Computer Powers Off

It does sound like overheating, or possibly a power supply problem. This laptop I'm on right now will do just that if it overheats. I don't think it has much to do with how much the processor is being asked to do.

Are you using a desktop or a laptop? If it's a desktop, try opening the case and cleaning the fan. If that doesn't work, change the fan.

If it's a laptop, make sure it isn't on a soft surface, such as your lap!!! Or use a table fan to keep it cool.

I used to spend time fiddling with my PC's. I learned allot by doing so. But I did end up spending time on fixing equipment instead of marketing etc. Now when a PC acts up, I just take them into the local repair store to run a quick diagnostic. It makes much more sense than trying to figure out what might be wrong.

Yes it could be the Power supply overheating, or a hardware issue. And even though you are scanning it, it could still be a virus not caught. Or it could be a recent update of a driver that is messing things up. You could try doing a system restore to an earlier date. But my best suggestion, go get it checked professionally.

yeah, backup what you need and reinstall windows back on it. Could be a virus embedded or nested somewhere that your antivirus and malware bytes is not detecting.

It could also be the motherboard that's slowly dying.

My old laptop did the exact same, it would randomly just cut out. Took it too a repair shop and was told the motherboard was dodgy.

I assume you are using a laptop? Are you plugged into the wall or on WIFI? IF you are plugged in, check your settings. It sounds like the computer is saving energy and powering you off.

The model and type of computer would help a great deal.
Usually the same family of computer would have the same
type of problems. The last time I had similar issues it
turned to be the fan on the video card that died and this
was messing with the power supply. I had to change
both.

So look up the model # for your PC and do a Google
search with the problem and you will normally come
up with something more specific than good guesses.

First off, automatic restarts do not always happen just because of a malware. It can be caused by a service (see services.msc) that failed to perform its intended function(s). If and when that's the case, it will execute three steps in order of priority. By default, "Restart the Service" is the first option. I am not completely sure what could have happened but it's possible that another application must have set either the first, second or third option to "Restart the Computer."

I am not just going to speculate in here. I just mentioned one of the gazillion possibilities that might have occurred. It is just not helping when one tells someone to do this and that without even asking for probing questions in order to duplicate or reproduce the problem.

Mike, I didn't invent the computer but let me see if I can help you on this.
Let me ask you some probing questions so we can isolate the problem (divide and conquer strategy).

1. When did this start happening?
2. What was the last thing you did before this problem happened?
3. Malwarebytes' Antimalware is not considered as a total security system for Windows. It runs on an on-demand request only. If you do have a security program that's currently installed (eg. AVG, Microsoft Security Essentials, McAfee, Norton), what is it?
Note: Windows Defender is not started by default in Windows 7.
4. What do you normally do before the computer restarts? Do you browse the internet and the computer restarts after a few minutes of browsing? Since you're a writer, do you write using MS Word and then the PC restarts after a few minutes? What application program do you usually run before the computer restarts?
5. Did you install Windows Updates before the problem happened?

If I was only your neighbor, I would have not asked you these questions. I will simply check the Event Viewer and we may find the culprit from there. But let me limit my probing questions with these five for the meantime.

The next time it shuts off immediately open the case and touch all heatsinks with your finger. If you can't leave your finger there for more than a half second because it's burning hot, a fan is getting stuck and the computer is turning off to prevent meltdown.

This should be suspect #1 if you are playing games or watching videos around the time this happens.


This is highly unlikely a software issue since it happens infrequently.

It is not the problem of over heating. as you said your Computer shuts down occasionally ( 1-2 days) therefore it can't be over heating.

I had the same problem. its your motherboard, actually when I diagnosed the problem there was 2 dead IC's in my motherboard which where dead. due to which the load can't be organised within the circuit and your system gets a inadequate power supply and hence shuts down. in 95% of the cases, its the motherboard which causes occasional shutting down.

I got it replaced and all was back to normal. hope you have you motherboard in warranty period

Did you check if your computer fan system is working well?

I once had the same problem with my laptop, in the end (because I was too slow to rectify the issue) my mother board was spoilt.

After that incident, I always make sure if I use a laptop it is with a cooling fan or elevate the laptop so that it doesn't overheat.

But if you suspect it could be a machine issue better to get it checked and get the parts replace asap.

If it is possible do a system backup of your computer first before sending for repairs.

Else if you are thinking of getting a new system you can consider using software to transfer files from PC to PC.

Wishing you the best of luck.

The OP needs to update us with better information or if he has gotten the problem resolved.

Hmm hmm. I think I'am the only one on the earth who has problems which are not normal or common. But when I searched for it I came to know it was motherboard and it really was. Might alter in his case
