I have an HP 8655c pc w/ a pentium 3 600, 192 mb ram, and am using the win 98 OS. Many times while i'm using my computer, the screen will suddenly go into this widescreen format, and the window will scroll constantly from top to bottom so that i can't see whats displayed on the screen and am forced to reset the computer. My video card came with the system so has no name brand. It's soldered to the motherboard and all I know about it is that it uses 11mb of shared memory. I'm thinking if anything its the video card. Any advice on what to do?
