PC shuts off suddenly after hours of use

Q: PC shuts off suddenly after hours of use

Hi guys,

I'm just a newbie and don't know how to mess inside my PC.

I just want to ask what problem my PC might have. My PC is old, but it is the only one I have. Lately, after some time of using my PC, the graphics went crazy with big pixels and the resolution was messed up. When I tried to print, the output has gone crazy as well. Then all of a sudden my PC shut off. When I tried to restart, it shut off again immediately.Today, as I tried to start again, everything seemed to be fine, but again after hours of using the PC shut off again. I worried that I might be hurting my PC since the problem still persists.

Fans are working.

Specs

Pentium 4 (2.8 Ghz)
1.5 GB DDR1 RAM
320GB SATA HD
Board: FOXCONN 865A01
Bus Clock: 133 megahertz
OS: Windows XP Professional Service Pack 2 (build 2600)

I really need my PC for my upcoming school finals and projects. I'm desperate, please help.

Preferred Solution: PC shuts off suddenly after hours of use

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.)

After a few hours I suddenly have a BSOD.
I used to have it a few days ago when I bought some new RAM. But this was after 5 minutes.
Then it was because of the RAM and I returned it and got two new.

Now I have it again and did the windows ram test and this time it gave me no errors.
I have added the dumb files.

I also did WinDBG:

Hello Peets, Welcome to SF

First off if your OCing in anyway stop, return everything to stock settings for the purposes of testing

If you havent already, fill in your system specs so we know what we are dealing with
System Info - See Your System Specs

Run some basic hardware tests
RAM - Test with Memtest86+
Disk Check (windows based check)
Hard Drive Diagnostic Procedure (bootable disk check)

Not sure what you have been doing and when so i just ran your last three dumps from today and they are all 0x1A memory management and as you have just put new ram in that has got to be the starting point, run memtest for multiple passes to see if any errors are found or take out new ram and see if crashes still happen

Looking at dump i can see all the ram is recognised but is it all compatible

I think I know the cause but wanted to check before opening her up.

Symptoms - The laptop spontaneously shuts down after around 2 hours

The power source makes no difference. It happens on both battery and mains.

Cause? Probably over heating, maybe due to dust etc

Remedy? Open up and clean the fan...............

Am I thinking correctly?
 

A:Laptop shuts down after 2 hours

I suspect so
However, is it always around the 2 hours - or does it vary
i would suspect overheating on a laptop to e slightly different - as it will depend on what the laptop is doing - if the fan is running and how fast
Also what sort of surface the laptop is on

Do you notice if the air from the vents is very hot ??? compared to normal running ?

in the last few days, after 7 or 8 hours of use, my computer seems to slow down, stop functioning and shut itself off.
Or else, when I come back to it after being away several hours, it has shut down, without closing the programs properly.
The screen is black. I think the power is still on, although once I found the power surge bar shut off!
Is is difficult to boot up again, but once I power it up again, it boots without any problems, and runs fine, until it slows down, stops working and fails again.

The ambient temperature is cool, and the hardware diagnostics show no problem. No viruses or malware detected.
It's a stand-alone Dell dimension 8250, Intel, Pent 4CPU 2.66 GHz and the OS is XP Pro 2002, SP3.

I wonder if it is a Power issue. I have shut off standby and hibernate because they used to give me problems.
I don't have a special UPS installed.

Any help appreciated.

A:after several hours, slows down, shuts off

If you found the power surge bar off, then I need to ask, is there a reset button on it? And did you have to reset it in order to get your computer back on?

I have this really strange recurring problem with my dell xps laptop, and it started with me sending it into repairs to replace the chipset, so I wonder if it has anything to do with that. My computer functions fine, it does not overclock or overheat at all according to the diagnostic tools I have checked, and is otherwise an extremely functional machine, aside from the fact that it crashes (no BSOD, no automatic restart, just sudden shut down with no warning, losing me all unsaved work) EXACTLY (this is the interesting part) every 2 hours. And when I say exactly 2 hours, I mean pretty much to the minute. Any process explorers I used inform me that there were no noticeable spikes around the time of the shut down (or should I say crash) and I have rigorously tested the battery pack and power cable to ensure this is not a power issue (which would make little sense anyway, with the crashes happening at precise 2 hour intervals). it could be running one chrome window, a video and a chrome window, or zero significant system processes at the two hour mark, the crash comes all the same. did a little research and apparently this is a common complaint for windows 7 RC systems in 2010 that have not been properly activated, hence windows activating the bi-hourly shutoff. Funny thing is I have windows 7 home premium, an activated and completely legal version, which has been functioning well for 3 years until this time. it really is getting sort of maddening, and my laptop repair place ju...

Welcome to the Forum kaziska.
When your repair shop replaced the chip set for your motherboard it could of changed how Micorosoft sees your motherboard.
That could cause a activation problem.
**You could take it back to the repair shop and explain this and ask for help.

About a month and a half ago my parents and I finally broke down and got wireless internet for our computers. Since my mom has a laptop and so do i we thought it would be nice we could just use those instead of fight for the main computer.

For about a month or so it was working great and we loved it, but a couple weeks ago it started turning off on its own every two hours or so! The box will still be on but we cant connect to the internet on ANY of the computers!

A:Computer shuts off regularly every 30 minutes to 3 hours

Sounds like a thermal protection kicks in. Sounds like your machine is overheating under load.

Do you have hardware monitoring software running so that you can see what your CPU/GPU temperatures are, fan speeds, voltages, etc.? This would be invaluable to help you rule in or out thermal issues.

I myself use a non-free product named Aida64 because of its highly regarded capabilities and customizations, which provide both a concise onscreen display using minimal real estate, as well as an optional flyover-help for its System Tray icon that displays whatever you want it to display (I don't use this myself, because I prefer the always-visible OSD updated every 4 seconds).

Hi there,

When I turn it on again after it shuts down (regardless of sleep or hibernation), it says (paraphrased) "Windows was not shut down correctly, please choose: Normal boot, Safe Boot, etc." I've searched google and these forums but to no avail.

Any suggestions on where to start looking for a solutions?! I'd like to avoid a re-installation if I can...

The cause of your problem is a driver that I am not familiar with it is

Hi there everybody. Lately I've built up my own computer. I am kind of expert so there shouldn't be any nab problem like mounting something wrong or placing wrong cables in wrong places but I have this problem. My pc runs very smoothly and powerful but after a period of gaming (like 1 hour of gtaV) my pc suddenly shuts down. It gives me no warning at all. I checked the temps and they all seems to be normal when the power off happens, so I think it couldn't be an over heating problem. This happens only when I "make things hard" let's say. The first days that this happened the AI software told me there was low voltage but now that doesn't happen anymore. But that's strange assuming I have a KCAS 600w.

PSU: KCAS 600w

I've been struggling with this for months and am at my wit's end. Any help anyone could offer would be greatly appreciated!

Basically, without warning, my computer, for no apparent reason, shuts itself off. No shut down. It simply shuts off, as though the power had been disconnected. (It might be worth noting that on starting it back up again, chkdsk doesn't run.)

At first, I thought it was a random occurence and likely a hardware problem; possibly the Power Supply. However, my MoBo is set to power up the computer after losing power and, after one of these unexpected power downs, the computer doesn't start back up until I hit the power button.

I've also started to notice a link to downloading. Namely, if there's multiple downloads going on, it seems to trigger the problem. It shuts down almost every night, which is when I've got utorrent scheduled to run, and I've been able to trigger the problem reliably by initiating multiple downloads of podcasts in iTunes. It also seems to happen sometimes when web pages are taking too long to load.

It's probably important to note that the computer functions perfectly otherwise. I can tax the system with the latest games or a heavy set of video transcodes without incident, so I'd have a hard time believing it would be a heat problem.

Based on suggestions from others, I have tried replacing the RAM and Network Card, but neither has had any impact on the problem.

A:PC Shuts down suddenly without warning

I'm not an expert by any means, but I guess there's no harm in having a bit of (possibly helpful) input...

It could have something to do with a faulty hard drive...I had something not so long ago where I had a lot of damaged secotrs, and copying things between disks would restart my computer (and sometimes never let it start back up)...

Have you got a spare drive you could test? Or if you have multiple drives, set the other 'good' one to the default download location and try to induce the problem.

I dont know what anyone else thinks of this...it could be completely wrong, but I guess there's no harm in trying!

I turned off the hyper-threading function on the P4 and that stopped it for a couple of weeks but now its started up again.

Once it just suddenly restarted itself, but 99% of the time it will just shut off.

Every time it shuts off, I have to unplug it, wait for a couple of seconds then plug it back in. A couple of seconds after I plug it back in it will power up again on its own.

I'm not sure if it's the ram, power supply, software or what. What could be the most likely culprit?

Thanks and let me know if you need more details.

My notebook computer has suddenly shut off three times today.

This has never happened before, except during times of cpu intensive activities,
such as video transcoding, where it has overheated.
...Then I bought a nice expensive cooling pad and it has never suddenly shut off since (until now).

The notebook did not feel that hot after any of the three times it shut off today,
and the cooling pad was turned on the last two times.

How can I figure out what the problem is?

We can also check the memory and Hard drive .....

Bad memory will cause system shut down...
for memory you can use Memtest86 http://www.memtest86.com/
or Microsoft Memory test http://oca.microsoft.com/en/windiag.asp

and also bad sector on HD may casue that also...

Hey Techspot, I'm hoping you can help me out with a little problem I've started experiencing. I got a Lenovo G555 just last year, and everything's been going great with it so far. However, as of about a day ago it decides to start shutting down without any warning whatsoever. It seems that this happens at random also. Some times I can keep the laptop on overnight (I like to have videos playing while I sleep) with no problems, and other times it snaps off after not even 5 minutes. Thus I can't really finish a scan with avast! or malwarebites. I haven't done anything out of the ordinary either. I don't know if it's really overheating because I keep it in a similar environment as my Toshiba laptop that has remained on around the same amount of time with no overheating whatsoever. I'm running Windows 7 on my Lenovo.

EDIT: I thought that my problem was in fact overheating, so I cleaned the fan area with some compressed air. That seems to help a little bit, but my computer still has a tendency to shut down randomly, just a lot less frequently. I checked the temperature with SpeedFan, and upon startup my core temp is as high as 80C, then cools off to about 60C when I'm doing nothing. The thing that worries me is that SpeedFan can detect no RPMs from my fan. Fan1, Fan2, and Fan3 all show 0 RPMs in the program.

Hello All,

I will appreciate if you can help me solve this problem.
I noticed that whenever I type the word antivirus, mcafee, antispyware in Internet Explorer or Mozilla Google search, it closes the windows automatically.
The McAfee antivirus is not responding, it is not even let me uninstall it.
I got to ran the HJTInstall.exe and I am attaching the logs, so with your expertise you can give me more light on how to troubleshoot this issue.

Thanks in advance.

Hi Everyone,

Computers never cease to amaze me. Just when I think that the computer is running "the way it should be", the damn thing restarts on me. It happened a few days ago while playing Madden 2003. It happened this morning, while printing a picture, I decided to close Paint Shop Pro. For some reason, I am leaning towards this being a video card problem. More specifically, I think there is a conflict between the video card driver and several programs on the computer (i.e. graphic intensive). It has always been my understanding that a computer is SUPPOSED to remain ON until you tell it to TURN OFF. I hope someone on this amazing board can HELP ME OUT!!

Thanks In Advance,

A:Computer Shuts Off Suddenly

Hi,

I'm assuming that you've confirmed that your CPU fan is working properly? (in case it's overheating)

Check out this site....if you don't have this driver, then try downloading and installing it:

http://mirror.ati.com/support/infobase/3985.html

I know that the specific error they mention doesn't really apply to you, but it might help your problem.

You could also disable your computer from automatically restarting with system errors. Right-click on My Computer, go to Properties, then Advanced, then Settings (under Startup and Recovery), then take the checkmark off "Automatically Reboot". This is probably what's causing it to reboot....while you're working on something that deals with graphics, and the system generates an error, it automatically reboots.

These are just a couple of suggestions.

Hi!

Sometimes my laptop suddenly shuts itself down, as if id just cut the power.

This usually happens while playing Crysis, is my computer getting to hot?
Im currently using WinXP, and it happens all the time, after about 20 minutes gaming. I used to run Windows Vista, and it happened only twice in 5 months. Anything I can do?
 

A:My laptop suddenly shuts itself down

My first question to you is this: do you notice any intense heat coming from the underside of the computer? Try playing the game in your lap, and feeling for heat (don't get yourself burned though!).

Also, what type of laptop do you have? (brand and model #)

In the past Sony Laptops were very known for overheating.

Greetings-- my previous problem was wonderfully solved here, so am hoping help with new problem will be successful.

This past week I've suddenly developed a problem where without any warning the computer will shut off. The 'power' button on the PCU will go to an amber, and will not respond to repeated pressings. The only way I'm able to get it back on again is to cut the machine off at the power strip, then press the power button. I've run some various system scans, and nothing turns up.

I am using Windows XP, have a Gateway computer, and have NO CLUE about what is going on. Many thanks for your thoughts and suggestions. Please let me know what more information I need to provide for consideration.

THANKS,
MOL

I've been struggling with this for months and am at my wit's end. Any help anyone could offer would be greatly appreciated!

Basically, without warning, my computer, for no apparent reason, shuts itself off. No shut down. It simply shuts off, as though the power had been disconnected. (It might be worth noting that on starting it back up again, chkdsk doesn't run.)

At first, I though it was a random occurence and likely a hardware problem; possibly the Power Supply. However, my MoBo is set to power up the computer after losing power and, after one of these unexpected power downs, the computer doesn't start back up until I hit the power button.

I've also started to notice a link to downloading. Namely, if there's multiple downloads going on, it seems to trigger the problem. It shuts down almost every night, which is when I've got utorrent scheduled to run, and I've been able to trigger the problem reliably by initiating multiple downloads of podcasts in iTunes. It also seems to happen sometimes when web pages are taking too long to load.

It's probably important to note that the computer functions perfectly otherwise. I can tax the system with the latest games or a heavy set of video transcodes without incident, so I'd have a hard time believing it would be a heat problem.

Hey guys,

I have a serious problem. I bought a new computer lately, it is superb but it has one error. Everytime i start my computer it shuts off after an undifined amount of time. It doesn't cleanly shuts down windows or something it just roughly shuts off. I did run a memory check, i build in another cooler for my processor and it didn't change anything. Sometimes it happens when i'm gaming, sometimes it happens when i don't do anything so it is a hard problem to analyse. When i am in safe mode it doesn't shut off.

These are my specs:

Asus 8800GS graphic card

I hope you can help me!

I would make sure your drivers are up to date and try a system restore if you have a restore point. Also, you might be able to find our more about whats causing it by looking at the event manager for dump files. Otherwise if its not a big hastle for ya i would consider a reinstall.

Hi,

My other computer suddenly shut down while i was playing a game. Then i smelled a burning odor. I tried turning on the computer again but it wouldnt turn on so i opened the case and felt the hardwares. The power supply and the harddrive were hot.

What happened to my computer? how do i fix this?

Thank-you.
 

A:Computer suddenly shuts down...

have a look and see if you can see anything burnt on the motheboard.
powersupplies and HD are HOT - how hot - remember they do run very hot hence the fans.

when you turn on - do any fans spin up or lights come on - if not its likely to be the PSU.

you could try disconnecting the PSU from the MoBo and other devices and then switch on and see if fan in psu runs.

otherwise you probably need a meter to check if the psu is working.

whats the make/model of the PC and then maybe someone can advise more on parts etc.

Windows XP, SP2

1)
While I am using my laptop suddenly computer shuts down. It shows a blue screen with some details of the error. But before I could read it, computer restarts. After restart, sometimes it may function normally and sometimes it would keep shutting down. I have to turnoff the computer completely for few minutes and then it would start working normally. This can happen at any time, there is nothing specific about this behavior.
This is happenening for 2-3 months now. Then it struck to my mind to check the log files of the system. So I checked system log files in computer management. It showed "iaStor" error there.

Whats this "iaStor" error ? Is that the problem for this kind of behavior ?

2)
Secondly, the pointer on the laptop freezes for few seconds quite often and then its released from the frozen state. When I am trying to click on a link or trying to scroll down, the pointer or grabber sign freezes and then it gets released after 4-5 seconds. Whats this behavior due to ?

I did uninstall and reinstall the windows xp, but still it gives same behavior for both the issues.

thanks

I'm from India. I bought a HP 15-ay106ne laptop through my uncle in Abu Dubai on 01-01-2017.After a week I noticed that it didn't charge to 100% it reaches 99% only. After 15 days I noticed that it suddenly shuts down when the charging reaches 15% without any notification about plug-in. After few days it shuts down in between 15% and 20%.Now it's shutting down in between 36%-40% of charging. I found that the battery backup is also not good. Original backup is 10 hours but my laptop gives 5 hours of battery backup.I gave my laptop in to a HP service centre and they said it has a hardware problem. In India the spare parts are not available so please go to Dubai with your laptop.I preferred to buy it in Dubai because of its international warranty. But now they are not going to help me out of this problem.Please help me to get my laptop in good condition. And suggest me how to decrease the cycle count.

I was recently having issues with the LCD backlight on my Dell XPS M1530 laptop. So I took it to the tech guy who fixed the backlight issue. But, now I get sudden shut downs while I'm working on my laptop. The screen goes white for a second before it shuts off by itself. Could it be an issue with wiring inside which the tech guy messed up? Or maybe the heat? because I notice the shut down when mostly my laptop is resting on a wooden table for about half and hour. Any advise?

Does your laptop have the Nvidia GeForce 8600M GT installed? If so your problems are very likely a result of the nVidia Defect (I have recently had a refund on a laptop I boughgt in 2007 because of this), have a look here http://www.nvidiadefect.com/ for info, it's a very helpful website.

Lately, my computer has been shutting itself off suddenly, followed by a loud high-pitched constant tone, which lasts until I turn the power off on the power supply. When I turn the computer back on, I get a blue screen that says there was an error and the system has been shut down. If I leave it off for about 10 minutes and turn it back on, it will come on fine, but eventually shut off again. A friend of mine mentioned that this may be a motherboard issue, so I'm just wondering what everyone here thinks.
