Hi, a few minutes after I start a game my PC decides to restart itself. I have had the GPU for over a month and this just started to happen over the past couple days. Is it my power supply? Also I have the latest drivers on my graphics card. I though it might be a heating problem but my GPU and CPU seem to be fairly cool during gaming.

My Specs
GPU: Gigabyte GeForce GTX 970 G1 Gaming 4GB GDDR5 http://goo.gl/ioJq90

CPU: Intel Core i5-4670K Haswell Quad-Core 3.4GHz http://goo.gl/2HJwEw

HDD: Seagate ST310005N1A1AS-RK 1TB http://goo.gl/IkYnVV

Motherboard: GIGABYTE GA-Z87M-D3H 1.0 LGA 1150 Intel Z87 http://goo.gl/njWgF2

RAM: Patriot Viper 3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 http://goo.gl/k59j7V

PSU: Rosewill Green Series RG630-S12 630W http://goo.gl/s1mSHx

Case: Fractal Design Arc Mini Black High Performance PC Computer Case http://goo.gl/i1sOIG

Cooling: CORSAIR Hydro Series H60 http://goo.gl/pGk7a0

Your PSU isn't that great. Its not in tiers 1, 2a or 2b of http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html.
Even if it isn't causing a problem, I'd be looking for a replacement. What 12V, 5v and 3.3 readings are you getting from bios?

The restarting business is because 'auto restart on failure' is enabled. You can disable it by starting in safe mode - http://windows.microsoft.com/en-au/windows/advanced-startup-options-including-safe-mode#1TC=windows-7

But instead you should try to work out why its restarting. The most likely cause is the CPU getting too hot and shutting down. You can also check CPU temps in bios. What readings are you getting?

Sounds like a CPU temp problem though like i7baby said - you could probably do a better PSU. Are you overclocking at all? Check your temps, try reseating your cooler - make sure your fans are operating correctly and you don't have a family of dust bunnies or wires obstructing your airflow.

If it's not a temperature problem then I'd look more towards the PSU not being able to handle the load as your GPU fires up. You should have more than enough juice but different quality PSUs will handle power draw and spikes differently.

Thanks for getting back to me so fast, and sorry I didn't respond faster, I had a early class.
Here are the reading from BIOS
Host Clock 99.79 Mhz
+3.3v = 3.403v

+5v = 5.130v

+12v = 12.312

System Temp 32 c
CPU temp 34 c

Also here is a screen shot of the the temps and sensors for the cpu and gpu after about 2 minutes of gameplay.

Your voltage readings are OK. A bit high maybe. But OK.

And your CPU temp is OK. If you've installed Easytune - the utility software that came on disk with your motherboard - you should be able to get the CPU temp while gaming. Post the result.

Hey guys, so I opened up my case to make sure the fans were clear and to reseat my GPU (I know this should have been one of the first things I did) and there was a case screw stuck in between the GPU and Motherboard, I don't know if this would cause the problem or not but I removed the screw and took out the GPU and put it back in. I booted up the PC and played Fallout for 30 min straight and had no problem. Usually it would crash withing 8 min. I need to get back to studying but I will try to put more time into playing for a longer duration of time to see if the problem is fixed. If the problem is not fixed or if it returns I will come back to this thread. Thanks for taking time to respond and I hope I didn't waste it by not opening up my PC sooner. Thanks again and hopefully this is not just a temporary fix. :)
