Hello all, please be patient with me as this is my first post.
After a two days of troubleshooting, I am stumped with fixing my Maximus IV Extreme, which has the Q-CODE "00" and the CPU_LED illuminated in red.
Here is what I have tried:
*Tried three CPUs (3770K, 2600K and Celeron G530) - the 2600K and G530 need BIOS revisions after the one that came factory installed (Version 2001).
*Tried lots of memory, which is on the QVL - and tried without memory, all of which caused the 00 code.
*Tried three power supplies - even the one from my main rig.
*Tried system out of the case on the box - no luck.
*A 780Ti (has been working in the rig for a while now) a 6770 and a GTS450
*Tried both BIOS chips - both cause 00
*Tried USB bios flashback, BIOS seems to update OK, but error 00 persists after cycling power and clearing CMOS several times.
*I have inspected the CPU socket for bent pins and all seems OK - have shone a torch on the pins and cant see any bent pins.
I presume the culprit is most likely to be the motherboard as I know all of the components I have tested with are known working items from other computers - I would process an RMA but I cant find my original purchase date - so I cant register it (besides, I have a feeling that it is out of warranty anyway.)
Any suggestions are very welcome 🙂 Cheers for your help.
BTW - Sorry if I have posted in the wrong place...
