My system is restarting randomly when gaming. There is no BSOD and no crash dump created even though I've got it set up to do so.
CPU - AMD 8350
GPU - R9 290
Memory - 8 Gigs Gskill
PSU - SeaSonic Platinum Series 1200w
MOBO - Biostar TA990FXE
My knee jerk reaction was that it must be my graphics card because it only crashes during gameplay, but because the crashes create no dumps and they cause reboots half the time I think it might be a faulty PSU (Which would make me very sad because I bought this PSU because it was in the Tier 1).
Additionally, I've tried underclocking my GPU to solve the issue and that has gotten me nowhere. It seems the time to crash/reboot is independant of graphical settings. I've tested it with DE:MD on ultra settings and medium, and the crash time has been fairly random and independent of the settings. Additionally, a clean install of Windows 10 did not solve it either.
When it crashes and doesn't simply cut to black and reboot, it crashes with a frozen screen and a looping sound.
Temps are very unlikely to be a problem. I've monitored them with MSI and RealTemp.
Does anyone have ANY other ideas on how I can actually diagnose this issue without simply purchasing new components before I can really know whats wrong?
I've tried running HWMonitor in combination with Prime95, and my system does not crash during it. HOWEVER. Once I let the test run for a while and then stop it, my computer then crashes. I've confirmed this by repeating it 3 times. Additionally, HWMonitor shows my +-12V rails as only putting out 4.9V and -4.8V respectively. I know HWMonitor has its issues but it does give some credit to the bad PSU theory I have.
Installed Furmark and ran it. GPU temps got high until I realized that I didn't have the fan cranked up the whole way. Once I did so the temps fell to reasonable levels. However towards the end of the graph the performance of the card became very unstable, from around 100fps average to 50 or 60. Upon stopping the test the system did not crash or reboot. I ran Prime95 again and ran it for about 15 minutes and then stopped the test. This once again caused the computer to reboot.
