Computer crashing at random points while gaming

TheAsianTechno · Jul 24, 2014

Occasionally when I play games my computer will hard crash and automatically reboot itself sometimes it will appear to crash but take me back to my desktop. When it crashes my monitors display a blank grey screen and repeat whatever sound was last going on in my game. It seems very inconsistent as I could be playing for 6 hours straight and not crash or I would play for 20 minutes and it would crash. It varies from game to game for example Titanfall, Left 4 dead 2, and Dark souls 2 are victims of these crashes. My temperatures are fine (Rarely over 70 degrees) and my computer isn't overclocked and when I run furmark it never crashes. I've tested my RAM and everything seems fine with my sticks.
Specs: I5 3570k
GTX 670
Asus P8z77-V-LX
RIPJAW DDR3 8GB Ram
Several 1 tb western digital HDD
TX750w Corsair PSU

Sounds like GPU drivers or possibly PSU stating to head south (and the GPU getting starved). Make sure you have the latest drivers for GPU and also check your BIOS and mobo drivers

I have similar experience with BF4 ... I don't play it but my son does and he crashes consistently at stock settings whereas everything else plays fine at 4.6 Ghz / 46 cache / 2400 and SLI'd 780s at 26% OC (21% memory). I can run any benchmark for 12 hours and it runs fine.

You say temps are rarely over 70 ...what temps CPU, GPU or both ?

The 670 is not a big power draw at about 149 watts so your 750 TX PSU should be able to serve well for years but klunkers do escape the factory which is why they have warranty programs. Have you monitored your PSU voltages with OCCT or any other utility playing and seen any significant voltage variations ? Voltages on 12, 5 and 3.3 volt railes should not vary by more than 2.5% on a TX model

Anything in event viewer ? Note the time of your crashes and on next boot look in system logs for any unusual error or warning events logged at those times.

Check drivers versus latest on manufacturer's web sites, especially audio and video drivers. Install latest where ya find yaself behind.

Uninstall GFX drivers and all accessory drivers / programs related thereto , use a reg cleaner to wipe out all references to same, reboot and reinstall.

Do you have an aftermarket cooler and did you install it yourself ? I had one system a fellow brought in, drive me nutz.... on a whim, I loosened the cooler hold down screws and problem disappeared. He had overtightened and warped board causing a contact issue somewhere. Only thing that made me think of it is I had in recent months done rebuilds where the over tightening was more obvious and in one case board was actually cracked. Within 2 months we rebuilt that one too.

Thatz all I can think of for now.

I do have aftermarket coolers for my CPU and GPU but i'm pretty sure that I didn't overtighten them, I didn't even know that could cause problems and i'll check event viewer but for the drivers I am up to date on all aspects so it can't be that. Is there anyway to test if my PSU is becoming faulty? because I would much rather replace that than buy a new gpu

I also had this problem, the solution was to reset my CPU and GPU to stock speeds.

Yes, you can test your PSU as indicated above with OCCT by monitoring the voltages while running the CPU or GPU tests. Make sure to read the warning about the "PSU Test" as it's been known to fry lesser contenders.

In the OP it was indicated that " my computer isn't overclocked".

Main reason I know that is I typed the same thing and then when I went back and checked one of the other comments, saw that I had missed it 1st time thru
