Thank you both for your help, I did just as you suggested and updated and ran both programs. Part of my problem is fixed. I can run my computer now without it locking up on it's own but it still locks up anytime the explore funtion is needed. Could have I accidentallly deleted a needed file? I can't run certain programs nor can I use the explore my computer or control panel without it locking up. Additionally, when I reboot I get this message "C:\Windows\sp.dll: Error opening the file. There may be a disk or file system error."
Thank you again for your help and I would appreciate any additional help with this problem.
