just a "thought":
did you take the panel off and cleaned up the "dustbunnies" with canned air ??
My pc has begun to suffer screen freeze.I can be in here,on home page or just anywhere and out of the blue I get locked up.Cursor still moves but no response to anything I click on.Putting cursor on the stop button usually makes it light up but now it is grayed out when the freeze happens.The only thing I can do at that point is hold in the on button and force shut down.I have run spybot,adaware,stinger,schredder and housecall and panda.Am I taking the wrong track here? It's like Ive been disconnected but all modem lights indicate connection.Any thoughts? I also have checked startup menu.I have posted in computer help also but thought maybe it might be a bug so Im posting here.
My specs are listed in profile.
