PC restarting, and I dont know why.

[Berti93]

So, when I play a game(ac unity or ryse son of rome), my pc suddenly crash and restarts randomly.
And it is not overheating. I monitored all the temperatures, and my gpu never goes beyond 70 C and my cpu is cool too.
Maybe it could be hdd faliure?
My spec:
AMD FX-8120
Gigabyte GTX 970 gaming g1 windforce
8 GB DD3 AMD entertainment edition RAM
SAMSUNG HD502HJ HDD
Gigabyta GA-970A-UD3 motherboard

may help monitor the error message when pc attempt to crash.

It would more likely freeze not re-boot if it were a hard drive issue. Check the event viewer in admin tools.Windows logs and then system. If it is a hard disk problem, you will see the errors there. Do you mean blue-screen and re-boot? If so go to system in control panel, advanced system settings, startup and recovery. Un-check re-start machine in case of system failure. If it is in fact blue screening, the screen will stay giving us something to go on to help. Power supply? Your rig need a lot of good quality juice.

Thank you I will test it right now.
I have an XFX 550 pro. Not much but it should be enough. The rebooting is full random. It can happen in 10 minutes or after 4 hours of straight gaming.

No blue-screen at all. Just black.

The event-log only show one critical evet. Kernel-Power 41(63).

That just means it shutdown unexpectedly as we already know. PSU could be maxing out with that 970 and fx chip.

But that was the case with my older card, which was an hd 7950.

So I have run around a few tests. Disabling the optical drive and some fans. Then I run the game again, and I realized that my pc only restarting always on the same mission on the exactly the same point everytime. So could a game crash cause this?

may help monitor gpu and cpu work load then you can read logs. when pc crash.

Update: I bought a new psu(xfx ts 650w). Still doing it... I will run a memtest tomorrow to see if my RAM is okay, but I highly suspect my old samsung hdd.
