Power Supply Died, Replaced With Old One

Q: Power Supply Died, Replaced With Old One

I built this new computer about a month ago.
core i5 2500k
GTX 570
8gb of ram
Windows 7
Old Power Supply: http://www.newegg.com/Product/Produ...ords&cm_mmc=KNC-GoogleAdwords-_-pla-_-NA-_-NA

It's a pretty by the book build. Last night though, I walked into my room and noticed the power off, and it wouldn't turn on. I opened it up, checked all the connectors, gave it another shot, and nothing.

My old computer had a 750 watt Cooler Master (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171024) in it, so i took that out and tossed it into the new system while I wait for OCZ To send me a new PSU. Everything seemed great, I did my normal tasks for the rest of the night. When I launched Battlefield 3 though, the PSU actually makes a very odd buzzing noise. I don't remember this at all from my old computer. The red warning light doesn't go on or anything, it just buzzes. It also happens in Dungeon Defenders. The second I turn either game off, it stops.

Right now I'm back to basic tasks, but is this just due to the extra load from the new system? My old computer probably could have run fine off something much weaker than 750w (it had 8800 gt / Q6600), so I'm wondering if this it's just finally getting a workout or something. It has always run fine, I'm not sure why it would act up in the new comp. I'm sort of stuck until OCZ Gives me a replacement. Is it safe to run this thing?

Preferred Solution: Power Supply Died, Replaced With Old One

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.)

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

Hi, this is my first post, so I hope I can explain what happened to my pc clearly. I have an older gateway 450mhz and recently I tried to power it up and nothing happened, like it didn't have power. So I reset my power strip thinking it just tripped the breaker, and it started to come on, I could hear it power up and then it just shut off again, no power, lights or any thing. so I plugged it directly into the wall. and the same thing happened, started to power up, and it was like it would reach a certain power level and trip some kind of internal breaker or something.
Hopefully there's someone out there that knows whats wrong and if its worth fixing..... Thanks alot for any replys

A:I think my power supply died !

Hi all,

my power supply died two days ago. By chance, everything else seems in
order, except for the USB ports which act strangely.

I bought a new power supply and installed it. The computer boots normally
and the OS starts without a problem when there is no USB devices plugged to
the motherboard.

If I try to plug something to the USB ports while the computer is on, there
is no problem and all my USB devices work fine.

But if I boot with the USB devices plugged to the motherboard, the computer
doesn't even try to boot (nothing happens when I press the power button).

Someone have a hint?

If the USB ports are not working properly, should I change the motherboard (in case it blows up something else with time) or just disable USB ports and buy a PCI USB card?

Presently have this power supply:

Antec BP500U ATX 12V 500W Power Supply


Computer overheats and shuts down. On checking, the fan in the power supply stopped working. Looking to replace the power supply with a different brand. The fan in this one was LOUD.

I'm running an Intel Core i7.

Does it matter what brand/type I replace the power supply with? (I see 550w, 600w, dual power. Should I consider any of these?)

Are there any recommended brands/models that keep it very cool and very quiet?

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 !!


A:Pc wont power on after power supply replaced

I recently had my power supply die on my and got it replaced.

Since then I have not been able to print to my hp laserjet, or use my logitech Wingman controller which are usb devices.

I have an intel pentium 1.7 GHz with 512 M ram running Windows XP.

The laserjet appears to be recognized. When I unplugged it and plugged it back XP told me it had found a new device and set it up, but it always sets it up to work off-line. When I put it on-line I get an error message when printing about the printer not being connected properly.

When I tried to manually add the Wingman it just said device not connected and I couldn't do anything else.

I went through the trouble-shooting guide, including deleting all the usb connections and rebooting. Everything got added back but I still had the same problems.

Any advice would be welcome.


A:usb problem after power supply replaced

A dead power supply is not a good thing. Did it go out with a bang or popping noise? There is a 50/50 chance it may or may not do damage to the components inside the pc.

I recently had to rebuild a pc for my wifes father. When the psu blew it killed the motherboard, cpu, memory and hard drive when it went.

Im wondering if when the psu failed it caused a surge in your system and could have damaged components on the motherboard. I would definately take a look at the motherboard up close. Look at the capacitiors. Check to make sure their not expanded, leaking, or blown.

As for your usb and printer problems they could be related to the motherboard being flaky due to the power supply failing.

This of course is only guessing at this point, but i wanted you to be aware of what can happen when a psu goes out.

More info on your system would be greatly helpful......

Several weeks after I bought this computer it started randomly shutting down on me I called tech support @ ComputerLX.com where I purchased the computer and he gave me the run down on getting an a new power supply covered under warranty. I did this sent in my old one and installed the new one and it worked fine for a couple of months and started shutting down on me again. I dealt with the nuisance and turned it back on whenever I could and limited my use, sent in the power supply and got a new one again, same scenerio 2 more times finally I decided to quit using the **** power supplies this guy was sending me and went to my local TCComputers and bought a 730w Kingwin Max Power PS. I know this isn't a top of the line PSU but its 200w higher than the others I've had in the past and much better quality. Well, I bought it on 6/10/10 4 months ago, and for the last 2 months I have been having the SAME shutdown issues.

If anyone could PLEASE PLEASE help me shed some light on this situation I would appreciate it sooooo much.

Thank you in advance for taking the time to read my post.

Put in a new 430W PSU (Thermaltake) replacing the 300 watt Power Man which was about 6 years old. With better specs obviously.

Now I see that the apps open and run quicker.

Is this my imagination? Could the power from the older supply have been strained, with what amounted to slower delivery - or maybe the vid card drawing too much % from PSU?

Should food also taste better? Colors around me, pulse more vibrant?

I have a 6.5 yr old e9180t which the power supply died on me this weekend. The unit has an interesting history. The mother board was defective when I bought it and they had to finally replace it along with thousands of others. This unit coined the term inherently defective with google at the time. They rolled it our before really vetting it properly. When I looked inside the box when I first got it I noticed how crammed the interior was compared to my previous unit.  This unit has always run HOT. After years of the heat build up I eventually just removed the side panel due to the heat. So when the power supply died this weekend I discovered another big design problem with this unit. For the first time I removed the top plastic panel . . .  this panel completely hid and covered a vent for the power supply the whole time! The vent was completely covered with thick dust. I literally had to peel the dust off this area. I always used air to blow the dust way inside but since there was no vent visible I had no idea about this issue and never saw the need to remove the top plastic cover.  So I plan to replace the power supply and have two questions. 1. First what is a good replacement? I see that EVGA makes these power supplys where both ends of the wires are plug in which seems like a perfect DIY approach. The current dead power supply was a Samsung 460watt HD642jj. I use two 27" hp monitors with this unit and work on graphics mostly during the da... Read more

After posting this I thought about the issue with the power supply and HP must have installed the power supply upside down and that is why this power supplied died and why this unit was always super hot. I just looked at the power supply and yep I think it was upside down. For years I have been plugging this in on the upper right hand side not the left hand side. The only person who has worked on this computer was the guy who was hired by HP to replace the motherboard after two months since the board was defective from the get go. I wonder if he had taken it out and put it back in wrong? I don't know since I thought HP and the guy knew what they were doing and I had no idea to keep a close eye on how the power supply should be. Unbelievable!

Bit of a long story for this but bear with me.

I was playing a game this past sunday when my main pc lost it's power, after it died I heard what sounded like metal hitting metal within my case, I took my power supply out and took it apart to find what looked like a coil wrapped around a plastic tube, half burned, so I guess it melted itself off. It was my fault as the inside had tons of dust clogging the fans and vents. Luckily I had a backup for just such a problem, I borrowed the power supply within this secondary pc, it has a 1000watt psu(sli ready) whereas my old had a 600w(also sli ready), I figured it would be a more than suitable temporary psu until the replacement I ordered arrived.

However for whatever reason it won't work in my main pc, whenever I boot it up, everything seems fine but after so much time of being in use the pc just loses power. If I do nothing it will stay on, if I do anything other than idling it loses power. If I scan using MSE it always crashes around 7 minutes or so of scanning but spybot can scan completely, if I browse it tends to take a bit longer to crash (around 30 minutes more or less). I have ran a temperature detector in the background as I scanned and did other things and nothing ever went above 50C so I'm fairly certain that it isn't a heat problem.

To be honest I've been pretty lucky with most of my past pc's, I've had this one for about 8 1/2 months and other than a few random crashes this has ... Read more

Hi. This is the story. In the middle of my son using the computer, it just shut down. I came down to the room where it was a minute later, tried flipping the master switch on the surge protector off and on, then pressed to power button on the case. It started up. A few minutes later my son called me again because it had shut down again. The former trick didn't work. Here's what I've tried:

Flipping the I/O switch on the power supply both ways and trying to power up.
Unplugging the power supply from the surge protector and plugging it with another cord directly into the wall outlet. Then flipping that I/O switch again.

Nothing happened. Does this sound like it's the power supply?

A:Computer died!! Is this a power supply problem?

First time poster here, hope you all can help me with this.

Yesterday the power supply burnt out in my Dell Dimension 9150. It had a 375W power supply and I upgraded to a Corsair CX750M (750W) because over the years I have added and added to the motherboard and maxed it out! I believe maxing out the motherboard is why the power supply burnt up. That or the age of the old power supply.

Anyways, after installing the new power supply, I was able to turn on the computer without any issue. However, as the Windows 7 logo was booting up for the first time, the Windows logo froze and then the screen flashed a quick blue and rebooted. After multiple times of running the repair option from the system files and then also trying to repair from the Windows disc, Windows 7 still will not boot. I even went into the repair mood and tried rolling back the Windows settings to the earliest save point and Windows still will not boot up.

I have seen a message that says it's a hardware issue and that if I have installed any new hardware recently, I should remove it. But the power supply is the only new hardware. Did I miss something, am I supposed to change a setting in the BIOS?

I did also change out the motherboard battery when I had the case open, but the BIOS seams to have saved all the settings. Any ideas guys? I would hate to have to reinstall Windows 7.

We had to replace the power supply in our desktop running Win XP, and since then, we have been having trouble with our browsers. What happens is that when multiple sessions are running (most usage is to view Youtube videos), after a while, the browser will hang for a long time and then come back with a "page not found" message. Closing the browser and opening a new browser session does not resolve the problem, and this appears to happen in both Firefox and IE. Rebooting the computer resolves the problem, but after a while it happens again.
In all other ways, the computer is acting normally.
I have tried uninstalling and reinstalling Firefox and all add-ons.

Any advice or ideas would be appreciated.

The power supply on my 4-yr old custom build recently gave out. I replaced the PS, and the machine is running normally again, except I can not get sound out of the speakers.

Here are what I believe to be the pertinent facts...
Sound worked completely fine prior to PS replacement
There are no errors being thrown that I can see
Volume is turned up and speakers show that they are un-muted.
When sound file is playing, the level indicators are registering positively.
Gigabyte motherboard has Realtek HD audio
The Realtek audio manager indicates that the speakers are the default output
Headphone output via the front-panel jack is working OK
Line-in via the rear jack is working OK
I have tried both options for headphones mute speakers and headphones and speakers are separate output. Still nothing from speakers.
The machine is dual-boot Win7/Linux. Sound from speakers works correctly when booted in Linux.
Tried unplugging the front panel header, no difference.
It acts like the speakers are simply muted, but there is no indication of that anywhere. I've messed with it for 2+ hours and have gotten nowhere.



A:Replaced power supply, now no sound from speakers

Try uninstall/reinstall the RealTek. Go to the Device Manager, RIGHT click on the RealTek entry in the Sound section. Then LEFT click "Uninstall". DO NOT uninstall the drivers. Restart the PC and when Windows starts it will detect and reinstall the sound. This corrects any Windows sound corruptions and may fix your problem.

Greetings all!
This is my first post and I'm hoping to be able to reciprocate with answers from my own knowledge and experiences, though limited. Thank you in advance for your kindness and patience.
I have an older PC (six years) running Windows XP (fully updated) with an Athlon 64 CPU, 2G ddr, 250 GB Hdd, onboard Nvidia graphics chip set on an Asus motherboard. For years the system has been stable & reliable but last night I found it dead. After troubleshooting the basics (power strip, power outlet, power cord, on/off switch etc.), I figured a new power supply was in order since everything worked fine the day before and then nothing. So... while putting in a new TEC 385 W PSU I noticed the 20 +4 connector was different from the old 24 plug. Stupidly, (looking back) I left the 4 plug off. Also I noticed a six plug connector for the PCI express but no receptor on the motherboard for it. I figured since I had nothing in the PCI slots or the PCI express slot,; no big deal, just leave it unconnected. Power on and I see a small amount of SMOKE coming out of the carriage near the front panel USB/1394 connectors and the Hard drive! Quickly unplugged & rechecked all the connections. Didn't find a problem there. Plugged the 4 pin connector next to the 20 pin on the power connector (finally) and tried again. This time no beep, CPU fan spins up, Chassis fan spins up, hard drive does not spin up and the HDD light on the front panel stays lit. Nothing (not ... Read more

A:Replaced power supply and now no video or HDD spin up!

Also I noticed a six plug connector for the PCI express but no receptor on the motherboard for it.Click to expand...

this is rather confusing, first of all the six pin PCIE connector plugs into a PCIE Graphics card that requires a a 6 pin connector, not the motherboard, secondly, did you plug in the 4/8 pin CPU power connector (i'm assuming its a 4 pin on a machine that old.)
Thirdly, and I don't know if its possible to force it in or not...but was the 4 pin you eventually plugged into the 20+4 the CPU power plug? was there a bit of force involved?

Long story short. My power supply shorted mid week while my computer was booting up. Snap, crackle and then a dead computer. I replaced the power supply after 3 days and crossed my fingers. Computer came up but was slow going though the USB configuration in post. Taking about 2 to 3 minutes to get though the post and then load Windows XP pro.

Eveything seems to work except all my USB ports do not pickup any thing plugged into them. I have 4 on the back of the MOB and 4 extra on the case in the front. I uninstalled the USB controller, shut down the computer and started it back up. Found alll the controllers and installed them again but after they all were found it showed 3 unknown device when I checked in device manager. I did not have any usb devices attached or plugged in at that time. I then decided to flash the bios with latest version which went fine. No luck with the usb. Updated my intel chipset to the latest from ASUS. Uninstalled and reinstalled the USB controller. USB configuration now zips by in the post, no unknown devices showing up in hardware manager but the usb ports still do not detect anything when I plug into them. I have devices that need the USB ports.....printer, cd rom, zip drive, several thumb drives. ?????? Do not know what to try next except to reformat a HD, install windows and start over. Did not want to spend several days doing that if I do not need to. Anyone have any suggestion? (my profile has my computer specs)

Hello My power supply died about a week ago.  I know this because it gave me a 4 beep code.  I followed the troubleshooting instructions, and when plugged in with all the cables unplugged, the fan didn't spin.  So confirmed dead. I got the new power supply today, and I plugged it in with no cables attached.  The fan spun.  Power supply confirmed good. However, when I reattached everything and turned it on, I got the four beep code again.  Does this mean my system board is fried?  And if so, where on the board is the id so I can order another?  I have the intel dual core cpu if that helps any.  Not the Extreme, just the duo. Thanks in advance for your help.

If I unplug my Bluetooth dongle and Maxtor USB external HD boot up is almost as fast as before.
Is it possible that something fried when the P/S failed? The Bluetooth devices (keyboard/mouse) and the external HD operate normally once the machine is "awake".
I just had them check the tower for problems and they say nothing is wrong internally.

I am now in China. My W540 power supply stopped work yesterday. My machine is still under base warranty. What I can do now? It seems there is no IWS (International Warranty Service) here. I cannot understand why. Please help!

I am sure that you can located one in China for fairly cheep, especially since they are probably made there anyway, and then upon your return, have the original replaced under warranty.     Ask around, there must be a computer outlet somewhere that sells parts that can locate one for you in China.    It may be a knockoff, but it will get you by for your trip, just make sure the voltage/amperage match that printed on the original.

My system has 3 HD's. The SATA is an add on, with a sata pci card, just for storage. The 2 IDE's are setup for dual boot with XP Pro on both(C:drive & D:drive). One is more for gaming, the other is for everthing else. Everything has been fine for several months until my power supply burnt up. I had set up a dvd to burn when I went to bed and the power supply died during the burn process. I replaced the power supply and now cannot get my C: XP to boot completely. I can however boot to my D: XP and access my C:drive and all of its files as well as my SATA storage drive.

On bootup, I select the XP installation that is listed first which is my D:drive, all goes well and evething works. If I select the second installation which is my C:drive all seems well... It shows that Windows XP is loading but when it normally goes to the screen that allows me to enter UserName and Password all I get is a black screen and it just stays like that. No error or reboot... nothing.

Would really hate to reformat(take about 2 days) as I had just got it setup the way I want it. Since ntloader does come up and allows selection would it be safe to assume bootini is ok? Is it probable that the death of my power supply could have cause corruption to kernel32.dll? What say you?

A:Power supply died, 1 of dual boot inaccessible

Have you tried doing a Windows repair on the C: partition?

We replace the existing power supply (model no. L305P-01) with a new power supply (model no. N305P-06) and the computer will come on put we are not getting a signal to the monitor.  Are the two power supplies similar?  Really not sure where to go next and any help/direction would be appreciated.

These units should both work on a 755 Mini Tower.   The DL2032 battery may need replacement.
Take out all ram and it should beep low and slow.

Then add 1 ram stick.
Sort thru each chip one at a time which should be matching pairs of ram.

Just replaced a bad power supply in my HP m1080n Media Center. Computer turned on and said windows failed to load. Gave me several options, Boot normally, boot in safe mode, boot from last working configuration, etc... Tried all of these and sometimes the comp shuts off as soon as I make a selection, and sometimes i get all the way to the XP boot screen and the loading bar starts to move before it craps out. Tried the recovery disk but no luck there either. Any ideas?
Replaced original Bestec 300W PSU (part# 5187-6114) with 300W HIPRO PSU (part# 5188-2625) ordered from HP. HP was responsible for the part change, not me.

System specs are at this link... http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00213797&lc=en&dlc=fe&cc=us&product=426502〈=fe#N346
***UPDATE*** 6/26/09 11:52am
Now I'm thinking it's definitely a hardware problem. Slept on it, woke up, and tried to power on again. Computer came on, clicked start windows normally. Made it through the XP boot screen all the way to login. Logged in with password and it started to load... then shut itself off again. The only other thing happening that I've noticed is that all of my fans come on and stay on the whole time. Usually the case fan doesn't run constantly and only kicks on when I'm running programs that soak up a lot of resources (Photoshop and the like).

Hello -

My computer was suddenly not powering on. I replaced the power supply, and the computer booted up, albeit with 1 short beep followed by 3 short beeps at POST. I'm not sure what BIOS it is, but it is a 3-ish year old Asus motherboard.

The problem now is - it will boot to the Win XP login prompt, however it is completely unresponsive to my USB keyboard and mouse. Oddly, I believe it is providing USB power because I have another peripheral (USB MIDI synthesizer) hooked up that powers up just fine.

I tried pulling 3V CMOS battery, different USB mice/keyboards etc, no luck. Any ideas why the USB mouse/keyboard are not working after replacing PSU?

a few hours ago, my mom brought home a brand new Acer Travelmate 4603WLCi laptop. after connecting the AC adaptor to the laptop, I turned the thing on. it worked just fine, and the Acer ePower Management software showed 33% battery power and still charging.

I was playing Solitaire back then, only for like 20-30 minutes, when suddenly the laptop just died. plain died. without shutdown.

so I turned it back on, and it went back on. only for like a few seconds after the Windows XP splash screen showed up, it died again. this time, I can't turn the thing on again.

I checked the adaptor cable that connected to the laptop, it's plugged firmly. however, the 'battery charge' lamp did not lit. I disconnected the adaptor cable, tried to turn on the laptop, it didn't work. I tried removing the battery, re-installing it, then tried turning it on again, also didn't work.

so I re-plugged the laptop to the adaptor, and thought that it'd charge up. but after 3 long hours of (useless) waiting, it's still not showing any signs of life.

I assume that this is a power adaptor failure, because when you connect the adaptor to the laptop, the 'battery charge' light is supposed to lit and you should be able to power-on the laptop. but hey, if the adaptor fails, aren't I supposed to be able to power-on the laptop by just the battery?

well, that's all I can tell for now.
thanks in advance for any advice(s) given.

Acer Travelmate 4603WLCi laptop shut down

Hi Dhaninugraha:

The situation you described back then, now looks quite familiar to me.

The same happened to me last night. My Acer Laptop just died, just as you described. I did all the things which are common things to try to make it back working again...NOTHING !

How did you back then solve the problem. Did you find out what the failure was?

I would really appreciate any help you can provide.

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

A:Solved: Computer Won't Turn on, no lights, replaced power supply

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.

Some weeks ago, as I was about to jet off o'seas, my PC just stopped working. The monitor suddenly stated "No RGB Input" and then the system turned off. There was a burning smell!! I was just Word Processing at the time.

After reading this and other forums, I replaced the PSU, but no change. Pressing the power switch does nothing - no fans, no lights - nothing!

I have now returned from o'seas and of course no change. Following advice from forums, I have stripped the MOBO to just CPU, and tried shorcircuiting the power switch, but all to no avail.

There is power getting to the MOBO as the chipset heatsink gets warm/hot with power plugged in.

The MOBO and CPU are both new, bought in March this year.

AMD 64 3200
1 Gb RAM
nvidia FX 5200 graphics

Any suggestions gratefully received.


A:Computer just died - have replaced PSU

It sounds like when you PSU went it took your CPU with it. maybe the mobo is still good but it can be hard to tell. if the mobo is damaged it could trash a new CPU if you put one in.

3 year old Gateway computer running XP, shut off computer one day, it had been running extremely slow, went to start up next day, wouldn't turn on. Replaced the PSU and booted it up, now getting error message while booting up:

Pri Master Hard Disk: S.M.A.R.T. Status BAD, Backup and Replace.

I can hit F4 to boot up all the way.

Any chance this is related to the psu dying or just a coincidence the hard disk is now failing too.

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?


Go to Solution.

A:Power Supply Question - Can I use the 230W power supply with a W540?

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

I replaced the DC jack on an Acer today with a new one. When the laptop has the battery in the power LED shows a power source(unfortunately the battery is dead). When I remove the battery and plug in the charger to the new DC jack, no LED. Hitting the power button results in a flash from the power button light and power LED for an instant but no POST or boot. I tried different chargers as I have a few universals laying around so that's not it.....What's the problem?

A:Acer Aspire 5742 no power from dc jack, replaced it, still no power

Maybe not enough power on my acer laptop the charger says the output is 19 volts 3.4 amps and it runs fine without the battery installed, When I dont have the battery installed and the charger pluged in there is no indication that the changer is indeed plugged in and also when I turn it on I usually press the button just a bit longer to turn it on
