I did a "system devices property dump" and according to it my CPU is a CyrixInstead m2(MMX). The computer was bought from CyberMax and they went out of business last year. So no company support is available because I tried that first. I did try what you suggested, booted up in "safe mode" and attempted to remove the hard drive controllers. It would let me remove the "dual" but that did not take away the others. On reboot the "dual" is again re-installed. They others can't be removed without first removing the dual. What do I do now?
