BleepingComputer.com: Aim Install Keeps Crashing

every time i try to install aim 6.0 or higher, my computer automatically restarts itself when the installer gets to about 50%. i have aim 5.9 installed with no problems but i cannot upgrade with any 6.x version. ive used nortons, ad aware, and spybot and i have no infections. i just recently used system restore to completely restore back to factory. this problem with aim was occurring before the restore and now its still happening. im so lost. any ideas?
