I have a celeron 333 w/built in video and I just replaced the power unit for a friend. I am using my monitor and when I boot I show the win 98 screen clearly but when it finishes booting I get a bunch of horizontal lines like it has the wrong video driver. Since I can't see the program to reset the driver, how do I resolve this. I thought by going into the bios I could change something but I dont see anything in there that might help. Do I have to get his monitor or is there something else wrong that I am not thinking of right now?
