Ok so Im quite tech savy but have been stuck for awhile now.

I have three comps all with this motherboard
BOXDX79TO
https://www.newegg.com/Product/Product.aspx?Item=N82E16813121552

Same gpus, cpus 3930k, etc...
All three were running fine. I than sawp out the gpus for newer ones and now can not even get a post on either old or new gpus.

The post code is showing 00- 67-69 on boot than goes down to like 20s and gets stuck at 26. All three boards do the same thing. The ram, gpu psu and ssd have been checked on other machines.

Let me know what you think

This is a problem with boot device selection on older boards (seen it on sandy/ivy bridge running with new pascal GPUs)

Which GPU are we talking about, and are you using the newest BIOS version from 2014?

Flash the bios, and clear with battery pulling out , without power ofc, also press start button to clear all elec
