Power supply died, backup won't work.

Q: Power supply died, backup won't work.

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 been the only problem I have had with it thus far.

I'm not particularly tech savvy, but by my power supply burning out like it did, could it have short circuited or damaged the motherboard/any of my other parts?

Preferred Solution: Power supply died, backup won't work.

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 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

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?

I built this new computer about a month ago.

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?

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.

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.

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

A:Need to replace an overheated power supply that died for my ...

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.

We live on a dead-end road out in the bushes in a 3rd-world part of Kentucky; needless to say, sudden violent power outages are a frequent part of life.

As a result, I spend more than my share of time and frustrations in setting our computers back to rights when one of these frequent blackouts messes things up in some way or another; so, sometime back, someone on here suggested I get a device that protects from sudden surges and shutdowns.

I thought I would put this on my Christmas wish list.

I have just bought a new custom-built computer and Dell monitor as well as installing a new Brother printer.

A:Got advice about buying uninterruptible power supply (UPS) / battery backup?

conceptualclarit said:

CyperPower model I found at Office Depot. 625 VA, 375 watts

My new custom-built computer :
My new monitor :
Dell Computer Corp E2414H 24" LED LCD Monitor
AC input voltage/frequency/current 100 to 240 VAC/50 or 60 Hz + 3 Hz/1.5 A (Max.)
Printer :
Brother MFC-7340
Power Consumption - Sleep/Ready/Copying
10W / 75W / 460WClick to expand...

If you plan to use the full capacity of the new computer's power supply, your UPS will need to supply the about 650 watts (not volt-amps) for the computer plus another 30 watts for the monitor (monitor specifications).

The MFC-7340 uses laser printing. Most UPS manufacturers do not recommend running a laser printer from their products. Laser printers use quite a bit of power (460 watts in your case) plus have a large inrush current that draws a lot more watts when the internal heater cycles on. It would almost need it's own high power UPS to use during a power outage.

Throw in operating the older computer at the same time and you need to add the wattage required by it, plus any second display, to get the total wattage rating you need for your UPS.

You also need to consider how long you wish to run the computers during a power outage. Some UPS units may only supply their full rated power for ten minutes or less. You're probably looking at a UPS that supports adding external battery packs if you want extended run times.

Good morning everyone,

What about that new ram too that's being releaed. Would that work too?

Also do you guys think it's time I upgrade this instead?

A:will this power supply work with my pc?

Sure, power supplies are pretty universal aside from some big box OEM systems that use odd sizes. But do you really need a 1000 watt power supply? Do you have multiple high end graphics cards?

As for RAM, most DDR3 will work but the upcoming DDR4 will not.

You probably have the Intel i7-980 Extreme Edition processor.

A:after power supply install hd will not work

The BIOS & PSU have no relationship as regards hardware detection so that's not the issue.
One possibility is that you bought an incompatible PSU - does it have leads & cables identical to the original PSU and have you connected them all up to the correct places? (it doesn't matter if the new PSU has some extra cables not required for that system, just as long as it has at least got cables and plugs identical to the original one and they are connected properly).

Also, did you ensure that the new PSU's output is at least the same wattage as the original, and preferrably more?

Greetings! My computer is running XP Home Edition, an AMD Athlon 1000 chip, with 512MB of memory.
My power supply burned out (300 watt ) while I was working in Excell. A friend of mine took it to her friend to fix it. A new power supply was installed (400 or 450) , an Abit KT7A motherboard, NVidia440 video card, and a new case with 2 usb ports added to the front. When I got it back and tried to go online, the internet worked fine and did connect, but when I opened any of 3 different browsers I got the message SERVER NOT FOUND. I tried my email and got the same message. I left the internet on for about 5 hours and then I heard my email notifier say I had mail. I ran in to see what was going on and the browser was working. When I shut it off later and tried to get online again, I got the same message as above and have not been able to browse since. I changed my modem and still get the same message SERVER NOT Found from the browsers. I use Opera, Firefox, and tried IE also. I've never heard of anyone having this problem. I checked my internet with a dinosaur computer and it works fine.

My son's Lenovo Notebook's power supply plug doesn't work anymore, and he has only had it for 2 years. He bought one of the newest and most powerful ones, and thus a very expensive version i.e. a bit above 1,000.00 UK pounds. The same happened to my Lenovo tablet. Two years after I bought it the power supply plug went dead. I manage to make it work again about 3 weeks by replacing the cord, but then it died again despite trying with 6 different cords. I have also tried to blow clean the plug with a can of pressure air. Didn't help. After googling the issue I can see many Lenovo customers have the same problem, and that it has been going on and on since 2011 perhaps even earlier. So I assume Lenovo has addressed and solved the problem by now. I went back to the vendor with my tablet to have it repaired, and the response was that it would be too expensive to repair, and that I would be better off buying a new tablet. So I did. Do you think I bought another Lenovo? Of course not! We are never gonna buy any Lenovo products ever again. I still have the old tablet, though, and would be very happy if could be repaired. The same applies to my son's portable pc, he needs it for school projects, so it is quite urgent that his pc can function again asap.

I'm in past my abilities on this one. Can a 400 W Antec ATX 12V power supply, unswitched except for an on/off switch on the back, work on an old Amptron motherboard, a PC that came with a switched power supply?

Background: I'm having strange system crashes plus intermittent "blackouts", the PC turns off and on by itself (no flicker from the desk light attached to the same outlet). I'm thinking maybe I need a new power supply and go to my local computer store. They have no switched power supplies, which is what the PC was built with 5 years ago. I got the Antec, thinking it might work, get home and put it in the PC. Nothing. Completely dark. The on/off switch on the back does nothing, no fan, no power.

It looks like the power supply is looking for a signal from the motherboard to go "on". I may just need an explanation of how switched vs. unswitched power supplies work.

A:Can an unswitched power supply work on a MB that came with a switched PS?

I don't think you're talking about switching vs. non-switching powersupplies, a switching powersupply is one that can auto-detect whether the input AC voltage is 110V or 220V. I think you mean that your old computer had an AT powersupply, and you want to know if it can work with an ATX one. Your motherboard must have both AT and ATX powersupply connectors on it, for your new one to even fit. An AT powersupply has a shielded powercable leading to a switch that goes behind the powerbutton on the front, it hooks up to that with 4 wires. An ATX powersupply relies on two pins on the motherboard being shorted (they get connected to a powerbutton on the front that doesn't carry current, unlike the AT powersupply that carries a dangerous mains voltage line through the middle of the case). It sounds like you have an AT case, I would suggest transferring your motherboard to a new ATX case and hooking the front powerbutton on the ATX case to the power pins on the motherboard, they will be alongside the hard disk LED, reset, power LED etc. pins. There will be a 2pin plug named "power" or "ATX power" or something like that to make this connection.

Can any ATX replacement power supply work with a hp pavilion a6000 desktop

I had recently installed a new power supply (850 W) because my old one was starting to make whining noises that made me think it was dying. After installing it and plugging everything in I turned the computer on and everything was working aside from the graphics card. The processor fan was running, the main fan was running, but the graphics card fans were not going at all...

I swapped out the card with another (actually better) card and it worked (only problem being I don't have a proper adapter for the card to use my current monitor with.)

Is there any reason something like this'd happen? The card is PCI-E and I tried all 4 PCI-E cables for it and none of them powered it up...

A:Installed New Power Supply, Graphics Card Won't Work

My initial thought would be a problem with the card itself as you said you put another one in and it worked. However, I assume (from later in your post) that the other card 'working' was assumed because the fans started on it and they don't on your original card?

Do you get any output from the original card to the monitor, you only mention about the fan not working?

I sure need your help on this! lol. I have a home built computer. It is about 6 years old.
The OS is XP Pro, 2 gig of Memory, 200gig WD hard drive, Asus P5AD2 Premium Motherboard. Here is my problem. I replaced the Power Supply that was in it. I replaced it with a Zalman Heatpipe Cooled 600 Watt Power Supply. All I did, is unplug the old PS, and remove it, then, put in the new one, replugged it, turned on my computer and it acts like
it is going to come up... the PS fan is running, a green led light on the motherboard is on, but nothing shows up on the monitor. The monitor power is on, and I have checked the monitor connection to the compter and it has a good connection. So, I thought maybe the new PS was defective or something, so I decided to just put the old power supply back in it, because it was running just fine before, I only wanted to replace it because it was kinda noisey and I wanted a quieter one. After putting the old Power Supply back in, I powered up the computer and it now is doing the exact same thing that the new Power Supply did. The computer lights and fans are all working but nothing is showing on the monitor. I checked to make sure that the cable and power hookup on the hard drive that has the OS on it is connected good, and it is. I am lost on what to do next. I hope someone here can help me please.
Thanks very much,

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

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.

My SSD died and I want to know if any issue I would have restoring the backup image to a mechanical drive and then back again when the replacement drive comes. Thanks

A:SSD Died and I Need Some Help Restoring Backup Image

If the drive is dead, how are you going to get the image off of it?

Assuming you already have an image backed up, as long as you're aware of alignment, imaging to a HDD for now and back to the new SSD shouldn't be a problem... I always prefer to do fresh installs, but many do imaging without an issue...

I've been getting ready for a disk replacement after 7 1/2 years but the disks arrived too late to avoid anything problematic.

My external HDD gave a cylindrical error while reading some data in a program so I knew this was going to be the end of it. I tried to avoid running chkdsk and suffer so I had time to backup but my harddrives won't come in the mail until tomorrow. I tried to navigate to the directory that gave the cylindrical error and half the files couldn't be found, as expected, going back the entire file tree containing couldn't be found either so I tried running chkdsk anyway and just go with it but it couldn't "load a RAW partition", so the boot sector of the drive failed, without thinking I shut off the drive and turned it back on.
Big mistake because now nothing loads at all.

I tried chkdsk /R, which did not work.

I downloaded testdisk and I'm running an analysis right now, its working, but extremely slowly (has been running for more then a day and is at 1%) and often gets stuck on a cylinder for several minutes to half an hour often resulting in a read error.

I have EasUS Partition Manager Pro 10.5 and HDD Regenerator as well if this does not help.

I'm not really familiar with testdisk, I never used it before, I did read the "manual" but that's only describes one scenario, mine already differs from whats on the site so I could use some help in how to fix this so I can access my data, copy and paste everything to the new HDD... Read more
