Problem: This happened when one night i was playing dota2 then my PC suddenly shutsdown and turned on automatically by itself this time monitor goes black no display, Now after what happened monitor no display as in black, even when my cpu turned on, but when cpu is turned on i cant shutdown it manually using the power switch i have to unplug the cable or turn off the Voltage regulator. I trouble shooted all posible problems i replaced the mobo w/ a newer one but still the same result and same problem, and also I tried to reset the cmos but still the same, switched ram slots, boot w/o HDD and CDROM but still the same.
I hope you can HELP me w/ this problem. cuz my PC is so important and useful to me.
