Indeed, the amount of things starting at the same time (even more when there are more than one resource hog app) can cause similar problems, just 'cause the processor doesn't have the time to attend all request in that moment.

Also, can be a problem with security center (assuming that you've XP + SP2) which for some reason don't check Norton as "antivirus protection installed" if that's the case you'll have to live with it, just configure security center to Not Supervise antivirus protection.


Think on anything you did before the problem start, even changes that you'll say are trivial...that could give u' leads to find the 'cause faster
