Computer freezing after it goes to sleep?

[Cata|yst]

Whenever i start my computer after it has gone to sleep or entered screen saver mode, my computer would just freeze. the only fix is that is that i would have to power off it =[.

One time, when i tried to open up Task manager, i got a message saying something like "failed to start up security bla bla" I wasnt able to paste the s/s, as i had to power shut it.

What could be causing this?

Are you running vista?

If so, try updating if you haven't with hotfixes that could solve your problem. This one should work: http://support.microsoft.com/kb/943899

The task manager might be a different problem. Try this thread to info: http://www.vistaforums.com/Forum/Topic13079-9-1.aspx

maybe the problem with your windows.

reinstall it, maybe it will fix the problem. but if you didnt want to reinstall, just disable the screensaver

thats jsut waht the first guy said.
