Computer powered down, will not power back on

Q: Computer powered down, will not power back on


System Specs:

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


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.


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!

Preferred Solution: Computer powered down, will not power back on

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

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

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

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.

Computer specs:
Asus M2R32-MVP Motherboard
Asus EAH3850 ATI Radeon Graphics Card
4 GB Kingston 667 Mhz RAM
dual 80 GB Seagate SATA HDDs
AMD Athalon 64 X2 6000+ 3.0 ghz Windsor Core
430W power supply by Dynapower

Let me know if anyone needs to know anything else. Thanks.

A:New computer that powered up at first, but will not power up now.

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

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.

Hi forum,

A couple of weeks ago, my Dell 1545 Inspiron would only have a blank back light only screen when powered on. On the third day, I took it to the Geek Squad. He hit the power button and what do ya know, it came on fine. Huh?
Well, now it's doing it again. I called the Geek Squad, and they said it sounds like a loop problem - bring it in.
Can you tell me what that is and why it is and if I can fix it myself? I'd like to save my $ and do it myself since I currently have no job.

Thanks so much,

A:Back light only when powered on

Sounds like a bad power switch to me. I can not believe geeks squad hit the power button poor practice to me.

Hey so I have had this computer for about 3 months. It has worked perfectly fine the whole time. I had a similar model, U530, before this that worked great (it broke because of an accident on my part) as well.  However, today I was watching the internet and it looked like the monitor quickly shut off for a second. I moved the screen forward slightly after it had come back on and the computer suddenly shut off.  It will not come back on. When it is only using the battery the power button will not light up. When I plug in the power adapter, the power button will light up and turn off every second or so, but nothing else happens, no fan, no hard drive spinning etc... Is there any other way to diagnose this? I tried the manual but there was no information on light patterns or any precautions if it will not turn on.  I've tried turning unplugging the battery and holding down the power button, but to no avail...

A:Lenovo Edge 15, suddenly powered off and not turning back on

I just ran into this exact issue on my U530 Touch. I was just sitting there using it, unplugged, but the battery not about to die, and it just turns off randomly. When I try to turn it on, the power button lights up for a split second in response to me touching it, but that's all that happens. I've tried both plugged in and not and neither cause much of a reaction. Any ideas?

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

Many Thanks

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.

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. It took me 2 days to post this hope it works!

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). Moreover, the battery icon has dissappeared from the toolbar on the right bottom. Any particular solutions for this?I tried downloading the Desktop Power Manager for this from https://support.lenovo.com/in/en/downloads/ds003852. The installation fails saying there's an older version already downloaded (see pic 2). I'm not able to find the older version also to uninstall it

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. The Link to the video regarding possible causes seems to be broken as well. https://support.lenovo.com/vidoes/VID100760 I'm realy pi... off spending half a day failing to fix it and unable to open a support case. RegardsChristian

Okay so my power cord was chewed up. And I fixed it. Went to plug it back in and my all in one will not turn on. The light where you plug it in in the back is on so IT is getting power. However it is not switching on. Anyone have ANY IDEA how to turn this on . It was working perfectly fine before. My life is on this computer and if I call HP again and get someone who just tells me to go to geek squad again I'm going to be (for lack of better words) possessed off.  Thanks in advanced!

I am using a D-link 4 port usb powered hub and occasionally get the message "power surge on port" and it disconnects it from the computer.

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.

Any help would be appreciated.

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.

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,

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? Or am I missing something? Thanks.

Hey, having a few problems with my pc (to say the least).

My pc won't boot up -
I turn it on, it brings up the purple packard bell screen, it goes through all the motions you'd expect untill the "windows XP" screen usually comes up..its just black..nothing there.
It will also not allow me to boot from my windows XP cd,so i dont know how to fix this!
Any Ideas?

A:The computer is powered up but XP will not boot

Boot to safe mode. If that works ok, then you know you've got a problem with the startup hanging at some point likely due to corrupt files.

Review the event viewer to see any errors or warning (system and applications).

Booting from your CD is typically a function of the BIOS? check to ensure your CD drive is selected as 'one' of the bootable devices, and it's BOOT ORDER is set to boot before your hard disk.

I hope this is not going to be a problem. I leave my computer on except when I go to bed at night so it gets its 8-hours of sleep. Normally I have my screen saver kicking in after 15 minutes of non-use. But tonight after I was away from the computer for about two hours, I came out to the computer room and the computer was turned off, except the computer light was ON on the tower case. I had to reboot (or boot) the hard drive, ran Check Disk and it booted up normally.

Power Settings show no power turn off modes to be in effect and all other operations are excellent. Computer is healthy and malware free. I wonder if we had some sort of quick power outage in the house or something? I recall this happening with my Gateway when I had it years ago. (A power issue in the house.) Will watch and keep posting.

A:Computer powered router

Well, if you rig up a cord that runs from the disk connector to the router's P/S plug, it should work. Those supplies are just DC supplies. Make sure you get the polarity correct, or it'll be a short experiment.

Radio shack has a variety of the connectors used on those P/S models, if you can't find an old wall-wart to hack the cord off from.

Hey guys,

I came home today to install a new monitor, did a reboot--but when I pressed the power button to restart the computer it would not boot. Just dead. There is power going to the motherboard because I can see the SLI LED turn on when the plug is inserted. I've tried a replacement power button that I had laying around but the computer will still not boot. I don't have another power supply to test if it's the cause (but the SLI led still turns on, even so could it still be the power supply).

Where do I start trouble shooting in a situation like this?

Hello. I encountered an odd problem yesterday, and I was hoping I could get some help as to why. I had turned on my computer, and a few seconds after, the computer had turned off on its own. I turned it on again, and the computer powered up, but there was no activity; no display, and the light on the power button also would not go on. Also, the "thinking light" (as I seem to not remember what it's called) turns on and stays solid. My computer has no PC speaker, so I'm unable to hear any beeping (if there would be any). I was able to determine that the RAM is not the problem (swapping, changing ram did not change anything). I'm in the process of testing other parts, but I was hoping that someone with some experience with similar problems could help me out. Thank you very much.

A:Computer Powered down after turning on, now there is no response

You need to post your system component specs. Motherboard; EXACT make, model and revision (if applicable). Processor; EXACT make, model and stepping. Memory; EXACT make and model. Graphics Card (if installed); EXACT make and model. Power Supply; EXACT make and model. Provide links to the components.

If the machine is a mass produced machine such as Dell, Gateway, HP, etc. post the EXACT make and model as there may be known problems with certain makes and models.

No one can diagnose a problem without knowing the EXACT components you used in the build or the EXACT make and model of a mass produced machine.

I have Powered usb hub

plugged with usb device like Android phone for charging. IT is also plugged into front of usb front of computer.
I have usb power hub plugged into ac adapter to ac outlet.

When I click My Computer icon on my dekstop of my computer there is flashlght icon searching for contents in My Computer and it cannot display the usual c drive, dvd-rw icons and others until I unplug the powered usb hub.

So does this mean the usb powered hub is draining power from my computer
so I can't even display contents of " My Computer ", like it freezed up ?
Is this normal or is there something wrong with my powered usb hub ?

I thought that by using usb powered hub this would have prevent it from happening.

My powered USB hub is able to charge android device. Though very slowly
even when plugged in with ac adapter.


A:Powered usb hub searching for contents in My Computer

The Flash light icon searching is the computer "thinking". The USB port is not providing enough power to get the devices that are plugged into the Hub recognized.
Plug the hub into the Back USB port of the computer, not the front as that port is weaker. Plug the power adapter for the Hub into a wall socket directly and not a surge protector or extension cord as this diminishes it's power.
Do not plug in any USB Mass Storage drives to the Hub (eg) USB HDD, Flash Drives, Memory card readers etc. Only plug in light USB powered devices like USB Keyboards, Mice, Printers etc.
If you continue to have problems, replace the Hub with a known good brand.

I dont know if this is in the right Forum as its a strange one.

Just before i was playing on Counter Strike and the computer crashed.

The power was still on, on the CPU, and also on the Speakers and Monitor.

But the Monitor isnt picking up the Computer, ive tried a different monitor but to no avail.

Ive basically just swapped all the wires over from the computer onto one of my old computers which im on now, and there was no problems what so ever.

So clearly its something wrong with the other computer, but it still powers up and is running, but just nothing appears on my screen.

Does anyone have any idea as to what could be going on.

I don't know much about the computer, since it is my sister's computer, but I can at least give you guys the basics. By the way, younger sister says there's no use in posting here, but I'm doing it anyway.

So, my sister has a seagate HDD. Recently, a month or so ago, she started having problems with blue screens. The computer would be fine after for a few days, or even hours, until it happened again. It eventually devolved to where it'd ALWAYS want to perform a check disc. We allow it to do so, but a LOT of files would come up as corrupt. And even after that, the computer would still not work.

We've done almost everything. We've done seatools multiple times, we've checked the RAM, and we even wiped the HDD to see if it were some kind of virus buried deep within the HDD.

The last thing we're trying is using a spare power unit that has more wattage than the one she currently has. If that doesn't work, I'll post about the results here.

But I would like instructions on what you guys need in case it doesn't work.

A:computer powered, but no boot screen or video

Shutting down immediately is not a good sign.You either strip down to the bare minimum and try to get to BIOS /or take your parts in for testing.
Did you use Thermal paste? Heatsinks are always hot to touch so hard to say if you burnt it. until you can atleast swap out some parts/test.

So I tested by telling it to sleep, and it goes back to the bios and does a reboot.

I have turned it to never sleep. But I would like sleep to work.

  I have a HP Pavillion 23 all-in-one desktop running Windows 8, I believe. I haven't used it in about 2 months. I powered it on today and started running updates it missed out on; Apple Itunes and Norton. I opened a board on Chrome during the process but got nothing. I saw my bookmarks there on the screen, but nothing came on the page- black board. All of a sudden, mid install, the computer sort of powered off. The screen went black for about three seconds, then on for three seconds, then off for three, etc, etc. The power light remained on as well as a power light on the back, as well as some internal lighting that could be seen from the vents. It made a sound every time the screen went black like it was powering off, but I could still see all the lights on. I unplugged it from the wall for a few minutes and tried again. It will no longer power on, but I still see lights on internally. Not sure where to go from here. Any thoughts or feedback would be greatly appreciated 

A:Computer was running updates and powered down for good....?

  I'd try over in the Internal Hardware forums for some more expert advice:  http://www.bleepingcomputer.com/forums/f/7/internal-hardware/ 
My only suggestion is to unplug it and hold the power button down for 30 seconds.  Then plug it back in and see if it works.
Good luck!

Upgrading from Windows Vista to Windows 7 RTM

Okay, so I accidentally hit the power bar switch as in place upgrade rollback started.

When I rebooted, it came up with a few * is corrupt, rollback cannot continue messages, and then was greeted with a command prompt window.

Then, I inserted the Windows 7 install disc and chose "Repair Your Computer". It said it was fixing some hard disc errors.

I tried to boot into the rollback again-no luck, just a command prompt window.

The corrupted data wasnt very important, just some YouTube videos.

Is there anyway to manually start rollback? Please help!


A:Accidentally Powered off Computer right as Rollback started--Please Help!

Why bother? The Win7 RTM (if it is the Release To Manufacturing) would only be functional for the next month or two, anyway. Just bite the bullet and get a real Win7 commercial version.

When you go to install that, it should search your hard drive(s) and tell you what volumes you have and ask what you want to keep.

  I have a HP Pavillion 23 all-in-one desktop running Windows 8, I believe. I haven't used it in about 2 months. I powered it on today and started running updates it missed out on; Apple Itunes and Norton. I opened a board on Chrome during the process but got nothing. I saw my bookmarks there on the screen, but nothing came on the page- black board. All of a sudden, mid install, the computer sort of powered off. The screen went black for about three seconds, then on for three seconds, then off for three, etc, etc. The power light remained on as well as a power light on the back, as well as some internal lighting that could be seen from the vents.

Every time I power down my PC, it says "Installing update 10 of 16" and will never get past 10. I have left it on for 5 DAYS and it did't get past it. I have tried everything simple, such as restarting it, and it won't budge. This wouldn't be a big problem, because I don't really need those updates, but whenever I try to install something, such as Photoshop, it gives me an error saying "An installation is already in progress" and will not let me install what I want to. Does anybody know why this is happening, and how I can fix it?

I believe your firmware is corrupted, I would just backup important files and FDR it...

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...

I wanted to know if there has ever been a case where one has designed and/or created a fully-functioning computer(processor, memory, some form of screen display, and/or RAM)that is handheld and battery-powered(like a cheap version of a computer).

I want to know if it's ever been done and heard of officially(from scratch, meaning no pre-made parts were used, no "wiring" business ... all parts were developed manually and/or put together on a circuit board as well).

If this has never happened, is it legal to create one yourself and sell it, manufacture it, and/or get it copyrighted and patented?

I am talking no "major" OS here, no high-technology software, and no modern-age hardware.

Just one battery, one miniature processor at over 50MhZ a second, only about 8-28MB of RAM(no permanent memory storage), and a display device and adapters to blit just tiny applets made of 4 or 8-bit pixels(ones that are never stored to any disk drives, and that only run when the machine is on, and all data lost when off).

Something simple like that, doable by maybe one or two people manually and individually.

Has it ever been done ... and how hard would it really be to assemble all the parts?

PS: This is assuming the person(s) are very skilled in electronics(engineering, too, possibly), computer programming, technology, and hardware. Or at least somewhat skilled.

Computer seems stable and then will randomly BSOD-- Doesnt seem to be consistent with what im doing. A few of the BSOD's came after a 'error memory reference line' or something like that.

Computer is new, I installed drivers with supplied disks from motherboard manufacturer (asus). At first I thought it was the memory because Id read people having issues running 1866mhz ram with their Asus 990FX sabertooth, so I let it 'auto clock' and it chose 1333, But im still getting BSOD after that, tried adjusting voltage with no success either.

Please help, its very frustrating.. If I need to reinstall windows that is not an issue, I just need to stop the blue screens.

While working on a paper, my son's laptop indicated low battery. He immediately closed the screen and ran to get his charger. After plugging it in, the charge light was orange. He tried turning it on and the wifi light came on orange before going off again. We followed directions for hard reset and while no battery the charge light was white. It would not power on. This laptop is just over 1yo.
