ook so my desktop has been having problems for awhile now. the screen has been going from normal to black to the no signal screen to back to normal., but the blue light on the monitor still stayed on it started when i was playing wow but eventually started happening when i used internet explorer and even booting up the machine. i took it in. they said they could'nt find the problem. i got it home and it worked fine for a week . then it started back up again. i tried cleaning it, checking the gpu temp, replacing the dvi cable, triple checking conections . problem is still there after all that. so i take it back in to get it repaired t, this time they say it's a virus and are going to charge 200 bucks to remove it. i dont have the cash for that, so i took it home and ran a few different free virus checking progams and its still going on. any and all help would be much appreciated.
