Ok so this problem is driving me nuts. I use an old Compaq presario 2100 laptop with an amd processor. In the last 2 weeks this computer has been running like shit. Internet is slow as hell and the computer in general just lags. My cpu fan is always on, and the task manager says my CPU is at like 80-100% when I am doing nothing. So far I've: Installed spybot and ran a search and there were no infected files found I've re-installed the OS. I run a pirated version of windows XP pro that my buddy made. It has been working great for the last year. What could the problems be? What else can I do? Possible hardware problem? HELP!
