Re: Asrock Z68 Extreme4 Gen3 no longer recognizing video card
Since it worked for 8 months trouble free this is worth trying...
With your monitor connected to the mobo IGPU -- Do a full CMOS reset by shutting down unplug the A/C from your PSU and move the jumper pins per your manual to clear CMOS then on boot up enter the UEFI SET DEFAULTS then make any changes that you had before for memory timings ect ect but no overclock and after your rig boots into windows disconnect your monitor and connect to the GPU and see if the card is properly detected.
If not then inspect the cards connectors and if need be use a fine eraser to gently clean the contacts and afterward wipe with alcohol to flush and dry the contacts. While visually inspecting for any tell tale signs of burning also sniff to ascertain if anythings smells burnt and retry the above.
