Whenever I click and drag something, CPU usage goes to around 35% and if I double click a folder, it spikes to 70% then goes down. When I move my mouse, it goes to 15%, but when idle, it stays normal 0-2%. Also, my mouse happens to freeze alot, then continues to work after a second or so. The light on my mouse would flicker and sometimes go out completely. I have run many adware/virus checks, posted my HJT log, and followed all the steps with no solution. I would appreciate some help on this because it is completely unacceptable for a decent computer (AMD athlon 2.4 ghz) to become this laggy.
