Hi all,

For the past four months I've been having problems with my computer. The overall performance of the computer is slower than it used to be, but most notably when I play Warcraft. I receive an error message stating I have low virtual memory and Windows will adjust it's allotment. Because of this, I lag out of games (both over the internet and when I am playing by myself without a connection). For the first two years of playing Warcraft this never was a problem.
Also, at random times when not playing Warcraft I'll get the Blue Screen of Death. The error is with nv4_disp, and whenever I get my computer working again I get a message saying there is an error with my video driver. I re-install the software and don't get the error message again for a little while.
Lastly, in my running processes I occasionally have two files called explorer.exe, which are not the same size.
I don't have any internet popups, I run Ad-Aware and Spybot biweekly, and do an Antivirus scan every morning.
Am I looking at a virus? How can I fix my computer's performance?
Thanks for your help!
