New CPU Freezing at BIOS screen then shuts down computer.

Hello,
Just received my i7-3770k(LGA 1155) CPU in the mail. My intentions with this CPU was to upgrade from my current i5-2500k. After putting in my i7-3770k(all pins are checked and everything is looking good), the computer boots all the way to my BIOS screen - and then just freezes for ~5 seconds then shuts down, and reboots. It loops like this until I shut down the computer myself.

Originally I thought I had messed something up on my motherboard(GIGABYTE GA-Z68X-UD3H-B3), but I put my old CPU back in and it booted all the way to desktop successfully.

    That cpu is only supported on that motherboard on BIOS F12- if you have F4, F8, F9, F10 or F11 it won't work. An
    i5-2500k will work on bios F4 and beyond. Hope this helps

    I did not update my BIOS - good call, rookie mistake. Will provide an update after this is done.
  4. Update Bios, on cpu support list says F12 bios for i7-3770k for your old cpu it needs a F4 bios. Judging by your symptoms you have F4 bios.

    It looks like that is indeed the case, but now I am running into the problem where the drivers provided from GIGABYTE on their website is 32 bit whereas I run a 64 bit system. Will have to look around the internet some more for 64 bit drivers.

    That's exactly what it needed. I ran into the problem of the drivers on the website only being 32 bit, however I used a program by GIGABYTE called @BIOS and it fixed and installed directly for me. Thanks everyone for the help.
