I am getting lag spikes for call of duty and UO every 2 1/2 seconds. I need help determining the problem and finding a fix. I don't even need to be in a game to get the lag; I could be in the main menu, and the game mouse 'freezes' for about a second and 2 1/2 seconds later, it happens again. I have a Pentium D Dual core processor (2- 3.6 ghz) and 2GB of RAM. I'm thinking it has something to do with the 2 processors and compatibility. Also, I used to play this game on the same computer a while back (like 6 months ago) with no such problems. I stopped playing it for a while, and when I start it up yesterday, I get said lag spikes. I forgot to add; My video card is Nvidia GeForce 7900 GT/GTO If any additional information is needed, just ask. Thanks.
