Q: Computer randomly turns of

Hey I've been having this problem for quite awhile now, everynow and again seemingly random my computer will turn of completely then startup again. At first I thought it was a powersupply issue, but after getting a new one I ruled that out. Then I thought it was due to power surgers so I got a surge protector to rule that out. So now I have no idea. The shutdowns do not happen when the computer is under alot of stress. Sometimes I can leave my computer on for days and it will never happen. Any ideas?

Hello! I have a Dell inspiron laptop with a windows 7 OS. A few weeks ago, I had set down my laptop on my bed and had fallen asleep, only to awaken and see that it had turned off. I thought nothing of it then, believing it simply overheated but it's happened a few times since then. Today, I had set my laptop down on a glass table and I fell asleep on the sofa there, only to wake up four hours later with the laptop off. Again, I believed it was a heating problem but turning it on and going to the pool, I would return one hour later to see that it was off once more! It's strange, because it doesn't turn off when I am at it and doing something on the laptop but if I turn away form it, there is a chance that I may find it off when I return. It cannot be that someone is turning it off as I live by myself. Every time I turn it on after finding it off, it takes me to the Windows Error Recovery black page at the beginning.

Could this be a heating problem or something else?

Thank you very much!

A:Computer turns off randomly

Hello,

More than likely it IS an over heating issue started or aggravated by leaving it on the bed. That tends to block tightly the air ports in or out that vent the CPU and GPU.

The startup screen you note occurs after a crash so its not going to sleep or hibernation. You should check the power settings anyway and turn off any power saving features while your testing and switch to high performance. This should make the issue occur faster as well. Watch a movie or play a game to heat things up faster.

If that doesn't identify the cause let us know. If it does crash look to cleaning the vents with a vacuum, open the bottom panels and check for lint or dirty heatsinks and fan. if your lucky the thermal past is still good no balled solder issues.
Good luck,
Zen

Hi,

I am using an HP e-pc machine (which uses a small form factor motherboard) and recently it simply switches off with no warning what so ever. Seems to happen more often when running intense applications.

I'm unable to reboot it using the power switch, I have to manually unplug the cable, and plug it back in at the back to get it to turn on. It'll switch off in dos (in the bios menu) and in windows, no bsod or anything similar.

I thought it was a heat issue, however after ensuring the heatsink+fan were properly set, then leaving the case open and hainvg a second fan blow at it, it still turns itself off.

This is a pentium III machine, and unfortunately there are no temperature gauges in the bios, and I don't everest doesn't recognise any either. The power supply is an external one, similar to a laptop power supply design, using a 19v/3.16A.

I am not normally able to keep it running for over an hour.

Thanks in advance,

Louis.

Since you've determined its not a heating issue, it could be a power supply issue. Do you have another power supply you could test?

A family member has reported that her computer eventually randomly shuts off, often in sleep mode. I've run the followings antivirus programs: Norton Securty (the antivirus installed on the CPU), Norton Power Eraser, AdwCleaner (this found HKCU/registry/conduit), JunkwareRemoval, and MBAM. Besides the "conduit" line AdwCleaner found, everything else comes out negative.
 
So either this is a crazy virus or something with the computer itself. I caught the CPU turning off randomly. When I turned it back on, the screen saying that the CPU did not turn off right and "window error recovery" showed up. I chose to start up normally and Windows reported the attached picture file (I just took a screenshot of the window). I've no idea what minidump and the oher file is, but I'm guessing minidump has to do with memory.

I know there is a topic that addresses this already, but I have some computer-specific questions related to the procedure/advice that is given in the other thread. I have a IBM ThinkCentre 3.0Ghz machine that is randomly shutting itself off. It appears to be an overheating issue. The other post recommends checking the fans. I see two fans in there (they both work), but does anyone know how many fans there are in this machine (it's a tower). Is there a hidden fan that isn't working or is it just the two I can see? Second, if the heatsink has a thermal pad, do I still need to apply a new layer of thermal paste? Third, what temperature should a computer run at? The other post included a link to a diagnostic tool, but I don't have any benchmark for comparing my computer. Also, if the computer shuts down when it gets hot, how can I use the tool?

Thanks for your help!
 

A:My computer turns itself off randomly

computer shuts off randomly

Do you mean that if I just leave the computer sitting there after it has shut down, it will turn back on after 5-10 minutes? When the computer does its "I'm turning myself off in the middle of a process" routine, the mouse, keyboard, harddrive, all that junk turn off, but the power light remains on. Will it restart after it cools down? Also, when I try to restart the computer, it will get to the desktop, then shut down. It does get by the BIOS and loadup screens, though. Is this normal for an overheating issue? Finally, what kind of issues could it be with RAM? Are there any tests/diagnostic tools to check?

Thanks

Hello. I'm a new PC builder and only know the very basics. I just built a new computer and at ran into a few problems. My specs are:

I connected everything (don't know much about PSU, just connected them all, I'm a bit ignorant about the whole voltage thing) and at first it works fine. I let it load and do the disk format thing when installing XP and leave it on while I fell asleep. Few hours later the computer is off. I turn it on and it turns off a few seconds later with nothing on the screen. Tried turning it on around five times and the same thing happens. I leave it alone and look on the internet for some solutions and then tried again. The computer works fine for around 20 minutes and then shuts down again. I try again and then it shuts down few seconds later. I turn it on in the next hour and it lasts for 1-2 hours before shutting down again. I look online with people with similar problems and ones saying its the CPU, the other says its the PSU, motherboard or RAM. I don't know who to listen to.

Athough our HJT Team members work on hundreds of requests each day, they are all volunteers who work logs when they can and are able to do so.

Although we try to take DDS/HJT logs in order (starting with the oldest), it is often the skill level of the particular helper and sometimes the operating system that dictates which logs get selected first. Some infections are more complicated than others and require a higher skill level to remove. Without that skill level attempted removal could result in disastrous results.

What's the first step in figuring out what's wrong? It has two brand new 250mm fans. When it started doing this last weekend I thought it was overheating, so I got it new fans but the problem has persisted. What else can I check and how?
It's a custom built PC, originally built in 2009.
It's running windows 8.1 64 bit
AMD Phenom 9950 Quad-Core processor 2.60 GHz
8GB memory
AMD Radeon R7 370 Series graphics card
Seagate  1TB SATA HDD
MSI DKA790GX Motherboard
PSU 860 WATT ATX12V
EDIT: Looking in the Custom log reveals Kernel 41 errors. Tried to run use windows diagnostic to check the memory and it only got to 80% complete (no errors detected yet) before shutting down with another 41 error. This leads me to believe it's not memory since it had the error during the test, and my assumption would be the memory wouldn't be in use that way if it were attempting to check it, is this correct? How can I find out which part it is? If it's the PSU or Motherboard etc. IF it's a faulty PSU what do I need to check when buying a new one to make sure it's compatible to my motherboard?

Hi, I'll start with a brief description of my PC. It's a 2400XP with a 400W Q-tec PSU, running Win2K with SP4. I've got ZA free, AVG free, spywareblaster, spywareguard, adaware and spybot as well.

My PC was running fine until a wire stopped the fan from turning, and the CPU overheated a couple of times, and hence turned itself off after an audible alarm. I've sorted this out, and set the fan speed to max, but the PC now regularly turns off with no alarm. It even does it when I use a floppy boot disc and leave it at the A prompt!! Most of the time it turns off after about a minute, but occasionally it will run for a few hours.

Please can anyone suggest where I should look to sort out this problem, as it's driving me mad?

Many thanks in advance, Chris.

A:Computer turns off randomly

Sounds like a hardware problem. Could be the Power Supply or an issue with the Mother Board. Or you may have fried the CPU or a memory chip.

I would replace the Power Supply first and then if that doesn't fix it, test the Memory chips to see if they have any errors.

Hi, I am new to this website so I am not sure whether this is the correct forum to post this thread; but here goes.

I recently tried to install some new RAM into my computer and noticed a problem; basically it wouldn't work at all. So after doing a bit of research I found out that it wasn't the right type for my computer. So I removed it. ]

Everything seemed fine until about 2 days later when my computer turned off randomly, without me shutting it down. I thought it could be the computer overheating so I lifted of the shell and cooled it for a bit. Not the problem, even without the shell on it still turns off. I have changed my PSU cable and still not working.

I have a Fujitsu Scaleo P. Any suggestions?

Hi, ive been having this problem for a while but it is not constant. My computer will simply turn off randomly. Sometimes i can go for hours and hours of gaming and it will be fine so ive ruled out over heating as an issue. It was suggested that maybe a slot of RAM had become faulty causing my computer to turn off.

Today i decided to test my RAM by running high demanding programs hopefully causing my computer to switch off. Then i would take out a single slot of RAM to see if that was the problem. The thing is ive been running programs all day and my system hasn't shut off once. I know should be patient but to be honest this is taking the piss.

If anyone has had this sort of problem and could share some information on what may be causing the problem then please help.

Hi guys

I was wondeing if anyone could give me a explanation for why my computer randomly turns off after 30-2h of it being on? The computer will boot up fine, load all programs like normal - i can start a game or word doc and work with those for a bit but then the computer randomly turns itself off! It wont turn back on straight away unless i turn it off/on at the back and unplug-plug it back in.

Now, I've concluded from tests that it is not the PSU (PSU tester) or a temperature problem (I've monitored my CPU - doesnt go over 50C = but not tested the MOBO temp - case temp is about 40-45C).

My specs are: ASUS P4-800SE, P4 2.8GHz, 1 GB DDR RAM, 320GB HDD, 500W Coolermaster PSU, 512MB Radeon 1650PRO AGP, Soundblaster 5.1.

I was wondering it could be bad RAM or MOBO - how could I test each component exclusively? Does it matter that the RAM (2*512MB) are in slots 1 and 3 (of 4))?

BTW I installed GOW around the time this problem started but did a system restore...

Any help would be much appreciated and merry xmas to all
 

A:Computer Randomly Turns Off

Asus boards are usually pretty reliable but a visual inspection to check for damaged capacitors might reveal something - I have had the same symptoms before and it was either the main board or the capacitors in the PSU (Tested OK as well!) that caused the problem. Try another PSU if no fat caps on the motherboard - do NOT under any circumstances muck about with the caps in the PSU - there's almost enough volts in them to kill! No kidding....

Hello,
I have an HP Pavilion 15 that is about 3 years old. It has a 2.40 gigahertz Intel Core i5-4210U processor. 
 
Twice today, my laptop has, without warning, shut off completely. The only way to bring it back up is to plug it in, despite the battery being at around 30% or 50%. I had updated my computer in between the two shutdowns. I am not sure if it has anything to do with Windows 8.1 or not. If I could get help on this, that would be great. Have a good day!

A:Computer Turns off Randomly

It might not be any software issue. Laptop and its parts stop working optimally after a random time (generally 3 years or till end of your warranty). Also there can be any loose ends/ loose contacts. That's a general case though.
 
You can also try cleaning with CCleaner for any errors (just in case).
 
Check the battery health once. Go through the link if you don't know how.

Hey, folks!

My new computer (one month old) recently started turning itself off seemingly at random (while playing a game, surfing the web, etc.). At first I thought it might be a faulty PSU, video card or mobo, so I took my rig into the guys who built it for me and they replaced the video card. This didn't solve the problem. I took it back and this time, since they too were baffled, they kindly gutted my machine and replaced every part (or so they say) including the video card, mobo and PSU. In fact, they upgraded the mobo to a higher-end model as their way of saying sorry! Everything seems to be running a lot smoother and the shutdowns are happening a whole lot less often - only once since I brought it home from the most recent repair attempt. In my book, though, once is still one time too many.

I've done my fair share of research on the issue and advice on the matter seems to range from a bad video card, mobo or PSU to Windows XP being finnicky to a loose stick of RAM. Needless to say, I am stumped and so are the guys who built this machine for me. So, with that said, I turn it over to you - the real experts!

Help me, Obi Wan Kenobi! You're my only hope!

System specs (as far as Everest and my uneducated eyes will tell me) are:

OS: Windows XP (Pro, SP3)

I recently installed my hardware components in a new case along with a new hard drive and a new power supply unit. Since the installation everything seemed to be running smoothly, except for the fact that my computer shuts down randomly. When I play Far Cry 2 my computer shuts down consistently after about 20 minutes, and with casual PC use my computer shuts down after about 90 minutes. My guesses for this problem is that there is something wrong with my power supply, despite the fact that it got very good reviews, my motherboard is shot, or some component that is connected to my mobo is overheating. If anyone knows how I can solve this problem, that would be greatly appreciated!

A:Computer Randomly Turns Off

Yes JoeM076,
I would say that the Corsair is a great power supply! You have an Asus motherboard. Could it have been damaged by static while moving it into another case. Is everything snug and connected securely? What about properly cleaning the old thermal paste off and reseating the CPUs heatsink and fan. How are the case fans? Are they running freely?

Hi all

2 days ago I replaced my CPU from a FX6100 to a FX8350, last night and this afternoon I've encountered issues where the computer randomly turned off.

Last night I was just playing Train Sim, and all of a sudden the computer just turned off, no warning no nothing, just switched off, pressing the on button didnt do anything at all, although there was still a light on the motherboard so I had to remove the kettle lead, wait for the motherboard light to go out and then put it back in and turn the computer back on. I thought it was just a random thing and hoped it would go away. But a short time later it did it again while playing train sim.

I downloaded AMD OverDrive just to see the temperature of the CPU and it was saying anything between 50c-60c which quick look on google, people said was pretty hot, so I reapplied the thermal paste and added a little bit extra just to be on the safe side. Started PC backup and the temperature seemed to stable it self at around 45-50c, although when playing Train sim for example it would actually go down to 30c-40c.

The same thing has happened again this afternoon, again playing train sim, and a look at the temperature now, its about 57-59c. So maybe I'm thinking, it's still hot? Or maybe the fact that my power supply is not giving enough power to my system?

I've got a 500W PSU and had so for a few years with no problems, but upgrading my CPU makes me think that maybe its a PSU issue not giving out enough power? Is there a way to ... Read more

If the problems started when you swapped out the CPU, that is where I would be looking for the problem. You would have to get a Power Supply tester to make sure the proper voltages are being outputed.

Ok I've been having this prob for afew months.

My comp would just randomly turn its self off while I was playing. It was like someone just pulled the power cord out of the wall, and i could power it up strait away after it did it.
I replaced the PSU thinking it was underpowered and it seemed to fix it.....for only a few weeks and now it has started doing it again. My new PSU is 550w so i don't think its that.

I have a small feeling that it is overheating. In speed fan my first core says 19C but the 2nd one is 53C! is that normal? that is an idle temp btw.

And i can play Left 4 Dead for aslong as i want on low graphics but when i bump it up to MAX setting it will only last about 30mins....And it also seems to turn off faster on hot days

Plz help i have no idea what to do. This comp has been working fine for about a year, why would it start overheating now?

sounds like your infections did not get really removed so maybe you should try the following

Save HJTsetup.exe to your desktop.

Double click on the HJTsetup.exe icon on your desktop.
By default it will install to C:\Program Files\Hijack This.
Continue to click Next in the setup dialogue boxes until you get to the Select Addition Tasks dialogue.
Put a check by Create a desktop icon then click Next again.
Continue to follow the rest of the prompts from there.
At the final dialogue box click Finish and it will launch Hijack This.
Click on the Do a system scan and save a log file button. It will scan and then ask you to save the log.
Click Save to save the log file and then the log will open in notepad.
Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.

Basically whats happening is that the PC is just randomly powering down for no reason, just like sum1 pulling the plug on it, and i have to pull the power cord out of the back and wait for a few seconds to turn the thing back on. but its only doing it when i'm playing games on a reasonably high res? but its starting to get worse on the lower spec games aswell now? does any1 have any ideas as to why its doing thins? currently i'm thinking its either the power supply(which is about 2months old) the graphics card ( about 5months) or the ram (1stick about 2months and the other about 6). any information or any1 with the same problem? anything would b useful.

And sometimes won't turn back on for a while. At first I thought there might be a short in one of the connections inside, or maybe a dieing power supply. Those might still be true, but I remembered that this started after I told my computer to "sleep" after 3 hours. That is when it began randomly crashing. I've already turned off sleep, but the problem persists.

My computer will just randomly die. Sometimes when I hit the power button after this happens it turns on for a second, fans spin, lights come on, but it dies again before it even gets to the bios. Every time it has died it has been when it wasn't in use (i.e., when it was at its lowest level of power consumption). Games play fine. All my drivers are up to date that I know of.

Any ideas? I don't want to take apart my computer if this is a bug in windows.

My computer restarts randomly depending on how long in between the times it already restarted. if i haven't used it in a few days it works for a few hours and if it has turned of anywhere from 1min to 5 hours it only stays on for a few secs to a couple of minuets. I have tried replacing almost everything. Including Power supply, ram, hard drive, unplugging everything unnecessary(Video Card, Mouse and keyboard, Network stuff, just the power cord and monitor left in).

I'm 98% sure the processor is not over heating sense i ran programs to check the temp and it shuts down even if the the core and everything is below 35° and the processor is cool to the touch. What has me stumped is I can replace the hard drive with a spare one with Windows XP freshly on it and it will still restart. I have tried to disable all the network drivers installed on my computer.

Any suggestions or thoughts would be great! (Even if you dont think it could be the problem).

The computer has a 700w Power supply. (OCZ Tech)
AMD 6000+ Processor (not over clocked)
2Gigs ram. (A-DATA)

Okay, well my sister has moved out to Colorado and left her computer here. It seems to have several problems. After about 5 minutes of using it, it just shuts off. If it lasts longer then that, it starts to sound like a airplane about to take off. Then when i shut it down (on my own) it sounds like it is trying to start back up but doesn't actually start. It just keeps on making the noise unless i un-plug it. Any help would be great.

I know it is a Dell Desktop computer using Windows XP. I don't currently have it set up so i cant look at the information but i will do that tomorrow morning once i wake up. How would i find out more information about it though? As i said i'm not sure how long it will stay on for, for me to get alot of information.

Hey there.

After installing my new XFX 9800 I know have had this turning off randomly issue shortly after I got it. What happens is after a little while of playing (around the couple hour mark) my computer just turns off and doesn't turn back on again. Just before my computer turns off my graphics card's fan goes a bit loud. I did look this up and I figure it is a heating issue. So how can I solve this problem? Is there somewhere on my computer where I can check what fans I got? What fan should I get to support this card? And no this turning off issue has not ever happened before I got my new graphics card.

Hi Guys, my specs are as follows:

Windows 10
Just updated Power supply to: EVGA SuperNOVA 850 B2 80+ BRONZE, 850W Semi Modular NVIDIA SLI, 110-B2-0850-V1

The computer will turn off randomly. It will also turn off when I exit games on occasion(more likely to turn off than not). This happens without warning with no error message.
I have recently installed my graphics card, an upgrade from a 560(I think). I also recently added a 2TB HD, in addition to my 1 TB, and my 250GB that came with the computer.

I checked the windows log, and after each shutdown I see a critical error message as follows:

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Source: Kernel-Power

I believe this is a symptom more than a cause. I can't seem to find an error regarding the crash itself, however I don't really know what I'm looking for, so...

I have three theories, without a lot of substantiation.

1. Maybe it's my main HDD that contains the operating system. Should I try moving this to a newer drive? I did do a HDD check, and it says the HDD is okay, however it's 10 years old...

2. It could be the CPU overheating? I downloaded something to monitor this, and from little knowledge I have on the subject, it seems to be within normal temperatures.

8gb ram
1000 gb hard drive
Dell xps 8300
Nvidia 530 gt 1024mb
PC is 5-6 years old
I currently Have AVG antivirus and had panda few days ago - BSODs showed up with both.

Sometimes the PC would be normal for a week or two and then it would continuously crash for another week. And then this same cycle again (good for a week then crashes again for another... Etc)

After it started crashing I cleaned the PC from any dust (the vents were clogged). It stopped crashing for a month, then came back again. I monitored for temp issues, but it was fine unless I am rendering a video on Sony Vegas (got to 84C). At normal times temp was around 45 if idle, in the 50s if browsing the internet, and low 70smif gaming. I barely game - all the crashes occur when I am browsing (which is what I do most of the time)

Disable "Automatically restart" option
Click on the start and type Sysdm.cpl, hit enter.
Switch to Advanced tab and click Settings button of Startup and Recovery.
Deselect the Automatically restart option and click OK to exit.
Download and install all the updates from Windows Updates.

Also replace ESET with MSE from the link below and run a complete scan to make sure you're free of viruses.

Hello

So I have had a big problem with my computer. It does not happen that often but when it does it is really annoying and scary. My computer just shutsdown and a screwed up noise goes through the speakers and the fans goes sky high! It happened one time when I play crysis 2. I played it for like 5 minutes before it happened. I booted the computer up and then I had a look at my temps which where around 50C. Started up crysis again and played for like 10 minutes and it only went up to 70C. So it is not an overheating issue! What should I do?

Hey LeonPT, welcome to Sevenforums

First remove all non-essential cards from your machine, i.e sound, modems etc, etc.

Download burn and run memtest from PassMark MemTest86 - Memory Diagnostic Tool. This will test your PC's memory. Leave it running for a few hours.

Next

Download the manufacturers disk for your hard drives. Test and ensure that they are functioning properly.

Remove and clean all components contacts and clean the CPU fan and any other fans in your system.

Report back with results.

Sorry about wall of text but its a pretty deep problemThis problem started about 2 weeks after I built my PC. One day, it just went poof and turned itself off. 3 seconds later, it automatically turns itself back on. I went into my windows and turned off the setting that means it automatically restarts after power loss, but it will still turn on on its own. I managed to fix this issue for about a month by opening it up, just fiddling about (things like pushing cables like CPU power and mobo power) and then I unplugged it from my surge protector and into my wall socket. It was absolutely fine for a month, I could play the most intensive games, temps are not a problem and nothing would happen. However, a month passed and then one day it turned off and turned itself on again. I am stumped.My educated guess would be that it's the PSU acting up but I am not sure why I fixed it for a month. I have noticed that every time I open up the computer and fiddle inside, I seem to hold off the shutdowns for a week or a few days. I have run memtest for about 2 passes with no errors, and I have not yet seen it shutdown when not in windows. It hasn't shut down in safe mode or in the bios (however I havent tested it for very long)My motherboard was already replaced before the build as it was DOA, and I have run stress tests on the GPU and CPU. (nothing happened)Any help is greatly appreciated, my main question is why was I able to stop the shutdowns for a month, and why is it that... Read more

Based on your information, you may have an issue with your reset button. As you built the PC, you're aware of where that is connected to your motherboard. Please disconnect it completely and see if that makes a difference.
 
I'm not sure by your description if when you "shut down" the PC yourself, if the PC stays off. Could you verify that. I'm guessing that what you're describing is the PC is not shutting off, but rather doing a restart or reset.
 
You haven't indicated if the Windows is giving you any BSOD or other message, or if it just goes black, and restarts. Please provide that as well.
 
Let me know,
 
Kurt

So as the title says i was playing Diablo 3 and my computer randomly turned off. I had no idea why as i was always able to run the game perfectly and my system does meet the system requirements. I cleaned my fan on my computer of dust to stop it from overheating if that was the problem but it still shut off within about half an hour of my playing.

I have no idea why its doing this. I have been playing this game for about a month and never had this issue. My system meets the requirements and i have no other issues with the game. Does anyone know what the problem is here? I am thinking its something to do with overheating but it makes no sense to me.

Hi guys, not sure if this is the right forum to post this, but any help would be greatly appreciated!

Recently, my computer began shutting off instantly when I was playing any particularly resource-intensive games (specifically Space Marine). Initially I had guessed it was overheating, so I cleaned out all of the components in my PC and restarted, but I was met with the same problem repeatedly.

I had then assumed that the fault was with the PSU, so without any to spare, I ordered a new one. Upon arrival I put it into the PC, but it whirred noisily and smelled like burning. Clearly broken, I sent it back.

A few days later I got a new one, put it in the PC and all was good, the PC got past the boot stage and I booted up Space Marine again, but once more, it broke down and shut off instantly after a few minutes of playing.

I was pretty sure the power supply wasn't likely to have broken three times in a row, so I tried it in another PC and it worked fine. After that, I tried disconnecting each component in turn, ruling out (I think) the DVD Drive, BluRay drive, both Hard Drives and the Sound Card. I tried taking out my graphics card and replacing it with an old one of mine, an 8800gt, and the PC booted up. I was pretty sure that was fixed, because I could play games for a while with no issue. Eventually, however, it crashed again.

Interestingly, whenever it does crash, I can't boot up for a short while, the fans whir for a second and then nothing happens... Read more

Hello!

I'm looking for some advice and guidance.
I am not a technical expert on computer hardware. I understand the basics and that's about the extent of it.

My current PC is a Dell desktop/tower; it runs Windows 7; it uses an Intel Core Duo processor. It is a few years old (I'd estimate 3 or 4 years old). I plug my PC into a Belkin surge protector/multi-outlet device, which plugs into the wall electrical outlet.

My problem is that recently the PC randomly has been instantly powering-down and then a few seconds later powering-up again and rebooting. This happens twice or 3 times a day, on average. I have no explanation for it. I do know that it's highly annoying and I'm concerned and want to do something to fix this problem before any permanent damage occurs to my PC.

Last week, I searched the internet briefly for advice, and the two possible causes that popped-up in search results were: A) overheating, or B) issues with the power cord. Given that, over the past week, in my spare time, I have totally rerouted all the cords and wires behind my computer desk, to ensure that no wires were tangling, pulling, or weighing-down on the power cord for my PC. I also totally dusted out the cabinet and backside of the PC tower, and gently vacuumed the "fan" area on the back of the PC, to ensure it was free of dust and lint. I removed some random objects from the PC cabinet (CD's, mice, keyboard, etc.) to ensure that there was plenty of "ai... Read more
