Occaisionally, windows 98 will freeze and faint vertical lines, about 1 cm apart, appear all across the screen. I do a hard boot, and during the boot, I see similar lines appear on all my boot screens, although these are more pronounced and are about half an inch apart. After the Windows 98 splash screen goes away, the system freezes again. I can boot in safe mode, but the lines are still apparent. I have found that the system freezes when running "display.drv=pnpdrvr.drv" in the boot section of the System.ini file. I have a 3dfx video card, I've tried uninstalling it and the display driver, and reinstalling them. I've tried turning down my hardware acceleration incrementally until it is down all the way, and the system still freezes when running that part of System.ini and the lines are still there. The weirdest part of this, is that it tends to go away on its own, for no reason I can find. Maybe a week later, it pops up again. Right now, the problem seems to be lasting longer than usual, which may be because this was the time I uninstalled and reinstalled the driver software.
P.S. whatever fix you guys/gals come up with, would it be possible to fix this without reinstalling windows? I lost my OEM cd a while back.
Thanks in advance.
