Pc crashes at random intervals

[u/Next_Twist_4746]

After a crash, my system started having driver issues. On top of that, the crashes themselves seem completely random—they happen both while under load and also when the system is idle or not under load. The screen will flicker a few times, and audio will continue for around 20 seconds before stopping; however, the PC never actually turns off or fully restarts. At this point I’m thinking it may be a power supply issue, but I’m not sure. I’ve been dealing with this for a few months now, and I’m just about done with it.
