PC powered off and wont power on?

Q: PC powered off and wont power on?

Was browsing a website when my pc just powered off,tried to turn it on but the blue light flicks for a sec and it wont turn on,i have a usb ext hdd plugged in and the light on it is green,so think this rules the motherboard out,also take 1 stick of ram at a time out and tried to power up,still no power,took sound card out,still no power,im thinking psu,but why would the usb lightup the ext hdd,anybody any ideas before i take it too the pc shop in the morning,they fitted a motherboard for me 3 months ago,so if its the motherboard it should still be under warranty~?

Many Thanks

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.)

A: PC powered off and wont power on?

Try disconnecting everything non essential 1 at a time. If you disconnect 1 thing and the computer comes on, you'll know what is caysing problems. Just because a light lights up or a fan spins only means the PSU is putting out some power. It does not mean that it is putting out enough power to run a computer. If you have access to another known good power supply, try connecting that and see if it comes on. If needed, see if you have afriend that will loan you one to test with. The PSU you have is one of the better PSU's you can buy. They rarely give you problems. Try those things and let us know the outcome.

Hi, I have a ASUS Crosshair motherboard. I upgraded from my old power supply that was 500w to a Antec TP-750 that is 750w . My MB worked for a couple of minutes and then shuts off instantly. I powered it on again and it shuts off instantly about 10 seconds after the boot screen. The MB don't want to stay on at all. Can anybody tell me what is going on with the motherboard?
 

A:My motherboard wont stay powered on

You can try using you old power supply again ( if it isn't defective ) and see if you MB works again. If so, there could be a problem with your new Power Supply

Hiya Guys.

Something strange has been happening to the USB section of my computer and I wondered if anyone could shed some light on it for me.

I bought a USB powered 1TB external hard drive (ie: the one USB lead gives it power and data transfer). I connected it directly to a computer (XP Pro - SP3) and it found it, installed it and I was up and running but when I connected it to a 1 metre USB extension lead in the same port on the computer, it failed to install and the drive started clicking which we all know is a bad sign.

After re-connecting it directly without the extension lead, it went straight into it and worked like a dream until out of interest, I connected it via the extension lead and again, it failed. I don`t think the drive is at fault as it works every time when it`s a direct connection and fails every time it`s through the extension.

In case you`re wondering, all ports are USB 2.0 rather than 1.1 and as I have access to a few other machines, I`ve tried the `test` on those with various leads and directly, ending up with the same results.

My question is ... Can a USB extension lead take just enough power that it tips the balance and not give the drive enough to initialize itself?

Regards Jenny

Ok, I just built a new computer that I ran for about 2 hours give or take then it powered down completely during my OS installation. Now it won't even power up at all, I switch on the power supply and the green led on the motherboard lights up, pressing the power button however does nothing.
My worst fear at the moment is that I have fried the CPU by applying too much thermal conducting past between it and the heat sink. (I didn't apply the thermal conduct myself, I had my room mate helping me, I wasn't aware of how much was supposed to be applied.)
Now the question I have is, would that be the reason why nothing happens when I hit the power button even if the green light is on?
Another thing to note is that the cpu heatsink fan I bought already had a small amount of Thermal paste on it which we failed to notice right off.

Dynapower is not a brand that I recognize, if it is a low quality PSU then that is probably the issue.

Thanks for the happy birthday i wouldn,t have found u otherwise. I downloaded "Demo Version" Jv16 Power tools 2005 from a link to find duplicate files and clean my registry, I thought that programs I had uninstalled and reinstalled for varius reasons were all duplicated with missing files. The download didn't have the handbook which i found out later i needed so now after running dup. file finder, reg cleaner. I have a very unstable system nothing stays stable and there is a mass of backups I don,t know where to start. The forum there won,t help. supposedly I got a old Beta version. My backups don,t look anything like there's. I would like to go back to before i installed with system restore point but i dont know if it can retrieve files from Jv16 backup or what. logitech, hp, msn, registry changes, no cd drive, I have never deleted any backups from spybot or AVG free if they would help. I am a novice at forums and i'd like to show you what I did but you would have to tell what to link or paste. it sure looks bad. Even if I minimize this window and look for something I lose you.

This is my second powered USB hub and they both will not allow my PC to boot while the hub power is connected. When I press the power button on my PC it reacts just like the button don't work but as soon as I unplug the hub power it starts to boot OK. At the moment I only have a Razer mouse plugged into the hub. I tried different USB ports on the back of the PC for the hub and same thing. It appears to be a power conflict with the hub and the motherboard? Any ideas?

I have a Dell 1525 Inspiron laptop..i believe is about 3 years old. I got it as a hand-me-down from my BF's mother, who took excellent care of it. Ive only had it since February, but it has always run fine, until this past month. 3 times now it has done this to me. The first time, it was just after I unplugged it to take it to a friends house..then tried to power it up about 1/2 hour later and nothing...let it sit for 2 days or so, and then it was ok..now it has happened 2 more times..but these times, it froze up and wouldnt unfreeze..then when I got it powered down and tried to get it back up..nothing...the second time it again took a few days then it was ok..this last time it has been a week and nothing yet. This time, the only thing that is different is that the 3 lights to the left of the power button are blinking, the caps lock, numbers lock and scroll lock icons.. It powers up, then shuts down within 5 seconds or so...but the power light and the one fan keeps running...Ive been told multiple things so far..from a bad battery to bad power cord to bad connection in the lappy where the power cord connects.. I just dont understand why it powered up those 1st 2 times and it wont this time..unless it was just a fluke those times. I dont have alot of money to fix it, or replace things unless i know for sure what im buying is going to work. I dont want to lose whats on it either!! help!

Hey, I'm using a Lenovo T430s (Windows 10) . Recently, my DVD RW Drive showed it's powered off, and it wouldn't turn on saying that a specified module of Power Manager wasn't found (see the pic 1).

Hello,

System Specs:

Motherboard - P5N-D
CPU - E6700
Memory - 2x2GB Corsair XMS2
Video Card - Radeon HD 5870
PSU - Thermaltake 750W

Problem:

Computer powered off while in the middle of me using it. Tried to power back on, but nothing happens when the power button is pressed. Tried unplugging the power supply and back in, still would not power on.

Troubleshooting:

Hooked up my PSU to a PSU tester I have = Good

Replaced Motherboard = no change (indicator light is on, on the motherboard)

Checked power switch = Good

I also tried taking out my video card, left one stick of ram in, and still nothing.


----------

The only thing i haven't checked is my CPU, I have just ordered the E8400 in hopes this will fix my problem, but I was hoping to get a little feed back on my situation as I have come up empty when searching online for a simlar problem.

I appreciate any feedback I can get!

Thank you!

Hello Community I've got a brand new P52 with a Thunderbolt 3 workstation dock. Unfortunately the system is not getting enough power to keep it running. If I attach the power to the system the battery is getting charged, but as soon as I boot the system up, it reports that it is not getting enough power to run the system. It doesn't matter if I attach the system to the workstation dock or to any of the power supplies directly (170W or 230W). As soon as the system is booted, not enough power is being supplied and the system runs on battery. I've already installed the latest drivers to both the system and the workstation dock. Any idea how to fix that? I've tried to open a ticket at this brilliant eService Ticketing, but this won't let me create one.

Now heres the issue im having thus far. All components are are set. Pc is ready to be powered. Unfortunately this case has no pc speaker, so i cant listen to the beeps upon powering on. Hardware not functioning properly: dvd drives have power, but tray doesnt eject.

The system will power on when i flip the power switch on on the back of the psu. power and reset on front is non operational, yes theyre wired properly. pc can only be powered off by turning off power on back of psu. onboard reset and memok! are working properly. pc wont boot to bios stays at black screen and monitor goes into powersave. All usb ports are working, yet my keyboard doesnt seem to be operational. guess that can be expected if pc isnt going into autoboot like it should upon being powered on for the first time.

Water cooling is fully functional as are all fans and leds.

Video card appears to be fine as far as the eye can see.

Does such a thing exist?

I sometimes find I need my external drive for like 5 minutes on the road without a socket in sight so it'd be great if I could just have it suck power from my computers USB port.

Or even solar power.

Obviously I wouldn't power something for a long time with it.

Or it'd be great if only one plug is available like at a coffee shop

Anything like this on deal extreme?

A:USB to electrical power plug? / or solar/AA powered

I think the best solution for you would be a portable hard disk that don't need external power supply. I've been extremely happy with Western Digital products, using this 640 GB as my "on the road" drive. It fits to my jacket pocket.

I am using the usb hub to switch a USB relay board to which using a volt free switch to send a signal and power a LED traffic light in a sequence.

I have external power supplies powering the LED lights.

It started intermittantly and I need to restart the computer to allow it to work again or turn off the d-link hub and unplug the usb.

I can get it to error sometimes with just plugging the usb powered hub into the computer with nothing else connected to the hub other than its own power supply.

Hi all!
I've got a strange problem that I've never encountered before. I had a power supply go bad and I replaced it with one I know to be good from another pc. In fact, I bought a new one also.
This happens with both power supplys.
The pc is a Emachine T2882 w/Celeron 2.8G running XP Home.
Anyhow, when I power the pc down I noticed that the heat sink on the processor was really hot and I also notice that the little light in the front that tells you the HD is working was on AND I noticed that the fan in the power supply was running. All this when I powered the pc down via the START>Turn off computer>Turn off
This could be what burned out the power supply in the first place.
Has anyone ever heard of this? Can someone help me out with this strange scenario?
Thanks so much and may God bless,
Peter

Hi, the old girl is generally still going. My issue is now that when the x1 is powered up and plugged in it does not permanently recognize that the power cord is plugged in and alternates every second between battery power and cord power. As a result it does not charge sufficiently and runs out of battery at some point. When powered down and plugged in the battery charges over several hours and the laptop can be put back in use. The cord seems fine and the green light on the side of the computer when plugged in does not flicker.. Thanks for your ideas.

I've recently built a machine and whenever I boot up, a message is displayed saying: "The Nvidia system sentinel is reporting that Nvidia-powered graphics card is not receiving sufficient power.

To protect hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations."

I am not sure as to why this is happening. My PSU is 420 watts, which should be more adaquate for my Athlon 5X-53 and my AGP GeForce FX 5200. I have the molex attached to the video card and the video card is seated properly in my mobo. Any ideas on what the problem is? Are we looking at replacing the PSU, motherboard, or video card?

Hi there

Intuitively one might think using Powered (from the mains) external USB HDD's would require more power from the computer as well compared with those small self powered units.

I've no way to measure this but I'm sure the small units might consume MORE power as the computer has to supply all the power for Disk rotation and the USB I/O controller.

I only ask this because I need to put two large powered USB units (both with 2 X 3 TB Raid 0 HDD's in each unit) on to a USB 3 Hub.
The two HDD units seem to perform perfectly well whether connected to the chargeable port on an HP laptop or the "non chargeable" ones.

The RAID 0 is powered by the HDD itself (internal Hardware RAID) --used RAID 0 for speed -- don't need to mirror etc - I've enough backup if the whole thing goes bonkers. !!

The files on these HDD's are serving music and video so not intensive used -- don't seem to have any problem streaming media from the laptop.

Any engineers out there - curious over what is the actual load (power wise) on the computer if a POWERED USB HDD is used compared to a Self powered one. Note the Hub I'm using is not also powered.

I have a WLI- CB HP 54 Buffalo wireless network card and it is supposed to reach further than regular wireless G cards, but my internal wirelesss on my laptop spans MUCH further.

I am using Windows XP SP2 and installed the driver and software about 3 times. I have found that windows configures it better than the software that came.

My question are a couple.. First. when i go and set up wireless zero configuration service to automatic, it keeps going off the next time i restart and when i search for networks it says "make sure your switch is turned on " .......

I called Buffalo and they said that it was my internal PCI adapter interferring with it. It is an A/B internal card. Within close range, the wireless card works fine.
I also wanted to know if there are dangers of having my internal A/B card and a wireless G card running at the same time.

Also the Buffalo says it is B/G, but doesn't pick up B networks well.

Thank you for your help.
 

A:Buffalo High Power Card Not high powered

Is your router A, B, or G? Also, I can't think of any danger, per se, of running both cards. This is a process called Multi-homing. If you plug in a LAN cable, you'll actually have 3 network connections, 3 IP Addresses, etc. Some apps may get confused & blow up, otherwise you're just using some resources unnecessarily. If it was me, I'd turn off the internal card if I had a G card I'd rather use...

Ever since i got this new motherboard and CPU ive been having a bit of a nightmare with it.

AMD Phenom Black Edition 9850,
4 gigs PC 6400 ram (Corsair XMS2 CM2X1024-6400

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)


It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

Hello, I have a one-two year old Compaq Presario and it has stopped receiving power a couple of months ago. The battery currently doesn't work.

Last night my computer blue screened about 3 times then it just stopped turning on altogether. Wheni plug the power supply into the motherboard the neon fan turns on for a milisecond but that seems to be the only way that i can tell that there's power going to the motherboard.

I've tried 4 different power supplies, different processor, different BIOS batteries, different RAM, etc, but no matter how many times i try to turn it on it just wont turn on.

I do recall doing something innthe BIOS last night which seemed to start this dilemer. I went into power management and did something to the power switch option, then set everything back to default settings.

This is when things started to happen then my pc just wouldn't turn on at all.

It's a socket939 MSI CoreCell.

Could something i did in the BIOS really be causing this problem and is there a way to fix it?

Like i said there does seem to be power going to the motherboard but it simply wont turn on (i even tried different power switches just in [email protected]

Any help would be greatly appreciated. I just don't want to buy another 939 motherboard as most shops don't cell them any more and it means i'd have to buy a new processor too.
 

A:Computer wont turn on with power switch but there is power going through it?

If it is a BIOS setting, removing the CMOS battery for a few minutes should clear it. Since you've already changed the battery more than once, it would seem that is not the problem. Considering what you already tried, it might be the motherboard itself or possibly the graphics card but my money is on the motherboard. Just to be sure do you have another graphics card to test with?

I was running Ubuntu Linux then decided to change back to Windows XP. I was happily running the Windows set-up disc to reformat the entire hard drive. After this was done, the set-up disc went on to copy over a load of files and then went into a reboot, the screen went black (OK) but then everything just hung . In the end I went to power off intending to start again. The computer would not power off except by my pulling out the battery and supply cable. If I reconnect the cable, I can power on with the power button after which I hear the fan and the optical drive being read but then it just stalls - nothing on the screen, cannot get in bios and still refuses to power off. It"s either a big coincidence or the three symptoms ( no screen: no bios: no power-off ) are all a result of the failure to self-reboot during the windows set-up? I have removed the CMOS battery and left it out overnight but to no avail Can anyone help? My laptop is a HP Compaq NX6325. Thanks.

A:Laptop wont boot and wont power off

The first question is hardware or software? That this happened in the middle of a Ubuntu to XP conversion is interesting, but may be purely coincidental. It could be a straight-up hardware problem that just happened to occur at this time.

So, the way to determine this is to try to boot using some kind of media. XP disk, Ubuntu Live, Hiren's, whatever. It if boots, hardware is possibly good. If not, hardware is bad.

If hardware is bad, you WANT the hard drive to be bad. Everything else costs more money than the computer may be worth.

My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.

Question 1-I any ideas what causes the computer not to power on when it has sudden power loss?
Question 2-What can I do so that the next time I have a sudden power loss I don't have to take it apart to get it working again?

I like learning computer/electronics repair so be as detailed or technical as you can be to help me learn more about electronics.

Thanks

A:Computer wont power on after power loss

The power switches do go bad and can result in all kinds of strange behavior. You might try replacing the switch.

But before you do try removing the switch and starting/stopping the computer using just the wires to see if it is indeed the switch.

Hi !! All,

Happy New Year to all members and technical assistants.

I have a little issue in which I require some help and guidance.
I have a PIII 900MHZ 256 MB memory with a ASUS MB-

Recently it died on me and assumed that the reason I could not get to power
it up is due to my power supply. I went out and spent the money and bought a brand new power supply from a computer retailor. I saw him remove it from a brand new case.
I installed the power supply , trying to power it up, I can see the fan rotate a little bit but not enough to power on. Changed socket and it power on.
It booted up but after 30 sec, it shut itself off and now I cannot power it back on until 15 min. later when I went and change power socket once more.
This time, the power did not stay up very long. As soon it powered up, no more than 1 min later while it was loading windows Xp, it shut itself off nad now again can't power it back on. I have a power extention and power bar in which I used and both shuts the computer off. Anything else plugged to it doesn't seem to do any affect. This is the second new power supply I'm trying.
What else can it be ? I have not tried to place the computer in a different room on a different plug yet. I will try that tonight but in the meantime, what else can I try ?

Thanks for your help and listening.

Cheers !!

I had a similar problem once and someone told me its a virus attack.... Its probably the same for you too. I had to format the C: drive and re-install the OS then. You may try that too...

Last night when shutting down the virtual machine within Win7, the virtual machine hanged. Win7 gave me the option of doing a forced shutdown, which I accepted. But now this morning when I try to re-open the virtual machine (which is powered down) I keep
getting the error message "The virtual machine could not be started. An unknown error occurred."  PLEASE HELP: I have months of research stored in the virtual machine which I need to retrieve. Any suggestions gratefully received.

So I turn my computer off one day only to find it wont start the next day. I open the case up and see the led is on. I flip the switch on the power supply off then on and quickly press the power button. My computer starts but the following time I shut down the computer it again wont start and now the led is blinking. I've never had any issues like this before, any help would be appreciated.

I don't routinely use many usb devices, only my mouse and keyboard and every now and then my ipod. I figure the issue is likely either the power supply or the motherboard. The ps is almost two years old while the motherboard is only about three months old.
 

A:Computer wont start, power supply wont start, blinking led

It sounds to me like your PSU is the problem, get a hold of another and plug it to your computer and see if that will make it start, if it doesn't it might be BOTH your motherboard and PSU. A bad PSU will burn a motherboard.

I bought the laptop used. it appeared the battery wsdead. I bought a new battery. The battery would stay at 53 percent and when i would unplug the charger it would immediatly shut off. i troubleshooted in the device manager and reset the laptop. Nothing happened. I reset a second time and the battery was charging and the laptop would run off battery power. this soon stopped working. I continued to troubleshoot. i got it to charge again and run off battery power but now it will again not run off battery power. the battery is now at 74 percent so i know at some piont charging was happening. this is very frustrating. Iv built a gaming pc jst recently and i feel like i should be able to figure this out. Any help would be much appreciated.

I shut down my rig a couple weeks ago and went to bed, the next day when I attempted to power it up it wouldnt turn on. All it would do is flash the led's on my case fans right quick and that was it. Immediately I thought it was my power supply but I wasnt sure how to confirm that so Ive let it sit. Last night I decided to open up the case and do a visual inspection, make sure everything is connected, look for obvious stuff, before I opened it up I figured Id try to power it up again....What it does now is as soon as I turn on the power supply, all of my case fans light up and spin at a low speed, the cpu cooler fan lights up and spins slowly too, the psu fan lights up but doesnt turn on, even the gpu fan spins, all at approx the same slow speed. I can even hear the hd spinning slowly too. Pressing the power button on the case does nothing at all. When I turn the psu off, the case fans flicker and then shut off. When the fans are lit up, its not at full tilt, its maybe 50-75% as bright as they normally are.

Does this sound like a psu problem or something else? My rig is approx 5-6yrs old and I do plan on building a new one regardless if I get this one up and running again bit Id like to get this one going again if possible so I can start prepping for the new rig......plus its killing me not to be able to update my music on my ipod. Any way I can test the psu to see if its the cause, short of buying a new one?

This just happened one day, but might PC will now not boot up with the graphics card in. It's an older PC (hp p6130f with a 450w PSU). I put in the EVGA GeForce 9600GSO a few years back, and everything worked fine. Now for some reason it won't boot up with the card installed. Any ideas as to why this might be? The card does not have an external power source by the way, and only requires 350w.


Any ideas would be greatly appreciated.

I've unplugged and replugged in everything, reseated the card and reset the CMOS.

A:Wont power up, cant keep gpu in.

Could just be that the card is knackered or the slot has gone bad on the mobo, hard to prove either way unless you have a different slot the card will fit in, another pc to try it out in or a different gfx card to test in that slot

I'm fairly adept at building and upgrading computers but don't know much about diagnostics. My situation:

I'm upgrading my computer and at the same time moving my old board (mb, cpu, ps, and video card) to my wife's (even older) computer. My problem occurred while putting my old board into my wife's computer. I've done this probably a dozen times plus I built both computers. This time after the install I powered up just to see the cpu and video card fans spin for a couple of seconds and then quit. It would not react to a second push of the "ON" button unless I first removed and reapplied power to the unit and then it just repeats the momentary on scenario.

Abit AX78
Diamond HD3870 DDR4
AMD 64 X2 5200
G.Skill 2 x 1GB DDR2
Thermaltake TR2-430W

The legacy components include:
WD 1600
2 DVD RW drives of unk mfgr
1 floppy drive

The motherboard and all its components and ps were working fine when I pulled them from my computer. Any help would certainly be appreciated.

A:wont power up

I know it's basic...but check all connections before moving on .

I would also try her original PSU with the new board.

Hi All

My husband's PC died.
It wont power up, its starts to, but then it dies right down before it gets to loading the operating system.

A few months before it died, it started having issues with - he would turn it on and it would give a black screen with just a blinking cursor in the top corner. He would shut it down, wait a few minutes and restart it and then it would start ok.

Where should I begin to troubleshoot whats wrong with it?
 

A:PC wont power up

Check the motherboard for swollen or leaking capacitors, they look something like this: http://www.macmedics.com/images/imac-logicaboard-with-leaking-capacitors.jpg

If this has happened, you will probably need a new motherboard. It is repairable, but it's a difficult soldering job.

HI,

I'm not sure if this is the right forum, so apologies if I'm not in the right place.. but wanted to ask if anyone has any ideas what I can do. I recently took my Mum's PC as we were clearing her house. The PC was working fine.

I set it up at my house, and when I turn it on the light comes on for about 2 seconds, the fan comes on and then the light and fan goes off for ten seconds or so, before trying again.

It is almost like there isnt enough power to get it going, but have tried it in different plugs around the house, and get the same thing?

Any ideas would be very much appreciated.

Thanks

i have a dell dimension 3000 running windows xp. my problem is it wont fire up. i only get a flashing amber light. no fans but a little green light is on on the mother board so im assuming its getting power. also the cd burner goes on but the computer will not, any suggestions? also i am an idiot when it comes to computers so any responses should be simple
 

A:wont power up

Does your Dimension have 4 round LED lights on the back numbered 1-4? If so, if any of them are amber in color, the pattern will indicate what is wrong. For example, if they are green, green, amber, green. That means something different, than amber, amber, green, amber. The codes for this can be found here: http://support.dell.com/support/edocs/systems/opgx620/en/ug/tools00.htm

Good luck.

Well i wake up this morning and my pc was off. I just happen to leave my pc on last night. I go to turn it on wont turn on. No fans are coming on. Nothing. i make sure outlet is working. It is. Could it be that the PSU went up?

Hi untitled23

Yea sounds like your PSU has quit. Try plugging the computer into another wall socket and see if it comes on. Did you ever get a burning type of smell from the back of the tower? Also, if you have one, try another power cable - this could also be the problem. PSUs have a tendency to fail often unfortunately.

Hi, my pc case is far past it's time and the front panel has been falling off for some time. I knocked it with my char and now it won't turn on. I think it might have pulled on the wire that connects the on/off switch to the mobo and broken it. I'm not sire what to do to fix it. Is there anything I can do to diagnose if that is what's broken or if it's something else? Also if that is the problem I'm not sure what to do to fix it. All help is appreciated.
