I was openning a program on my PC last night, when my computer froze!   I didn't think much of it, so I just hit 'restart.'     My computer takes forever to start up, a problem that remains a mystery, so instead of waiting I instead went to bed.  When I woke up this morning, I tried to log into my pc, and again it froze!  Again, I restarted.   This time...  the computer didn't get far at all before it brought up DOS, and told me that I was missing this file:     VMM32.VXD   .. and that windows couldn't be started without it!  The screen also promted to me that if this file wasn't in my PATH then I might have to reinstall Windows98SE  (wich I no longer have any disks for).            WHAT IN THE NAME OF JESUS DO I DO?!?!?!
