Hey all, I've been having a problem with my notebook. I was recently playing a game on it when it froze all of a sudden. I couldn't move the mouse or anything so I had to reboot. It worked fine at first but once it booted to windows again it froze once more. I tried turning it on again afterwards and nothing happened, it was just a black screen. I thought it was overheating so I left it to cool down for a couple of hours. It booted and went to the windows logo but froze again. I have tried turning it off and on many times to no avail. When I turn it on the power light and hard drive lights turn green but after a few seconds the hd light is off. Is this a hd problem or something else? It is an HP Compaq nc6220 laptop. Thanks in advance.
