devices (HDD's, etc), and it still did the same thing. I'm thinking it might be power supply, but it worked immediately before the upgrade. Any thoughts?

Preferred Solution: Just replaced Mobo, now Comp doesn't turn on

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Do you have the 4-pin molex connector connected from the power supply to the plug near the processor on the motherboard?

I posted in these forums about 3 weeks ago becuase my computer wasn't powering on. It just flickered when I hit the power button and then died. only the led fans lit up, for a second, nothing started spinning.

I've tried EVERYTHING with my old mobo and psu, including shorting out the pins, resetting cmos, unplugging HDD, etc, I'm pretty sure i did literally everything to try and fix it.

I bought a new mobo (p5n-e) and PSU (rosewill 550w) to replace my previous components (p5b and FSP 450w) first I got the new mobo and plugged it into my old PSU, that didn't work, so I figured either my PSU and my mobo were both fried, or my PSU was fried, so i got a new Mobo



A:HELP! I've replaced my mobo and PSU and my computer STILL! doesn't boot

Perhaps the CPU is the next potential culprit.

Well my computer doesn't turn on anymore. It was working fine and then the power cord of the surge got unplugged from the outlet. Needless to say the comp wont turn on anymore. I was wondering if its the psu or the mobo that has messed up. When I plug in the comp the steady power light turns on, on the mobo which i assume it means it receiving some type of power. But when I press the power button the led lights of comp flash on and then turn back off. So does anybody know if its the psu or the mobo that is damaged?

A:Comp Wont Turn ON is it the PSU or the Mobo

Probably Power Supply (hard to say really)

Just for a quick option:

Remove the power cord
Hold the On button in for 30 secs (releasing all internal voltage)
Put the power cord back in (securely)
Turn on (I hope)

Hi there! I've a problem with my computer. After I'd updated the BIOS (my mobo: Gigabyte GA-P35-S3) the machine stopped turning off. I mean, the fans still worked, the monitor stopped responding, the led on chassis was on. But someone helped me on IRC - told me what to change in the settings and it worked. Unfortunately after I'd updated the BIOS again I deleted the backup and it doesn't work. In Gigabyte they said to flash the BIOS to the new beta, and when it didn't help - to change the mobo in the shop. Can someone please help me?

I have the ecs k7s5a motherboard with a amd xp 2000. Everything is connected but when i hit the power button the cpu fan turns for 3 seconds and stops. Thats it, nothing else happens.
Does anyone know whats going on?

A:[SOLVED] my comp doesn't turn on

are you just putting the computer together or has it worked before?
if your just now setting it up it could the motherboard shorting out. like if one of the mounting screws for the motherboard is touching something on the board it could cause it to short out. try and see if you can remove the board from the case so that its not touching anything metal and see if it will boot up.

When i went to bed my computer was working fine. but when i woke up (8 hours later or so), When i press the power button nothing happens, not even a choke to try and start up. The weid thing is that when i turn on the rear power switch, the motherboard green LED is on. So im not sure if this is consistent with PSU failure? I would have that PSU failure for sure but now im not certain.
i have tried:
Using a known good power socket.
switching the power and reset buttons on the motherboard to see if it was the siwtch
Short circuiting the on switch on the motherboard.
When i unplug the motherboard power cable from PSU, the green LED turns off, when i plug it back in it turns back on.

Does anyone know if its a PSU problem or somethign easier? Because it's really throwing me off. I think i have to be getting power, since the mobo LED is on.

A:Computer doesn't turn on, but mobo LED light on

Hello and welcome to techspot.

I'm not good at all when it comes to this case, but coincidentally, i have the same issue last year.So i decided to write some possible reasons :
1. PSU failure (+12V A rail is too low)
2. Capacitors leaked
3. Heatsink and thermal gel not installed properly
4. Few drives problem such as HDD or optical drive
5. short circuited cables inside the case.

So far, when this problem happens to me, i could not turn on the PC whenever the HDD is attached. But when i unattach it, the computer would on.
Or another issue, i have a fan in the case which i have not installed yet. Accidentally, when i move it with a pincer to the correct position, the metal parts of the fan get in contact with the CPU case. Straight after that my computer turned off, BUT the CPU LED is on.

Well, let's find out more about your computer, can you give your system specs here?

I have a HTII 713 luggable PC that will not power on. When this problem first started, you would hit the power switch and the power would "stutter" but not come on or make it to post. I upgraded the power supply. It originally had a 460W PSU and I upgraded to an Antec 650W PSU hoping that would cure my ills. Still displaying the same symptoms. I got an exact replacement Intel motherboard (Intel DP965LT) and swapped it out.

Now I get power lights, but no fans, or hard drives spinning up. When I hit the power, the case fans and PSU fan will move just a tick but not spin and this only happens the first time I hit the power switch. I have to wait about a minute or so and try again to get this to even do this much. I've triple checked the power connections and mobo connections.

Any ideas?

I replaced the mobo on my Dell 5510. Purchased from Dell. Sticker on mobo says BIOS ver A05. About every other day I get blue screen and physical dump of memory. My system info says my BIOS ver is A07. How do I go about changing BIOS? Is it as simple as pulling battery for 15 seconds? Some have offered this suggestion but I get a little worried at "friends" advice.

A:Replaced MOBO on Dell 5510 BIOS sticker on MOBO says A05, system in still has BIOS of A07

Removing the battery won't change the BIOS version. You need to download the version you require from the Dell site. From Windows you "flash" the BIOS. Take your time preparing for this. If anything goes wrong you will wreck your motherboard.

A:Got my Mobo Replaced....

Read other 16 answers

Hello. Never even had a chance to get PC online and register and found out my asus mobo was faulty. I did installed OEM W7, however. What consequences, if any, do I know face as a result of swapping out mobo's? (activation wise?) I do plan on wiping the HDD drive and reinstalling windows, unless somebody with experience here recommends "not" to do this. The last thing I want to do, is get this thing up and running, fully loaded with all drivers, programs and the such and then have operating issues because I didn't reformat drive, due to the mobo exchange. Also not sure how MS knows that I changed this device, due to the fact that I was never even online. There is nothing dishonest going on here. Plz advise.

A:OEM W7 and replaced mobo

Technically the OEM license is tied to the machine it is first installed/activated on, and would need to be replaced if the system were changed (and at least according to Microsoft's servers, replacing the motherboard constitutes a new system). However, since you are the owner of the system and this is not royalty OEM (in which case they would have dealt with this via token activation already), you will simply have to call Microsoft to re-activate if it does not do so online, and you will be able to use that license again on the same machine (well, minus the motherboard difference, of course ).

hello everyone.

im new to the site, and new to the hardware side of computers (genuine noob).
my brother in law had an old alienware desktop sat in his garage unused due to some components being fried. i decided to take on the challenge of repairing it for my own use as a gaming machine.
apparently the graphics card died and my bro in law took it to a pc shop and they said something else had fried too.
ive had the pc open and had a little nosey around but everything appears to be ok. started the pc up with everything as it was. sounded as though it ran fine but no picture on the monitor. this would confirm the graphics card being ruined. i tried a different graphics card in the pc and got a message on the monitor about the frequncy being wrong ( i honestly cant remember what it said). any how, going on what my BIL (brother in law) said, i thought replacement mobo and processor.
had a look on ebay and managed to find the exact replacement mobo, cpu, that came with 2 sticks of mem and a graphics card. total cost 22.50.

specs as follows:
MOBO = D865PBZ intel
CPU = pentium 4
mem = is apparently 1GB
graphics card is unknown

this is what i received today in the post. brilliant. so straight to work on replacing the parts. original mobo and cpu out. the replacement ones with mem and graphics card went in. i hooked up all the components incl... 2 x hdd, 1 x cd/dvd drive, and a floppy drive too.
powered the machine up and 2 seconds later it switched off. Gut... Read more

A:Mobo replaced but the PC does not start

There are so many things that can go wrong with this... Make sure the motherboard is not shorting to the case. Did you clean off the old paste and apply thermal paste between the CPU and it's heatsink? Did you attach the power supply 4-pin (12v AUX) connector to the connector near the CPU socket? The 3 long beeps are normal when the memory is not installed, and you must remember to at least install memory in the slot closest to the CPU. The 3 beeps give me hope that the motherboard is okay...

Fortunately, the mobo & mod bay will accept the floppy drive. Unfortunately, it will only accept the DVD Rom drive if I push on it a bit and won't even recognize the cd-rw-dvd drive. It's seems to not want to "click" into place, tho it is locked in.

Hello all. I have just replaced my motherboard. The old mobo was Asus p6x58d-e and the new one is a Asus Sabertooth X58.
Both are a very similare spec with all the same components, network/sound etc.

The problem I am having is when i put my HDD back in the machine it blue screens when booting into windows 7(32 bit).
The error is:
"a clock interrupt was not received on a secondary processor within the allocated time"
I can boot into safe mode only. Can anyone advise if there is something i should be doing to get this to work?

Thanks in advance

Ok ...

I had a puter which either my motherboard or my cpu died on me. So I bought an AthlonXP2400+, Asus A7N8X, and a stick of Kingston RAM to go along with the Western Digital drive that was already in there.

I had to know if it was the chip or the board that died, so I installed the Athlon T-bird 1.33 chip in the board and turned it on. It was posting, but it said "Warning: CPU have been changed!" It wasn't even posting before, so I was happy to even see see it do this. So then I put the new chip in. I booted up and it said the same thing. So I went into BIOS and set everything back to defaults and that stopped. So now, when it posts, it detects the old 1.33 processor speed that I had tested in there (1700+? I think). Then after it posts, I get a stop error and it says A problem has been detected and windows has been shut down to prevent damage. It tells me to check for virii and remove newly installed hdds or hdd contollers and to run checkdisk. It does this when I boot into safe mode also. So in case, I put it on my other computer and ran tests and it was fine. I had an extra hdd that I tried in the new computer and it immediately gives me an error "NTLDR is missing" and tells me to his control +alt +delete to reboot. Im assuming I have all kinds of settings messed up in the BIOS or something. Can anyone shed any light on what is happening to me?

A:Replaced mobo, cpu, ram.. will not boot.. :(

Make sure you switch off the Virus-check in your BIOS, that accesses your HD.

We have an E-Machine computer. It's a T2625 model. It kept turning off on it's own and acting strange, finally it just quit and we replaced the power supply and it worked briefly after the PSU was replaced but then didn't work again. The motherboard did go out with it because we tested it. The motherboard has been discontinued but we found one online that was new and the exact same one that was in it and ordered it because emachines wanted $160 for the replacement kit for the motherboard and now it still doesn't work. You can hear everything running but there is no video output at all. We have tried alot of different things and still nothing. Could the processor and/or RAM be bad too?? Also it currently has an AMD Athlon XP 2600+ (2.13 GHz) processor in it now and for RAM it's got 512 MB DDR (PC2100) in it. If we go ahead and buy a new processor and RAM just to try, how do we find what's compatible for this computer?? Thanks!!

A:Help..Replaced PSU and Mobo and still not working??

What you report is typical of the motherboard failure that impacts more than 50% of the T2625 eMachine computers. The T2625 is one of 14 eMachine computers which has unusually high rates of motherboard failures within two to three years of purchase.
Your only choices will be to replace the motherboard with one from eMachines for $159.95, or to buy a new motherboard of another manufacturer - which will most likely require a store-bought version of Windows... as the exisiting eMachines recovery disc set will only work when it can detect the "tattoo" on the ePROM of an eMachines motherboard.
Usually, your hard drive, memory, modem, and new power supply will work fine with the new motherboard but you will need to check carefully to assure that your CPU will work. There are many deals at many seller websites which include a motherboard and CPU bundle for $50 to $100.
The hard drive will not work without contact with Microsoft to get the product ID registered. Usually Microsoft will tell you that the Windows XP install dies with the motherboard dies, but some people have slickered them into allowing the drive to be moved to a new system.
If it were my decision, I would take this opportunity to buy a new or refurbished computer.
Good luck to you. Let us know how it all turns out.

Hey there, I'm new to this. I purchased a computer from MDG and fried my power supply and motherboard. I found another power supply and peplaced the old one and found an identical biostar m900-m4 mobo and switched that up as well thinking it would just boot as normal. When I started up I get:

Now I have no idea what to do. The Mobo looked to be identical and same model, but I noticed the board was blue instead of green and PCI slots were Orange instead of white but all in all looked the same. Any ideas to avoid paying a hefty sum to take it into a computer shop and dumping a whole whack of money I don't have? Plus I love learning. Any suggestions would be appreciated. Thank you

I've replaced the above, and memtested the ram (which is a few months old). These BSODS are killing me.

FRESH install (did two this last week too, so I made sure not to botch the OS install) of Win7 Pro x64
DDR3 1333 4gb ram
Foxconn G41MXE Mobo
Celeron Sandy Bridge LGA 1155
video card = Geforce 9400GT PCIE

I've attached the necessary docs.


A:Random BSODS, replaced mobo/cpu/psu


Four attached dumps, all from 6/20. The first is a *50 pointing to memory corruption (could be a 3rd party driver, not always directly related to the memory itself). The next two are *1a memory_management culprits, and the final is a *50 page_fault_in_nonpaged_area pointing to the driver peauth.sys, this is the Protected Environment Authentication and Authorization Export Driver. It's a MS driver and is very likely not the culprit, so it's likely your issue is hardware related given the memory corruption and memory management bugchecks and no culprit drivers.

You said you've memtested the RAM, but for how long, and did you use Memtest86+? The + is important. I recommend no less than 6-7 passes, which takes many hours. I generally recommend doing so before work or sleep. 6-7 passes is enough to get through a fair amount of important testing to determine the RAM is stable.

If Memtest yet again comes up clean, I'm going to recommend Driver Verifier, which you can read how to set up here.

My emachine (T2245) mobo got fried. I had to purchase a new mobo ASUS P5LD2-VM DH which I had eventually had installed. The problem comes in during Windows XP(home edition) boot up process. My HD was configured under the old mobo. Now, i understand that in order for my windows to boot up i need to ran wind XP cd, and to use windows' "repair comand". I have tried using windows xp restore cd which was originally supplied with the old mobo and it had not worked. Then i went to a friend a borrowed windows XP cd to try to format my HD. So what i did is that i used a computer to boot up from a CD. After the installation starts it goes through drive installations and after that the message comes up stating that: A problem has been detected and windows has been shut down to prevent damage.....Technical information:
*** Stop: 0x0000007E (0xc0000005,0x8081A343,0xF7A260D4,0xF7A25DD4)

My question is: whether there is something wrong with my HD? or the way i had connected my new mobo? or there is a major problem with my mobo? or there is a compatibility problem since my HD was configured under my old emachines mobo? and what is the best way to get it fixed?

Thank you

Having this problem ever since my pc got taken in for repair.

they changed the mobo from an MSI to gigabyte and i have to say im not very happy.

the new gigabyte board will only let me overclock my e6750 to 2.7ghz? anymore and the system reboots on start up and places my speeds back to stock.

other than that i get stuttering in games now e.g bf2 and cod4.

anyway to prevent stutter? i've done all the usual procedurs such as defrag and various optimizations.

also my internet has lost some speed which i can not understand either since the new board was put in, especially when it comes to gaming. pings are high when browsing for games which never used to happen before.

the new board is GA-G33M-SL2.

- Win Vista
- Nvidia 8600GT

I am normally very good at fixing my computer but this problem has me stumped. My custom built computer which has worked for a couple of years now is having a major problem. I have tried several mice, including replacing the one that has worked for a good year with two separate USB mice, one wired, one wireless. I also replaced the keyboard which was getting a bit old with a new wired USB keyboard. The problem persisted so I eventually gave up and replaced the Motherboard. Initially the mouse and keyboard worked without a problem but then I moved back to university where the problem first started and it started again. What is more strange about this problem is that the keyboard works before windows starts, but not completely. I have gone into BIOS but there is an odd problem where several of the keys on the keyboard do not work, including the up key and f10, which makes saving any changes impossible. I cannot work out a way to fix this, unfortunately I do not have any remote desktop software installed on my desktop so I cannot fix it like that. MY last bet is to reinstall windows, although I'm not sure if that would fix it as the keyboard is acting up in BIOS. I have tried unplugging the desktop and holding the power button for 10 seconds, to no avail. If anyone could help I would be very grateful, thanks.

A:USB Mice and USB Keyboards not working, have replaced MoBo

Maybe clear the CMOS settings. Your motherboard either has a jumper or switch to clear CMOS settings. Remember to properly shut down and power down your system beforehand. Try that and post back.

Last night i took out my MicroATX mobo out of my PC (it DID NOT have an AGP slot) and I replaced it with an almost identical MicroATX mobo (the new mobo DID have an AGP 4x Slot...I mainly want it so i can get a Radeon 9800XT this chrismas...lol).
Anyways, I got the motherboard (the new one) out of another my mom's system (which she upgraded my recently). so i know that the mobo is fine. I got everythin set up in the Bios and it recognizes the AGP videocard (GeForce 2 GTS Pro), the memery, CD drives, floppy, and CPU. (i also has 3 fans in this box to cool it down... so it's not over heating).

I go to boot windows and i get this STOP error:

STOP: 0x0000007B (0xF894c640, 0xc0000034, 0x00000000, 0x00000000)

And i havn't gotten past that point.

I've also figured that i should re-install windows from scratch (re-partition) but i can't seem to access the Boot menu to selet the IDE CD-Rom device.

it only seems to be recognizing my Secondary Slave; not Secondary Master (I have a DVD-Rom and a CD-RW)

I can't seem to get to a boot menu to manually select to boot from the IDE device.

I have to press F2 to get to my CMOS menu.

I can't get into my windows XP setup CD
I want to know know how to Fix this problem as it's a BIG problem to me. I want to get my computer to work. anything that you guys can do would help. thanks.

I also bought a refurbished motherboard stock for the computer, and put it in. The computer turns on , fans on the motherboard spin, but the monitor displays nothing. The power supply fan is NOT spinning. Is this an indicator that the Power supply is bad? Power on the motherboard panel ( USB ports and etc., ) the components will "flicker" and then not work period, unless i tamper with the wire , unplug it replug it in. then it will flicker again. CDROM pulls in and out. Wiring all done correctly. Could this also be a processor problem? I am so aggravated

The kicker: Dell has no access to the key b/c it's soldered onto the mobo they say. Now they claim a mobo failure, since it's out of warranty, and will send a tech out for $399 to replace it. I've never heard of any company soldering the win key to anything. Is this true or false? Since there is no OS, is there any way to get they key or am I dead in the water?

First - a couple things out of the way... 1) I am an A+ certified technician, and have replaced probably a dozen different laptop screens over the years.2) The computer was working just fine, except the left 1/3 of the display was completely black - and HP felt that it wasn't a coverable repair from their Care Pack support. So I purchased a replacement screen (matching model) and installed it. However, when I went to start it - nothing happened (the little light on the power button didn't come one).  The little light by the power plug in on the notebook does light up. While I'm pretty careful about everything, obviously, I did something that caused the problem.  The problem is tracking down what is now the issue. I'm assuming that there would only be certain possible simple solutions that this could cause (plugged a wire in backwards or something of that ilk) - and I'm also assuming that other possible issues wouldn't stop the computer from booting (like if the hard drive was not seeded properly, or the wireless adapters weren't plugged in right - I assume the computer would still boot, just giving you error messages or something along those lines). Same thing with the display - I would assume that if the display was bad or I didn't plug something in right - it would still power on, but just sit with an unseen error or something like that. So please inform me of what my possible solution tracks are! Thanks.

My monitor goes black and I am forced to reboot. After rebooting I get a blue screen prompt telling me that i've recovered from a BSOD. I've been monitoring them since October.

In October, I RMA'd my graphics card. Oct 27. You can see that after I got a new GPU, my BSOD's halted... so obviously its the GPU right? if you look at my BSOD dumps the last one is OCT 27, new gpu, and i don't get one until Feb 7.

So on Feb 7 I call up eVGA again and say, ok so my GPU is bad again and I wonder if its something im doing to kill them.

So I am going to get a second RMA and the tech tells me that they received my first card and they ran it for over a hour in a diagnostic app and didn't have a single problem... aka my card was fine...

so i explain my BSOD issues and the tech tells me that it may be a voltage issue and that it may be my power supply... soooooooooo

I goto Tiger Direct down the street and buy a "whatever i can get" thats over 1000 watts supply because I have a 850 watt PSU and obviously its not enough power so i go big... and guess what... My last BSOD dump before the PSU is 3/18 March 18. So new PSU and I don't get a single BSOD until 6/14/2014.

So I have attached "All" of my dumps and all my info with the issues.

My problem is... if its "not" my GPU, why did getting a new one give me no BSOD for 3 months.

my problem is... if its "not" my PSU why did getting a new one march 18 let my PC run ti... Read more

A:BSOD 0x116 (stop error) Replaced GPU, replaced RAM, replaced PSU

Hi Zuriel.

I read your OP. I would suggest you to have an open mind; and dont decide that it is not it. Because during troubleshooting you have to get everything tested.

The BSOD is a stop 0x116. That is an error from the part of the display environment. That means ....
The GPU itself
The display driver
The system temps and dust allocation inside the computer
The hardware parts like GPU fans
Overclocking failure
And etc. I would suggest you to go through a thorough troubleshooting, whatever may be the idea you may have about those.

Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Check if the Power Supply Unit (PSU, 850 watts you said) supplying adequate power to the computer or not.

Hi guys,

I just replaced a bad T61 power jack ( I'm sure it must've been bad since two of the wire connections came loose from the jack itself). The new power jack had all the connections to the jack just fine, so I plugged it in, connected it to mobo, put everything together and still no power.

Could it be that when the connections came loose originally the motherboard got damaged in the process? I felt almost sure it was the dc power jack as soon I saw those loose connections, but i guess not?

EDIT: To give you guys a better idea. I bought one of these: T61 DC Power Jack

I also tried plugging in the charger (which I've tested with a multimeter, and it is also a new chrarger) into the NEW port, then trying to get power from the contacts on the mobo connector (white piece in the picture). I tried pushing down with the negative connector to one of the black wire contacts, and pushing the positive tip to one of the red wire contacts and did not see any power there, so I'm wondering if I tested it wrong?

Hi, does anyone know what the problem is? I took out the screen of my old laptop, and put a replacement screen in. The screen its self (Samsung) is exactly the same model as the old one, except the inverter board looks a bit different. The laptop turns on fine with no screen plugged in, but when when I plug the new screen in, the only thing that turns on is the power supply light. I tried removing the new screen and it turned on fine. It's only when the screen is plugged in when it doesn't turn on. Is it because it's the wrong inverter board? I still have the old one. Should I just switch the boards? Thanks for all the help.

Gateway desktop GT4016, shuts off after awhile, now fan & light turn on for 2 seconds, shuts down.
Replaced: Power supply, motherboard, on/off switch, CPU, bypassed hard drive, optical drive, & memory sticks, still shuts down.
After replacing CPU, it came right on, ran for about 8 hours, shut itself down, played with on/off, eventually got it to power up & work for
another 6 hours, shut down again, now will not turn on.
Before this, substitued line cord, & different outlet.
History on this is I would have to unplug from behind a couple times, maybe more, to get the power to come on.
The data light would come on, but not the blue light to connect to the hard drive.
I transplanted the hard drive into a similar Gateway, but not compatible, got a blue screen trying to "learn files" but kept going round & round.

Anyone think of something I missed?

A:Hardcore Mystery, everything replaced on Gateway pc, still wont turn on

Typical cause is the power supply. Especially if disconnecting AC power solves the problem.

Are you sure the replacement power was good?

Also, OEM (ie: Dell, HP, etc.) Windows installs are keyed to the motherboard. Thus why moving the HDD to another PC doesn't work. Plus any differences in the hardware often cause Windows to crash or not boot as the needed drivers are not present.

Hi all,
I recently replaced spilled water all over my laptop. I make the mistake of not waiting for it to completely dry and attempted to turn it on.
So after, accessing the damages, I took my Lenovo Y50 to a certified technician who told me that the motherboard was damaged. I decided to replaced the motherboard by myself (purchased Lenovo refurbished from Ebay) and proceeded to install it.
When I turned it on, the LED lights up to signal that it is being turned on, however the fans do not start, my keyboard does not light up, my display does not turn on. (Basically, only the power button LED turns on for about 2-3 seconds, then shuts off)

1. I made sure the ram, harddrive, thermal paste, screws, cords etc was installed properly.
2. When I charge my laptop, the LED lights up to signal that it is charging.
3. I attempted to turn on my laptop without the battery, to this I received the same 2-3 second LED and nothing more.

Does anyone have any recommendations of what is wrong with my laptop?
Can we narrow it down to a specified region?
Thank you for your time guys, I really appreciate it.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

A:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I have a Toshiba Tecra M5 laptop without a functioning screen. The original screen died over the course of a couple of days. I believe it was the backlight. The screen would go very dark, but I could still see images on the screen very faintly. I would press the toggle switch that syncs with an external monitor a couple of times, and eventually the screen would come on again. This went on for a couple of days until finally I could see the screen trying to come on, partially lighting one corner, but unable to turn on.

I connected my laptop to an external monitor and was able to get by with that while I waited for my replacement to come. I ordered a "screen caddy" from eBay, the same model as my laptop sold as-is for parts. Among the working parts on it were the screen and the fingerpad mouse, which I also needed. The "screen caddy" is unable to boot, but it starts the process enough so that you can see the screen does work properly.

The trouble is that when I put the screen into my own computer, I don't get any image at all. The symptoms are different from my original problem. I'm not able to see images on the screen, even faintly. I can see that the backlight does come on. I've checked the connections and cannot find a problem.

I'm out of ideas for what to try. Any suggestions would be most appreciated.

Thank you.

Win 7 Pro system. Have 2 external USB drives, both networked.

Just replace an hdd that was still working fine with a larger drive. Upon turning it on, the driver installed successfully, and the drive shows up in Device Manager, but the drive doesn't show up as a Networked Drive in My Computer like the one it replaced. In my ignorance, I thought it would show up like always.

Attached is a screenshot of what I can see. Can anyone guide me as to what needs to be done here? Thanks.

Hello Forum,

Summary: Weird burning smell for 2 or 3 boots --> Doesn't turn on, no sounds or lights from comp --> replaced power supply --> worked for a few boots --> back to completely nonresponsive state 15 mins later (details follow....)

I do not know the system specs and I can't find them out without posting this issue at this time. It may not be that necessary to know the details but I can find out soon if necessary. Let's just say it is NOT a new computer - the motherboard is large - I could tell you the model in a later post - the processor is 1.x GHz, something like 512 MB RAM, I have 2 HDs. I am running Win XP.

Old Power supply: Was pretty old, up to 10 years old but maybe a few years younger (300 or 350 W). I haven't seen the computer much for 3 years since I started using and it was upgraded in the meantime.

One day I turned on my computer and shortly afterwards the room started smelling like burning metal/rubber or something acridly foul. Opened the case and nothing seemed to be boiling or noticeably hot, though I didn't really touch around. The only thing that was reasonably warm was the P/S. I thought I noticed the smell coming from it but it was only slightly smellier in that area, at most. Didn't add anything special or change anything in comp recently beforehand. Played loud music on in the night before but the speakers have their own power supply.

So I decided to replace the P/S - I purchased an hec HP485D 485W ... Read more

It's extremely likey that when your PSU blew it damaged your mobo as well. If you have removed and replaced everything else and nothing works then it's either your mobo or cpu. In this case it's likely your mobo.

Hello TSG,

My girlfriend is having a few difficulties with her 500GB Buffalo External Hard Drive. As of this morning, her Laptop hasn't been able to turn on if the HDD is plugged in, and if she plugs the HDD in while turned on the Laptop doesn't recognise it and Blue Screens after a few minutes.

She hasn't had the Hard Drive long (coming up to a year now) and her Laptop is a Fujitsu Siemens with Windows 7 OS.

She says she doesn't want to reformat (though it sounds more of a power issue to me) if possible, as she has a lot of photographs and work on there she doesn't wish to loose.

If anyone has any idea what's wrong, please let us know!

Thanks a lot!

I just advised her to try plugging the EXT HDD into another plug socket, and low and behold it works again. She said however that when she plugged it in, blue sparks flickered at the socket for a few seconds, which really doesn't sound good...

Any idea if it's the HDD's plug itself going... or is it the sockets in her room? <_> Cheers.
