PC rebooting after playing for a while. No BSOD

Hello guys,

I have a problem with my pc, it keeps restarting (it directly shutdowns, there's no "previous glitch" or "black screen for a few secs") after playing 30m-2h of L4D2 or playing 2-3hours of Warframe (if a restart the game each 1-2h it avoids the reboot which seems to point to a memory leak problem, but a memtest i did seems to disagree on that)

In only happened once but it's worth mentioning that after having a reboot while playing L4D2 and hastily getting back into the game it rebooted again in less than 30 seconds.

Specs:

Intel Core i7 2600 3.4Ghz /w Noctua NH-D14
Asus Sabertooth P67 B3
ASUS GeForce GTX 970 OC STRIX
Ripjaws DDR3 1600 (2x4GB)
Corsair HX850 850W
* There's no OC involved

As far as my tests go:

- There's no BSOD, even if i disable the automatic restart.
- I've done a 14h MemTest and found no error.
- I've logged the temperatures just before a reboot with SpeedFan and got:

Seconds GPU HD0 HD1 Core 0 Core 1 Core 2 Core 3
59683 63,0 27,0 30,0 51,0 56,0 54,0 49,0

Which correct me if i'm wrong but seems acceptable temperatures (the max temps i've recorded is 69 on my GPU and 61 on one of the cores)

- I've done a 15min FurMark and 3 runs on the heaven benchmark and got no crash.

In short, i suspect that the problem may be on either the PSU, the Motherboard, the CPU or the GPU (not because of temp reasons), Any idea on what could be or which more tests could i do?

Looks fine to me and that pretty much rules out the CPU.

I think i can rule out the GPU: i've done a 3 hour L4D2 session on another pc (changing it's GPU with mine) without any kind of problem.

I've checked the BIOS and all i've been able to find in regards of voltage is:
- CPU: 1.192V - 1.200V (dancing between the 2)
- 3.3V: 3.344V
- 5V: 5.080V
- 12V: 12.096V
 


Okay, it's good that you have ruled something out, it helps narrow it down. Those voltages look fine, although as far as I'm aware there's no easy way to monitor them when it's under load.

I did some benchmark runs but just to make sure i've done a 1h SMALL FFTs test on Prime95 without any kind of incident, max values were:

1.356 V
61ºC Core0
70ºC Core1
72ºC Core2
67ºC Core3
72ºC Package
107.82 W Package Power
102.89 W IA Cores
6.66 W Uncore
(All CPU's on 100% utilization)
 

Looks fine to me and that pretty much rules out the CPU.
