Hi, I've been getting some odd reboots on my PC as of recently.
A month ago, I was getting some that seemed fairly random, sometimes upon changing maps in TF2 or booting up the game but outside of that I couldn't see a pattern. I did some dust cleaning, switched power from one PSU PCIe slot to the other (might have been placebo) and it seemed to disappear.
However, just a few days ago, I started getting more frequent crashes, although on completely different tasks: a very common one is upon Preview rendering in Premiere Pro, I just get a PC reboot in the middle of it and I have no clue why. CPU temps seem fine (always below 75°C, and I'm using a Ryzen 7 5800X lol), and I was keeping an eye on VCore as a test and I couldn't see it go past 1.4 while it happened, so I'm genuinely confused. The event I'm getting is the Kernel-Power Event 41 (63) in Windows 10. My version of Windows 10 is not up to date if that ever matters, it's from a year ago, my Windows Update seemingly broke (it can install minor fixes but not major updates). I believe I have PBO on, with a slight voltage negative offset, but I did all this a year and a half ago so I'm not 100% sure how I tweaked it exactly. Nevertheless the reboots only started around a month ago so I doubt that would be the problem. My BIOS version is that of a year and a half ago when I built the PC.
Full specs:
MSI B450 Tomahawk Max II
Ryzen 7 5800X
2 500 GB SSDs (1 M.2 NVMe, 1 SATA), 1 1 TB HDD
32 GB DDR4 G. Skill Ripjaws V 3200 MHz (4x8, 2 from previous PC, 2 bought upon upgrading)
GTX 1070 (EVGA XC version)
Be Quiet! Pure Power 11 CM 500W (80+ Gold, bought a year ago bruh)
Fractal Design Focus G
Thanks in advance, it's really annoying and I'm afraid it will fuck up my drives and peripherals at some point.
Side note: none of these reboots involve a BSOD, only a black usual reboot screen.
