Q: computer died / power supply replacement

2 days ago the power outlet that my computer was placed into was kinda half exploding. And the "lightning protector" that was attached into it died. I was trying to connect the computer to a different power outlet , and the computer won't turn on.
Not sure what happend... So Idk what to do... Should I buy a new power supply and see if everything is ok? Or just give the computer to some lab and have em to "make it work" ??

Preferred Solution: computer died / power supply replacement

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.)

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?

I`m afraid it does sound like the psu has gone bad.

However, the only way to tell for sure, is to try another psu, and hope that`s all it is.

Recently I replaced the power supply in my computer and then my computer refused to bootup. When I try to bootup my computer just turns on, and nothing else. My monitor screen doesn't even get a picture which I'm assuming means that it isn't getting a "signal". The monitor remains black with nothing ever showing up (not even the text during the bootup screens) and the little light on a monitor that indicates that it is "on" just flashes like they do when you shut off your computer and forget to turn off your monitor. So I replaced the video card with a spare one. Same problem. I've used a different monitor. Same problem. And I have also used a different harddrive. But as you guessed it. Same problem.

I've reseated all my Ram, the CPU, and all of the ribbon connections about 10 times to ensure they did not come loose during the power supply change. Still nothing. As a last resort I reinstalled my old power supply system (which was working but old and NOISY) and it never helped.

Any suggestions? I'm at my wits end.

Thanks for any assistance. I need an adult drink.....

Oh those Best Buy geeks...
My parent's pc died on them and they took it to get serviced...3 weeks later, it came back with a new power supply, but the computer is awfully, awfully slow (it takes 10 minutes from.startup to load internet explorer). Factory reset has done nothing...did they touch something they shouldn't have?

A:Computer slow after power supply replacement...

You would have to ask them for a list of that which they did.

What brand, model, model # PC, or same information for the motherboard?

Computer specs would be helpful.

Which ;power supply was it: brand, model, model #, wattage? Same for now?

If you aren't happy, take it back & have them install a new power supply and politely insist that they demonstrate it to you before you accept it back.

Start the computer, note time from start to desktop appearance or log in screen appearance.

Start the computer in safe mode & do the same.

To start in safe mode, start > run
type: msconfig
boot.ini tab
put a check in "safe book"
exit without restarting
Shut down.
Turn on.

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?

A:Power Supply Fan 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?

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

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?

I have a Lenovo Thinkcenter i7 M92 that worked a while ago and when I turned around to work on another computer, it apparently turned off and now the power will not come back on. The power button wont even light up, nor will the lights where the network cable plugs in. Have tried different outlets, different power cords. I am thinking it is a power supply issue but I cannot find a power supply to order. Any suggestions would be greatly appreciated.

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

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!

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?

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.

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.

Recently the fan on my 600 W Cooler Master Power supply started to make increasingly loud noises. Upon investigation I found that the fan was locking up and then fighting to spin. I tried dusting down the system but had no luck in getting the fan to function properly. So yesterday I went out and purchased a new 650 W Antec Power Supply to replace it. I powered down my system, shut off the power supply, and removed the power cable. With an ESD strap tethered I documented the connections, removed the cables, and replaced the Cooler Master with the new Antec PSU. I then powered the box back up heard it post, figured it was fine and put my monitor back on it.

This is where my problems begins.

My system configuration is as follows:

motherboard: nforce 6801 sli
vid card: 8800 GTS
HD: two 76GB raptors in a RAID 0 for my OS
HD: two 500GB 7500k drives in a RAID 0 for storage
PSU: 650 W Antec
OS: Windows XP

When I power the box up all fans are active, the hard drives spin up, the mother board posts normally, and displays the "FF" status on the motherboards LED indicator signaling a normal boot process. The BIOS runs and I see it detect my two RAID stripes and it indicates that they are healthy. It gets to the boot from CD check and goes to a blank screen. It does not progress any further.

I am not of the opinion that the old PSU somehow damaged some system components as the actual power output was fine and my system functio... Read more

The only thing I can think of is you maybe unseated something a bit when reconnecting stuff. With the power off of course go through and reseat all the power connections, data cables, and add-on cards.

Any reason you didn't just replace the fan in the PSU rather than the entire PSU? Maybe put the old one back in temporarly just to see if it works still.

You can run any retail ATX power supply in the 410. I would recommend getting a modular PSU so that you only connect the wires that you need and put the others away until they are needed. This will help with not getting a clutter of wires that block the air flow.

A:Gateway Power Supply replacement

Sounds like there is no signal from the video card. How far along in the POST does it get? I am also not sure if Gateway uses standard ATX power supplys, you may need to get one directly from Gateway. Compare the pinouts from the old PSU and the one you just put in and see if the voltages are all the same with the same number of pins. This would be the connector that clips onto the motherboard.

I had some intermittent shut downs before the power supply finally totally crapped out. I have an HP Pavillion. I first bought a 750 watt supply from Tiger direct, but it wouldn't fit in my case. BUT, I did hook it up and make sure that the computer started up and ran ok. It ran fine. NOW, to replace that, the only thing I could find that would fit was a 350W diablotek. My problem is this, Now, when I hit the power button, the power supply fan turns on, but nothing else. When I turn it off, a power surge spins the cooling fan and the cpu fan.
The side note would be that when I was putting in the power supply, the heat sinc was in the way. When I pulled it out, I didn't realize that the cpu came out with it. I jacked up the cpu when reinstalling the sinc. I bent some prongs. I have replaced it with the identical cpu and still have this problem. Any ideas??

Laptop spec: HP530, Model HSTNN-C29CCeleron 1.73ghz1.5gig Ram,Windows Vista Home Basic. Last year I started having trouble with my HP530's power supply. At first it was occasionally not charging the battery when the laptop was running. This would mean that the battery would drop to zero charge and the laptop would suddenly switch off. The problem got worse until the point where it would on sometimes charge, and only if the laptop was turned off. I put the problem down to bad capacitors in the charger and decided to get a replacement. I got an official HP replacement from the High Street. The part number for this was: 463552-004. The part looks completely genuine, very much like other HP chargers my friend's have. I plugged it in to my laptop and it worked great for two days of very moderate use.. Then, on the third day, I plugged it into the wall socket and switched it on to get nothing. There was no light on the laptop to indicate it was charging and the icon on the Windows bar did not even show that the charger was connected. I tried it with a different power supply to wall socket cable, and it stroll did not work. At this point I switched off the plug outlet at the socket, disconnected the laptop power plug from the laptop and removed the plug from the plug socket on the wall. After I had removed the wall plug and it was well clear from the socket, my hand touched the two non-grounded prongs on the plug and I quite a big el... Read more

A:Failed HP530 replacement power supply

Yes they're not so good at fiability - all their cheap or main-stream products (laptop, printer) I bought from them dissapointed me faster then the competitor's, in the same amount of time. They sell a laptop 20-50 dollars less than others (similar specs), but on the long run you loose, because the product fails faster.Never bought expensive HP stuff, so I can't say anything about those.

I replaced a busted power supply in my old XPS 420 (with a MasterCool MasterLite 600). Everything has seemingly gone wonderfully. However, during the replacement I had to remove the heat sink from the CPU to get to the cables. I've never really installed heat sinks before so I got some thermal paste a put a dot tried to put the heat sink back on and it didn't fall into place. When I removed the heat sink I noticed the paste hadn't covered all the CPU so I added a bit more to make sure. Then was successful the next time putting everything into place.
I'm really concerned I might have not done it correctly so I installed speedfan to check temperatures. For the CPU I'm getting temperatures of 80degC (just posting this post). Which seems high, but I remember checking speedfan a while back and have a faint recollection of the temperatures also seeming high before. Also the GPU is at a similar temperature and I didn't touch that.
I'm just wondering should I pull the heat sink off and do the thermal paste again or is this a non-issue and these computers just run that hot normally? 

A:Dell XPS 420 running hot (??) after Power supply replacement

I would redo the heatsink application, with Arctic Silver thermal compound.  Fully clean off the old thermal compound from both the top of the CPU and the bottom of the heat sink.

The power supply of my three year old M900 desktop is making loud humming noises, so I figured I'd try replacing it. The Lenovo web site tells me the part number is 54Y8934, which I found listed here: https://lenovo.encompass.com/item/10629681/Lenovo/54Y8934/ Seeing as this is an older system, this particular part number isn't available anywhere. And the "compatible" parts listed on the Lenovo site aren't, either. Can someone please suggest a suitable current replacement?

I usually leave my machines on permanently as they are set to download and install updates overnight, only switching off the monitors. Went on holiday and turned everything off but on my return the XPS would not respond to the power button - green light on the PS is on, but dim, amber light on the motherboard is on. Reseated the power cables, no change. Jumpered the green cable on the 24pin connector to a black one - PS fan starts up, but still no boot up. I suspect the PS is faulty but I am having difficulty locating an exact replacement - proprietary ones do not seem to have all the necessary cables.
I have found a 'Dell DW002 H750E-01 XPS 630 750W 24-Pin Power Supply' online - can anyone say if this will work in the XPS Studio 435mt?
Or can you suggest an alternative?

I created a topic not long ago about my power supply getting ready to die on me. I thought I would get as much out of it as I could but I went ahead and replaced it with OEM Dell power supply 350W a few days ago. It wasn't hard to swap out the old one and put the new one in but trying to get the CMOS battery out was a chore unto itself. I took a picture of the inside configuration and wrote down where everything was connected so I would get it all back together right. When I got the everything hooked back up and plugged it back in to start it up I got an amber light on the power button. It turned on anyway and when it did I got the infamous "Diskette Drive 0 failure" screen. That's not a big deal and I fixed that in the BIOS controls. I also had to reset the date and time. Here's where it's getting tricky. I can't get either optical drive to read anything. Before they were working fine. The system does recognize both the DVD ROM and the DVD RW drive and says they are both working fine. When I put a disk in they start spinning normally but the Windows dialog box asking me what I want to do never comes up. I tried to do a systems restore and got the dreaded "An error has prevented windows restore from working" box with the red X. I wonder if something is wrong with the registry? I know I have both the optical drives connected right. One is plugged into SATA 1 and the other into SATA 4, just like they were before. I can't figure ... Read more

Hi, I am new here
Anyways, I have got this Dell Inspiron 660s which has power supply blown and I am thinking to buy a modular power supply (I am aware it might not fit inside the box). I am also thinking I may add a graphic card to make it a gaming or video editing station. (Haven't decided any specific graphic card tho). 
My questions are,
1) Is it possible (and/or recommended) to use modular power supply for this pc?
2) If yes, how can I choose and what are the key factors should I consider while buying a modular psu? 
Model name  L220NS-00
Printed information on PSU:


+5 V ~/15 A
+3.3 V ~/10 A
+12 V ~/18 A
~+5Vaux ~/3 A
+5 V & 3.3 V SHALL NOT EXCEED 100W
