So I have a AMD fx 6100 cpu with stock cooler. I OC it to 4 ghz. SOO I was running prime95 test on my cpu and burn test on gpu (GTX 1060 OC to 2 ghz)... Cpu was hitting 65 C Motherboard components were 60-80 C. It was all fine until I heared pretty loud zapiing noise for 1 sec and PC turned off. I also gave off teribble smell. PC recovered and now Im here asking what went wrong. PSU is Whiteenergy 500W
