Once booted, however, he is getting a variety of program failures. Office programs all report that the program hadn't been installed for the current user. Antivirus will run a scan of the computer, but won't launch the interface due to errors. The computer runs at a good speed for about 10 minutes, and then starts to slow down to a crawl.
Could all of these be tied to the CMOS battery? They all started happening at about the same time...
Thanks!
