All of a sudden the computer won't boot & won't go into safe mode. I get fatal exception error 0147:00001970. I've also gotten a number of other wacky errors one saying that their was a sudden "stack fault" and another that says himen.sys not found. When I try to boot from the floppy & reinstall windows the cd it stops at a certain point and says"restart the computer" wherein it all starts over again. What could possibly have caused the cumputer to corrupt itself like that?
