Alright, I have
AMD Athlon X2 4000+
ATI X1800
nForce4 Chipset
every once in a while my screen gets unresponsive, except for my mouse. but i can still hear sound, and it seems to still be running according to programs that were running that can show how long they were running for. But the keyboard does not seem to do anything the screen does not respond only the mouse still moves on it. I have been told that it could be that my 3 year old ATI X1800 is finally dieing if it is, how can i be sure.
