After using the computer for a certain amount of time, depending on applications running, the frame would eventually freeze, sound would begin to loop, and then the screen goes gray (sometimes with a brown hue to it, can't tell, definitely not black/off).
This happens a Lot faster when using 3D applications/games (within 5 minutes or so).
I've tried all of my games so far and it happens on every one of them at various intervals.
I suspect the problem could lie in faulty Page File or VRAM, which would fill up faster when using 3D applications.
Though i have no idea what could be causing said problem.
This is a fairly serious problem, as I can hardly get anything done that has a 3D interface, including games, modelling etc.
