Everything I try to run pops up a black DOS window first points to ntvdm.exe, then quickly changes to desot.exe, displays a message in the window "Program too big to fit in memory", then quickly closes. The program never launches, not directly or from a desktop shortcut.
I can log into Administrator in Safe Mode (and Standard Mode), I can run Task Manager, but not My Computer > Properties. IE nor Firefox will run.
It was working a few days ago (except for viruses). My sister-in-law gave it to me to fix. After running AVG, it found about 8 infections, however couldn't be removed because I did not know the Administrator password. I tried [blank/none] (along with several others) however it popped up a box that said it couldn't proceed.. something about trying to use a blank password... I now know that the Admin password is [nothing] because I just logged in today in Safe Mode. It doesn't do me much good though, because I can't run AVG anymore.
Please help! All I know is that it's running Windows XP (not sure which SP, probably 2).
