My PC, running Windows XP, has suddenly decided not to function correctly after three trouble free years.
The problem came to light when Sage Accounting software suddenly demanded a password even though I have never set a password.
I uninstalled and then reinstalled the software but the problem remained.
I believe the problem is to do with security and the relevant files are in the registry and are not deleted with the uninstall.
I have no idea how to resolve this issue apart from trying a system restore to a point previous to the problem occurring.
Unfortunately, when I ran system restore I got the message that it was not possible to restore to the selected point.
I have no idea whether these two problems are connected.
Is there anything I can try or do I need to do a complete Windows reinstall?
