After several power cuts in quick succession, my freenas box stopped booting. Powers on but no display. Have tried reprogramming the bios chip using a CH341A, seemed to go fine however made no difference. From a couple of dozen boot attempts, only once was there briefly a display. BIOS came up, then after a couple of seconds it went green and froze (see photo). Is there anything else I can try to confirm that its the MB at fault? Have tried a known good spare PSU. Don't have a spare 1151 socket CPU to test.

Check RAM too.
