First of all I put a gig of ram in my laptop about three weeks ago. So now my total memory is a gig and a half. About a week ago my computer started running really slow. I pushed control-alt-delete only to find that my cpu was running at 100%. It hasn't stopped running at 100% and the fan on the right side of my computer seems to always be on. When I installed the ram into my laptop all I did was put it in. Did I need to change anything else and is that the problem? I ran my virus software and it didn't come up with anything.
Here is a pic of my task manager when I just have firefox running:
Secondly, I started my computer today and I was prompted that my ati2dvag display driver was not running normally. Is this related to my first problem at all and what can I do to fix it. My computer told me to just reboot it, but this is the second time that this problem has happened. How can I fix this problem?
