a computer i just got doesn't display anything on the screen when i boot it up. its a Compaq presario sr1103wm when I turn it on the green light on the tower turns on and I can hear it, but the moniter shows nothing. so I took out the hard drive and but it in another computer, at first it just showed the windows logo then stopped..so then i restarted it and reformatted it..after that it worked in that computer..but still wouldn't show anything on the screen on the other...it doesn't beep or anything so i don't think its the ram...and it has a built in video card...the last owner told me it was a virus or something...any suggestions?
