I have an old gateway desktop that was given to me. I use it as a TV where I work. About a week ago it stopped loading. I would see the gateway logo and then the windows screen would come up and had LOTS of streaks that looked like rain through it. then it would go to a green screen and not do anything. I couldn't even go in in safe mode. So I re-installed windows 98 from the rescue disk. It still wouldn't load, but I got in through the safe mode and took out some of the files that were locking up the virus disk like video games and ACCOUNTING software. I finally got it to work without safe mode, but it asks EVERYTIME I turn it on which mode to start in. When I tried to change the screen resolution and color settings, it always goes back to the 16-bit 640 X 480.

Any ideas? Thanks.can you try enable VGA mode? DLoad install and run Everest HOME...this will inventory all your components and PROVIDE links for drivers...
Sounds like the video driver needs re-installed.
Any problems Post back.
