Folks: I am having a bunch of Illegal Operation messages with DLL file endings and can only point at a bad motherboard as I have restored the OS several times and they continue to happen intermittently. A few are MFC42.DLL, MFC40.DLL, KERNEL32.DLL, PR32301.DLL, COMCTL32.DLL with computer continuing to crash over and over again. There are also Netscape.exe Illegal operation messages and blue screens VXD fatal exceptions. When I put a new hard drive on this system the same things happen so I must rule out a hard drive failure at least at this point. Scandisk reports no errors and the systems diagnostics reports are all positive. Any leads would be helpful. Michael Curious about the people moderating your messages?
