sounds like the power supply or motherboard esd is tripping from a surge.. probably the mb kids will drop kool aid and whatever all over the board then tell you they didn't do it nowdays.. look over the board carefully and you'll probably find the culprit
check capacitors of your motherboard and other computer parts. Had same problem before and capacitors are the problems.
