I'm having issues with my PC randomly crashing while gaming. Everything will be fine then suddenly the PC freezes up and that's it. Need to hard reset. Screen doesn't tare to indicate video card. CPU passed the Intel diagnostic tool however did hit 100 degrees. RAM also passed the tests. What else can I try? I have noticed the CPU voltage seems to jump all over the place while I'm gaming. Not sure if this is normal. Running an i5 8600. Did have a power surge a few months back that destroyed my power supply. Wondering if the CPU is damaged as well.
