I upgraded a PC to Win98SE for a friend of mine a couple of months ago. This is a pentium 233 mmx, 64 megs, onboard Sis video chip.Everything was happy, it went well. Recently his display went to some diagonal lines. Looked like the images were diagonal too. k...so I boot to safe mode, delete video driver and monitor. Reboot to command prompt, run regscan, reboot, let windows autodetect and install video driver(from the cd that came with the motherboard) and monitor. No help. Next I reboot to safe mode. I move that graphics accellerator silder all the way down. This time I can reboot in normal windows but can only display 16 colors. I move the accellerator to the next notch and reboot. Now I get back all my color options. I move the accellerator up to the next notch and boom.. the display goes screwy agian. When I get the
accellerator back to the second notch(from the left) and won't let you move it to the right anymore. I'm sure that before the display problems the slider was all the way to the right. It works like this for now but I suspect there is still something wrong. Oh, I don't remember exactly when in this process I did this but I ran the system file checker, it found a corrupt file and asked for the 98 cd to replace it. I don't remember the name of the file but it was replaced. There are no games on this PC. The only SW loaded recently was Juno Internet SW. No new HW. That I know of. Will the slider being on the second notch affect performance? What could have caused these changes? What gives?
