Recently I've been having lots of trouble with my computer randomly restarting while I'm playing games. I can usually play for about 30 mins to an hour before my computer suddenly restarts without warning, no blue screen or anything. Here are my specs:

Motherboard: Gigabyte GA-Z77-D3H 1155
Processor: Intel i7-3770 3.4GHz
Memory: 32Gb G.SKILL Ripjaws X (4x8Gb) @ 1333 MHz
Graphics: EVGA GeForce GTX 680 2Gb VRAM
Storage: 1TB Western Digital Black
Power Supply: Rosewill 1000-Watt Bronze Series 80 Plus
OS: Windows 7 Professional 64-Bit

I've replaced my thermal paste, reinstalled windows, and rand a disc check, but none of it has seemed to work. I've used RealTempGT and EVGA Prescision X to ensure it's not a heat problem (neither register much more than 60 deg during gameplay), and emptied my disc out to make sure I have ample space. None of my parts are even overclocked. The computer is about a year old, and I really don't want to have to bring it to microcenter.

Games I've tried that seem to cause the problem:
Metal Gear Rising: Revengeance
The Witcher 2: Assassin of Kings
Shadow Warrior
Space Engineers

Usually the issue in the case is the power supply. This is the first most common issue. The second most common issue is the capacitors on the motherboard. In newer computers I have not been able to find these at fault. More likely on a new computer it's the CPU voltage regulator on the motherboard.

Suggested course of action: Replace power supply.
If the computers still continues to reboot, replace the motherboard. This should resolve the issue fully if the power supply does not.

In the event that you are overclocking and the computer is rebooting, the issue is likely the voltage regulators on the motherboard unable to supply the current, overheating, and thus causing a reboot. The temperature of your voltage regulators will not appear in any software, unless you have a very high end motherboard.

Thank's for the insight, coovargo. I don't particularly feel like shelling out for a new PSU quite yet, so i'll wait for more responses. Also, it would be nice if you could remove your double post; it's crowding the thread a bit. I'll add information about my power supply to the OP.

Well, I wouldn't go spending money on new power supplies and motherboards just yet. Just set your BIOS to defaults and see if that doesn't allow you to game without restarting. I'd say if you have success with that, you need to tone down the overclock.

Seriously, that was it? I just started an AVG scan some time before starting the game up; did your computer restart as abruptly as mine after the scan had finished?

An anti-virus software will not abruptly bring your computer to a black screen. No one said he had to spend any money on a power supply. He bought it from microcenter. It's probably a new computer by them. If he went down there and explained it to them they would probably send him away with a new PSU and to come back if the problem happens again. That is, if he did buy it from microcenter. BIOS settings will not cause a computer to abruptly shut off unless a thermal safety shutoff is turned on, which would be incredibly obvious, even to a novice in BIOS. That's also a high-end board feature anyways. Power supplies are cheap anyways.

A full HDD will not cause a computer to abruptly shut down to a black screen.

I still recommend you find a substitute power supply to test the issue with. You are using a high-draw GPU. I fix nearly a dozen computers at my shop a day. Some of them have this issue.

Well, i'll uninstall AVG just to be sure; I can keep Malwarebytes as a replacement. Also, I did not buy this computer from microcenter; I picked up all the parts off newegg and constructed it myself. Also, I highly doubt it's a power-draw failure; my PSU generates 1000 watts. I've added all relevant information to the OP.

Yes it will. I left my computer on downloading "Educational" torrents, came back and the computer was off. Checked the event viewer and "read on"

What i meant was AVG doesn't just randomly do it. There is a checkbox under scheduled scans to reboot after every scan. Just uncheck it. I had to check the event viewer and there it was plain as day AVGscanprogram,forgetwhattheycalledit.exe has initiated a planned shutdown.

On an unrelated note,
"A full HDD will not cause a computer to abruptly shut down to a black screen."
If you run out of hard drive space and you run out of RAM the computer will blue screen. May even be a black screen if you are lucky lol.
Not saying this is what is happening, but it would happen if the hard drive was completely full and windows couldn't use virtual memory.

Mine didnt reboot it just shutdown. AVG may have both options in the list of things to do when your virus scan finishes.
