Gigabyte Z77X-UD5H problem

hi

i have owned this for a few years now and was all running fine, o'c'd my i5 without a problem but i think it might be had it!

i went to power it on tonight and nothing so i thought PSU. changed for a 550 wt gold psu i have kicking around and switched it on and the mobo powered on and the antec 1250 fans spun up and the diagnosis LED showed db as the error code which i think is D6 which in the manual is no console output devices found.

i have done this:

unplugged everything and took the GPU, soundcard out of the pc and unplugged all dvd and blu ray drives and all the hdd. turned it back on and all the lights lit up and the same error code. is the mobo gone and time to upgrade and sell the CPU etc??

Power off and flip the switch to boot from the backup BIOS to give that a go..?

Couldn't it also be GPU related.....? Could also try the onboard video.

My Z77X-UD5H stopped booting and had the D6 error code on the motherboard. I was trying to boot from different memory sticks when the error occurred. Resetting the BIOS didn't help. I took it outside and blew all the dust out of it. Then I took out the old battery and measured it at 3.00 volts. I put a new battery in at 3.24 volts. Now my Z77X is booting again! What fixed it? I don't know for sure. Why did it stop booting? Don't know.

I've just realised, the actual post is from 2015. :cry:

Looks like he's updated his PC since judging from his sig.

I have the same board. I had the D6 error every time the CMOS battery was too low usually every 2 years or so since I turn off the PC when not in use. I'm now getting that error every 2 weeks. I suspect I have a parsitic leask on the motherboard and am mow upgradig the PC. Change the CMOS battery and you shoould be OK.

Hmmm, after reporting that it booted, it moved on to another error... it would boot and show the Fx function keys on the bottom of the screen, but it would stop and not accept any key presses. Resetting the CMOS seemed to work a few times to get it to boot. Finally it wouldn't boot, stuck at the Fx key screen. I eventually toggled the bios switch to use the backup bios, and viola, it booted fine to bios version F14. I started the Q-Flash procedure to update to F16j, and just before flashing, I toggled the bios switch back to main. It flashed it, and I'm now happily running F16j without problems. Long story short, it appears my bios was corrupted. I noticed all the boot device entries had been erased, I was previously trying to find a way to do that. I guess the only way is to re flash the bios. Now dual booting macOS Catalina and Windows 10 off an NVMe PCIe sn770 drive. Sweet.
