This computer was working fine witht he graphics card in it (128mb cheap but works) and i overclocked (bored outta my mind) and it restarted on its own one time , well it restarts/starts fine but right after the Xp Loading bar is done it shows the mouse fo a split second then monitor shuts off and goes blank(not a monitor problem)...and when i put my other graphics card in(very sad 32 MB) it works fine. I dont think the over clocked GC is broke ,cause computer starts fine untill after the Xp loading bar/startup
