I upgraded from an i3-2120 sandy to a i5-4750 ivy today. It did its 2 restarts on the first powerup and the display didnt work. I checked everything and the ram was loose. I installed 2 8GB sticks of ram and the computer just kept restarting over and over again. i pulled 1 stick and it restarted two times and then everything loaded. its working alright now. Core temps are running around 32c per core. the motherboard is a ASRock B75M-DGS. im running win7 64bit. any ideas?
