Having a really bizarre issue with random reboots. Basically my PC is rebooting semi-randomly, but the behavior is completely the opposite of what would typically be expected: when playing games which stress the system under heavy load it never reboots, but when the system is completely idle it reboots frequently.
The issue is definitely not software, driver, or OS related, since the reboots occur even when it has not been booted into Windows.
It also comes and goes in waves: sometimes it happens every few minutes, then sometimes it will go days without happening.
I replaced the PSU and that seemed to offer some improvement at first, but it did not resolve the issue.
Also I've performed plenty of stress testing using Memtest, Windows Memory Diagnostics, Furmark, BOINC, heavy gaming, etc. and none have resulted in any issues (and as noted, it actually seems far LESS likely to happen when the system is under heavy load).
Has anyone ever experienced this kind of issue before? I'm thinking it's somehow motherboard related but it would be nice to get some kind of confirmation before buying a new one and replacing it. I'm also curious how it's even theoretically possible that a system would be MORE stable under full load than when completely idle.
