I have a Compaq Presario, 9000 series, 128 Megs of Ram, 6 gig hard drive, win 98 SE and 56K Modem. One day it was working fine, next day, no video at startup. I'm stuck. The tower still powers up but no post, no video at start up. I tried replacing the video card, no luck, replaced the memory but still no luck. Tooled around the Compaq site, well you know the rest. I need a confirmation, is the motherboard on the blink or what?
