Miraculously, but after about eight attempts, the screen was good again. Whatever...
I had changed my color settings from 256 to 16 bit but not restarted right away. When I noticed some weird color patterns (vertical stripes in some backgrounds) I decided to restart.
When the PC came on again, all I could see was a snowstorm of color pixles flickering on my screen. I tried to press F8 to start in safe mode but did not succeed.
How can I get it back to working?
It is a laptop PC with Windows 98 SE.
Thanks so much and I'm sending this from a friend's PC
