I finally found a working pair of 1156 mobo/cpu, and the culprit was mobo. My cpu worked fine with the other mobo, but when i put the other cpu on my mobo, same thing happened.
So, i decided to buy a new set of 1155 socket, instead of buying a new-old mobo. And these are what i have decided to buy:
CPU: Intel Core i5 3470 (s 1155 , 3.2 GHz , 6 MB)
MoBo: Gigabyte Z77-DS3H (s 1155, Z77, DDR3)
I may decide to OC them in the future, but not anything hardcore. Just a slight upgrade
. Will they do the trick?
