Okay i did recently install a new cpu cooler but when i turned my pc on (windows 8.1) it loads up correctly the on the windows 8.1 loading screen(where the white dots make a circle) it reboots instantly.Sometimes it says on the loading screen "preparing automatic repair" then is either freezes or reboot. i tried the reach any bios settings but my keyboard did not even light up. My pc was running perfectly before i installed the new cpu cooler but after that i had problems. I did force shutdown my pc while i was playing payday 2 to install my new cpu cooler now i have problems and people have told me my cpu was fried but i don't think it wouldn't made to the loading screen if it was fried. Please help me ????
