Boot to the DOS prompt and rename the autoexec.bat and config.sys files; e.g.,
C:\>ren autoexec.bat autoexec.dux
If that fixes the problem, ren the config.dux file back to config.sys. If the problem is still gone edit the autoexec.bat file…
…and start remarking-out lines one at a time by putting rem followed by a space in front of each line until you find the line that is causing the problem.
Otherwise, rem-out lines in the config.sys file.
How do I go about unistallin the drivers and reinstalling it again.
Try removeing one of them with the Remove button in the Device Manager and reboot. You may loose your display when you remove the driver. Just turn it off. Or, “feel” your way to the Task Manger with Ctrl-Alt-Delete and shutdown blind like I do. Larry
