Vicki-
What exactly happens- is it that you can't boot up Access anymore? Do you get an error message?
Have you run an antivirus and a registry scanner? If not, I suggest these 3-
1)
http://www.pandasecurity.com/activescan/index/ (one of several online scanners- does a very thorough job)
2) ACS (a jack of all trades program for antimalware, disk defrag, and registry optimization- FREE)

Malwarebytes and
Spybot S&D. AVG and Adaware are Ok, but the quality has decreased over the years.
Just the other day I had a malfunctioning program and the cause was that the computer had 2 HD- one for mirror backups. At one point suddenly the C: root drive became the backup drive with some root funtioning left pointing to the correct, now E: drive. It was a mess, and there is a trick to switch the root lettering back but it is a pain in the you-know-where. In that case I simply did a Windows XP repair install.
