I found the following reply from Orange Blossom to be helpful for checking my system integrity, so am passing the solution to you.
Have your Windows XP installation disk on hand in case you get prompted for it.
Click on Start -> Run. Type in sfc /scannow. Make sure there is a space between the 'c' and the /. Your computer will now check system files for problems and will attempt repair of any damaged ones. If it cannot repair them, it will replace them which is when it may ask for your Windows XP installation disk.
If this doesn't work, my next thought would be a repair install which would keep your data safe. However, I don't know how to do this, so someone else will have to give you the directions for that.
By the way, when you did the Window's One-Care on-line safety scan, did it find registry entries that needed to be fixed or deleted? If so, did you have it do a back-up (I believe this is automatic) and have them fixed?
