[Solved] No Display After Upgrading CPU

Upgrading CPU May Require BIOS Update

I recently decided to upgrade my budget gaming rig. The first thing to go was the dual-core Intel Pentium G620, with a bump up in processing power to the 3rd gen i5 3570k. Switching out the processors was the easy part; the problem came when booting up the machine to find no video out at start-up. I tried several different displays and video ports with no luck.

After reseating the old processor and regaining the display, I did some ‘Googling’ and established that my motherboard, the Gigabyte GA-H61MA-D3V, needed an update to its BIOS. It was purchased new and the BIOS version was showing as F1. To facilitate the move from dual-core to quad-core required an update to at least version F4; Gigabyte’s own website showed the updates had actually reached F6.

The quickest (and safest) way to upgrade was via @BIOS, a windows based software solution that avoids having to click through motherboard menus. The entire process only takes a few steps:

  1. Download and run @BIOS
  2. Download the latest version BIOS for your motherboard (in the case of mine, it was F6)
  3. Install the update (the software is very simple)
  4. Restart your PC and pay attention to the boot up screen – it should show an updated splash screen
  5. Shutdown the machine, unplug all cabling, ground yourself (preferably with a bracelet) then reseat your new CPU.
  6. Boot up your machine and everything should be in order.
