Hi guys,

I have been using the K3 for a year now without issue, however yesterday I popped in a sound card into one of the PCIEX1 slots and the BIOS refused to find my boot SSD. After much troubleshooting I narrowed this down to 2 of the 6 SATA connectors not functioning (port 0 and 5). I thought it a coincidence with the sound card until I stumbled upon a review of a of z Gigabyte Z270 on a website that mentioned that installing PCIEX cards can knock out SATA ports on that board. The manual states that M2 cards will knock out SATA ports but not PCIEX cards.

Anyways, the main problem is that I cannot get my ports back. I have removed the sound card, reset the BIOS, but the ports are not working.

Anyone any ideas now to get these ports back. And if a PCIEX1 card should knock out SATA ports?

Pulled the battery ?

Not sure if @GIGA-Man has come across any issues
 
Does pulling the battery make a difference? Obviously since you mention it, just never come across this. I thought CMOS reset did it all?
 
OK pulled the battery and no difference.

However.... changed the cables again to new ones that I got with the MB and everything is working great now!

Well my sucess was short lived. Failed to boot again after about an hour. Literally pulling my hair out at this point!

So I took the cables out and noticed a small chunk of dirt wedged in the port. Took the hoover to the ports and cleared it all out. Cables in and we appear to be back in business. Not optimistic, but the dirt would maybe explain the random fails. I shall give it a few days and see what happens.
