Hello, My PC is rebooting randomly. I have the impression that it happens more often during gaming but I'm not 100% certain. What complicates this matter is that in 2017, I replaced both my PSU and Mainboard since the machine wouldn't turn on anymore (I could not decide whether the PSU or Mainboard were at fault, so I replaced both). The system is this: Win10 64bit CPU: Core i7 4790k (from 2014) RAM: 16GB Ram by G.Skillz (from 2014) GPU: MSI GTX970 (from 2014) Motherboard: MSI H97M G43 (from 2017) PSU: Corsair RM 650X, 650W (from 2017) One possibility that I tried was to see whether maybe the temperatures were too hot due to this year's intense heat. When playing games, temperature on the GPU rose into the upper 60s, which seemed fine. I have also updated the mainboard drivers and will flash the BIOS to the latest version next. But what other tests can I run to narrow down the source of the problem?

You could run memtest overnight at some point to verify RAM health: http://memtest.org/ Run CDI to check HD health: https://osdn.net/projects/crystaldiskinfo/downloads/69917/CrystalDiskInfo7_7_0.exe/

So, memtest ran 4.5 passes without error. I guess the RAM is exonerated? I'll have furmark run next.

I have news! I can report that my computer rebooted during a Furmark stress test. The GPU was loaded at about 98% and within 15 or 20 minutes, the temparatures rose to 77 degrees. I didn't catch the actual data when the reboot happened, but from across the room it didn't look much higher. Can I use this to narrow down the source of the crash futher? I suppose that a faulty PSU and a faulty GPU could both fail under high load. I'm inclined to think it's the GPU that fails, since the 650W power supply should easily stem the ~145W TDP of a GTX970.

If you're on the latest motherboard BIOS then I'd try using onboard GPU temporarily and see if the reboots stop or continue. If the reboots stop then it's highly likely that it's a GPU problem or a failing/underpowered PSU issue.
