My Pentium 133MHZ system previously had 24 MB RAM and it was working fine. I purchased another 64 MB of RAM and included them into the system. After installing them and restarting the system, just before the Windows desktop appears, a BLUE screen error message appear saying :
DriveSpace VxD and DriveSpace real mode driver mismatched. You may need to reinstall them. Press any key to continue.
When I press a key, the Windows desktop then appears. But now my system became horribly unstable and the "illegal operations" error message appears very frequently. I tried removing the 64MB and use only my old 24MB but the blue screen problem still persisted. I also tried using just the new RAM and the problem got even worse, the whole system seems to reject the RAM, error messages such as "internal error", "fatal error" start to appear. What do you think I should do? Do you think reformating the entire system will help?
