I have just installed an intel core i5-3475s into my lenovo desktop computer. It is a k330b motherboard with an LGA1155 socket. Followed all steps to the best of my ability but when i power it up i get no display on my monitor. The tower turns on and the fans run normally only thing is i dont get a display on screen. I have tried to change bios setting to allow upgrades but i cant seem to get anywhere. Any help would be very much appreciated.
