Well, I hate to say this, but you may have a virus.  The exact same 
thing happened to me when I caught the  Stoned virus.  Get yourself a
good virus checker and scan your system.  The first thing that went
crazy on me when I caught the virus was the memory manager.  Stoned
(and other stealth type viruses) steal some memory to "hide" in and 
this totally messes up emm386.

Yep, this is a classic symptom of the Stoned virus.  That 2K 
difference may be the memory that Stoned stole to hide itself
in.

This is another possibility, my brother had the CMOS on his computer 
scrambled (from his 15 month old daughter flipping the power switch 
on and off is my guess) and things went totally crazy.  However, your
symptons don't sound like a BIOS problem, they sound an awful lot 
like a virus.  Like I said before, get a virus checker and run it,
it certainly couldn't hurt.  Make sure to check all your floppies
too, Stoned is transmitted in the boot sector of floppy disks.
