I'll try to shorten this some... I was having some problems that I determined were either caused by the hard drive, corrupted WinXP (Media Version), or my RAM. I ran MEM Test and it failed so I replaced the RAM with one 2G stick. That solved several issues. I still had an issue with switching users. I had the computer set up for 4 users with myself as the admin. My partition(is that what it's called)works just fine, but if I log into one of the other three it will not allow shutdown, restart, log off, or change user. It forces me to do a hard shutdown. I decided that my OS may be corrupted so I took the opportunity to install a bigger faster HD and installed WinXP Pro. The problem did not go away. This doesn't make sense to me. What else could cause this? I also have a new problem. Sometimes the copy and paste feature will just quit working. It seems to copy but then the Paste will not "light up" when I right click in the program I want to use. Could this be driver related?
