I am using a Gateway Pent 4, 256mb, win98 machine. I booted up one day and the monitor remained black except for the flashing red-blue warning to make sure all cables are properly connected. I've switched the video card into another similar machine, and it works, so I know that's it's not the video card. I even swaaped the hard drive from the same similar machine to see if it had to do with the operating sysytem, but no avail. Anyone know of any new avenues to approach? Many thanks!
