This is a weird problem. Yesterday everything was working fine. I haven't installed or uninstalled anything. Today, when I play Command and Conquer Generals or Battlefield 2, whenever I am moving the mouse, the game freezes completely. If I am not moving the mouse, the game seems to be just fine. I have tried the following: Updated to the latest driver for my mouse (Logitech G5). Updated to the latest driver for my graphics card (GeForce 6800). Ran anti-virus software. Ran scandisk, ad-aware, and Spybot Search and Destroy. I defragged my computer. I re-installed directx. I re-installed the game Generals. I have rebooted many times. I have monitored the GPU temperature (45 degrees). I am running out of ideas....can anyone help?
