My comp started acting weird today with the monitor flashing on and off then staying off...i rebooted it came up fine and then it happened again...i took the vid card out and air dusted it out and put it back in and nothing. i switched vga to dvi and nothing. turned it on again and it booted up with bad res and artifacts all over the screen then the comp seemed to freeze and the monitor went black again. I just tried turning it on again and all seems well altho its only been on for 2 min. Is there anyway for this to be anything other than a hardware problem? I got a p4 3.2ghz extreme edition with HT and a geforce 6800gt card with 3rd party cooling. I've had this setup for a long time now..asus mobo as well replaced about 6 months ago.
