Lately whether I'm using the computer or not, the second monitor will go black and my system will lock up. The taskmanager is at 100% when it locks up and I can do nothing but manually turn off the pc. I recently installed windows xp pro on the system because I got a new hard drive. Also, a couple of weeks after that I moved some cables around in the case to make things look better. Could that have something to do with it? Any ideas would be great, thanks!
