The machine started of with many HDD errors, fixed them then Win 95 says must be reinstalled. Tried reinstalling but it would lock up at various points. I have changed memory, and cd-rom but nothing helps. Now all I get is an error that states: "standard mode: bad fault in ms-dos extender" what could it be? p.s. I have tried a new boot disk and mscdex.exe file. This is win 95 ver A and it is on a compaq presario and it happens right after you start the setup and get throught the first 100% screen before anything actually happens.
