I have just installed a clean version on Windows XP 64-bit on my computer. Every worked fine, i logged in and no problems. I restarted the computer just to make sure everything is good before i start installing my drivers. The first thing i installed was my chipset drivers. It prompted me to restart, so i did. Once it restarted, everything was fine, i selected a hardware profile then i got to the login screen. Once i get to the login screen, by mouse and keyboard do not work. I restarted again, selected hardware profile, go to login scrren, and the problem was still there. What could of happened?
