Self taught intermediate user here, no expert! Trying to clean up an old Windows 98, Compaq PC, Pentium III (to get rid of it), and it has worked great! I cleaned up everything I could think of, ran CCleaner, and then trying to get back on the 'net with Firefox or IE, could not connect. The machine tells me the Intel Processor Serial Number is disabled. I open the settings, click enable, restart, and it goes back to showing disabled. I'm going in circles over and over. (I don't know what happened while I was cleaning it up.) Any ideas pleeeeeez!
