Computer frequently shutting itself down.

[Rorym865]

So my PC is randomly shutting itself down, and rebooting after a few seconds. This is happening several times a day right now. At first I thought it was my CPU overheating, but I was monitoring my temps and it happened when it was only at 55 degrees. Oddly, although I game a lot, it seems to happen more often when I'm not gaming, and it seems to happen more often when I'm using the internet intensively, such as Youtube streaming or connecting to a game on CS:GO. Anyone got any advice? I'm currently waiting for an order on a new CPU heatsink and PSU.

My specs;
Windows 7 Pro x64.
Intel i7 860 2.80 GHz
Nvidia GTX 760
8GB RAM
ASUS motherboard (can't remember the model)

Sometimes the cause is the power company. Try plugging it into a surge suppressor.

It's already into a surge surpressor.

On another note, a new PSU and CPU cooler has not sorted the problem. Any further advice?

Look at the RAM. Try it in another machine, or run your system with only 1 stick installed, and than the other stick to isolate the issue.

I've already tried a RAM diagnostic. I'm fairly sure it's not that.

Another update; just happened again as I was about to reply to this, and when it rebooted, I got a BSOD, this has not happened before. When it rebooted from that, it went into system repair, and after it checked for errors it said that it couldn't repair the problems automatically. My system has rebooted fine now, I'll try to send you the dump files when I get back on.

EDIT; just shut down again. I checked the dump just before it did and it said the BSOD was caused by hal.dll.

EDIT: Ok so the rebooting happens in safe mode. Happened while I was doing a virus scan.

 

[Rorym865]

Ok so I've spent the last two days intensively troubleshooting. Here's a status update.

I've ran memtest86 and all tests were passed.
I've unplugged all nonessential hardware.
I've plugged the PC into a different power socket.
I've run DSKCHK.
I attempted to run two virus scanners from booting them from CDs, but my PC shut down, although it was fine for the memtest, and stayed on for an hour in the BIOS settings without shutting off.
I used the command prompt on the Windows 7 disk to scan for errors. None found.
I've switched out my mouse and keyboard.

Despite all this, the problem still persists. My PC can no longer stay on for much more than 15 minutes. Anybody got anything?

There is a wide differential for spontaneous restarts, and the cause can sometimes be elusive. This article I linked to below presents an organized way to try and find the problem.

I've literally tried everything on this list. Some more than once.

 

[digitaldoc]

These kinds of things are usually related to power supplies.

Did you try a new PSU from a name brand manufacturer?

Also, inspect the motherboard for any burnt marks, or leaking or blown capacitators.

if none of this pans out, the only solution may be a new rig.

 

[Rorym865]

The new PSU is a Corsair CX750M. I've intensively checked all the capacitators on the motherboard and checked for burn marks. But the PC seems to run in fine in safe mode (with one memorable exception, but now it's fine in safe mode).

 

[digitaldoc]

Can try to RMA the new Corsair, maybe that is the issue. Did the problem start when you installed that?

 

[Rorym865]

No. Like I said before, I replaced the old PSU to this one in an attempt to fix the problem.

 

[digitaldoc]

With a new PSU, than the issue is most likely the motherboard. At this point, I would suggest a new motherboard, RAM and CPU.

 

[Rorym865]

But how can it be the motherboard when it stays on in safe mode?

 

[digitaldoc]

If it really is stable in safe mode, than it may be a bad Windows install. Have you tried reinstalling the OS from a newly formatted hard drive?
