I bought a new motherboard ( asus P5PKL-AM SE ) and new processor core 2 dou e8400. I assembled everything started my computer let it started for 5m then I restart the computer to install windows 10 everything was going good but when window showed getting ready it restarted and showed cpu overheat error. my processor fan one leg is broken other three are perfectly fitted. I applied almost 2 drops of thermal paste.
