My gaming pc restarts at random times (Not heat related)

Iamthewalrusss · Mar 28, 2014

My custom built gaming pc restarts at random times, gaming or not. It's usually 2 hours, some times 15 minutes or even 8 hours it's been going on for about a week now and I can't stand it.

My specs are:
Intel Core i7-3770K 3.5GHz Quad-Core Processor
Asus P8Z77-V PRO ATX LGA1155 Motherboard
Corsair Vengeance Pro 16GB (2 x 8GB) DDR3-1866 Memory
Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
EVGA GeForce GTX 780 3GB Video Card
Cooler Master HAF 932 Advanced ATX Full Tower Case
Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer
Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit)

Try this:

1) Go into power management

2) Click on "change plan settings"

3) Go to "change advanced power settings"

4) Scroll down to "Hybernate After", click the +, and select "never"

DonnyTechMaster :

It is already set to "never"

Hmm, have you checked your device manager for errors? Sometime that can cause random shutdows because a part in your PC could be malfunctioning. If there are none, then you may just have a faulty piece of hardware.

Nope no errors, Just today my pc shut down and wouldn't come on without shutting down in a matter of seconds. Then, I turned it on and a message came up from my motherboard on the monitor saying "Overclocking Failed" when I don't even overclock.

Thats weird, check your bios and make sure that your CPU clock settings are at default. Sometimes your motherboard will change the settings to what it thinks is best, and that might be what's causing problems.

The motherboard had the cpu on turbo mode, not sure if it has to do with overclocking, but i disabled it. Mainly because I'm only using the stock cooling for my cpu

Okay, that could be the problem, Give it a few days of use with the new settings, and post if it happens again.

The entire day yesterday my pc was working perfectly fine, until today when it restarted right before i got to the main menu of Fallout 3. What happens is the pc shuts off, tries to come back on, but keeps shutting off before it gets to windows. So, I put the power switch on the back of my pc to off then back (Tries to come on, shuts down in half a second) I do the same thing again, it won't come on at all now. Then I try it again 1 minute later, stays on the rest of the day, has problems until next time I turn it off.

It could just be your PSU failing. A good way to test this would be to remove it from the pc, plug it into the wall and turn it on. Let it sit for a while and monitor it to see if it cuts out. Even if it only cuts out for a few seconds, that would probably be enough to shut the pc down.

NOTE: even if the PSU doesn't cut off when it is removed from the case, it could still be the fault of the PSU. It could be that it simply isn't putting out enough power for all of your components, and is causing your components to fail.

Yes, i did the test and my psu is shutting down and starting up. Even when nothing is plugged into it. I had to keep my motherboard plugged in to get power by the way. I don't have a spare psu hanging around. My psu is the Corsair AX760.

I'm a bit confused, are you saying that it is starting up and shutting down properly, or do you mean that it is shutting down randomly.

I'm saying when I did the test it started up then shut down suddenly. Which is what it was always doing, which is bad. Then I plugged everything back in and it came on perfectly. Stayed on for the rest of the day. My pc works when it wants to work. I contacted corsair about a replacement psu. It shipped today.

Oh OK, I'm glad to hear that you found the problem!
