Windows 10: PC randomly restarts

My PC randomly restarts. I checked for HW issues none found. Used the instructions here and enabled Driver Verifier. The PC restarted again but no dump file, no BSOD as usual. How to know which driver is doing this?

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.
