My computer has been working fine until today. I was on the internet for about an hour when the computer shut off, which has never happened before. I thought the power went out, but it hadnt. The tower is plugged into a powerstrip. Computer turned back on by itself, then off, then on, then off. This pattern would repeat until I unplugged it. Sometimes computer will remain on for up to two min and sometimes it turns off immediately. Cant launch system restore, because comp wont stay on long enough. Have restore discs, but cant use, again, because computer turns off before completing.
Can sometimes get to safe mode screen, BIOS, but totally unsure of what to to to fix this.
I have AVG virus protection and Vista operating. I have never had a problem with this computer.
Computer is 16 months old Gateway FX 6000.
I opened the case and dusted the fans. What else should I do?
