Had a power outage last night, while on computer playing games, for one hour. When power came back up computer would kick on for like 2 seconds then kick off, and would cont. cycle of turning off and on until i unplug it or turn off power supply. Its a 400w power supply not even 6 months old, that i got with new graphic card. Computer was plug into surge protector so i don't know whats the deal. Please help me.
