I have a 2 year old Dell desktop Dimension E521 with Windows XP. Recently it has been freezing several times a day, sometimes while on the internet (with both Firefox and Internet Explorer), sometimes when just working on a Word doc, sometimes with nothing open and the screen saver is on. When I hit Ctrl+Alt+Del the task manager doesn't even come up and I have to press the power button on the tower to get it to shut off. Ran several virus scans (AVG, avast!) and they say no virus, but a friend who is good with computers said it sounds like a virus. Cannot do a system restore, it goes through the process and then says "unable to restore to specified date". I have tried at least 10 dates and none work. A few times after it freezes there is a loud beep coming from the tower, I read in a previous forum that could be a fan problem, but I am also having other issues besides the beeping. Any ideas what I should do?? Thanks MP

I would first take steps to satisfy myself that the system is not overheating.

Freezing is one of the symptoms of overheating, among other things.

I would check to ensure that the fans installed are all working properly (visual observation) and then I would enter the BIOS and check the registered CPU temperature after one of these freezes.
