So like every 10 or 20min my screen will shake a little and white lines will come up then everything just freezes besides the mouse. Anyone know what could be causing this?

The first half sounded like it was a problem with your monitor cable, but you're saying all of the programs freeze as well, and you can only move your mouse (but not actually doing anything with it)? No idea. Can you hear any unusual sounds, like grinding or your computer fan sounding like a jet engine?

ya after the second time i checked the cables to make sure they were plugged in and it hasnt happend again yet. but ya when it happens alls i can do is move the mouse... nothing else

ok its still doing it any know why?

Monitor could be on its way out.
Did you buy it recently? and if so, is there a warranty?

oh ya i never thought of that. Its a pretty old monitor so thats prolly why

Well i open it up and my graphics card gets extremly hot. Could this be why?

Zzz

If you have another monitor you could borrow, try hooking it up and see if it still does it.

If it doesn't, then throw your old monitor out and get a new one. If you can't afford a new one, look for a cheap one on craigslist.

yes absolutely, download a temperature software like riva tuner, or gpu temp. A faulty monitor wouldnt cause programs to freeze. Also if it were the monitor the mouse would also have the same symptoms everything else is showing.
