I recently uninstalled a problematic anti-virus program on a pc, ran
adaware, spybot s&d, ccleaner etc and did a defrag. Since then I've been
unable to get open a full screen dos prompt, I just get a blank screen. None
of my dos applications run in full screen either, It's as if the program is
there (as if I type "exit" at the dos prompt the window closes) but I can't
see anything. I can run in windowed mode without any problems.
Can anyone suggest what might have caused this? Can it be rectified fairly
easily without losing any existing data?
I really appreciate any help, thanks.
