Windows 10: PC restarting randomly

Hi everyone.

I built my desktop in August 2020 and have experienced random restarts a few times. I was video conferencing on Zoom when this happened today. If I remember correctly, the first couple of times it happened last year, I was also on Zoom then.


I can't see a reason for this. It does not overheat, nothing else is apparent before the crash, it just happens without warning.


I've done some research and I believe this is associated with system data corruption or memory/driver incompatibility issues. I have tested memory with RAMCACHE III it's 100% good. I have always regularly completed updates. I also turned off the fast restart feature but it still happens.


Has anyone had a similar experience? I'm looking for advice about why this is happening and what to do.

Let me know if I have missed any info.


Thanks in advance.

PC Randomly Restarting after installing new Ram!

Tried your suggestions, but still had a restart! Also ran memtest overnight (13 hours according to memtest) and had no errors! Also ran Passmark Burn in test for a couple hours testing everything and had no errors or restart. Could fitting the new ram have triggered something to go bad like my mobo or psu?

Pc restarts randomly

I've got a problem with my pc, it restarts randomly without any bsod, I get event 41 only. Can it be caused by bus speed spikes? Here are some I saw:
 





As you can see the cpu multiplier is set to 40. The bus looks like raising close to 103MHz, it doesn't seem ok.

Here's the setup:
PSU: Corsair VS 450W
MOBO: MSI H81M-P33
CPU: Pentium G3258 @4ghz 1.2V
RAM: Crucial 8GB 1600MHz CL11
GPU: Gigabyte GTX950
HDD: Samsung SP2504C
ODD: Asus DRW-24F1ST
Windows 10 64-bit

It's crazy because I can run world of tanks and it will restart over and over, then I would run gta 5 and it will be fine.
