GIGABYTE GA-Z77X-UD5H can't shutdown

[macx8664]

Hi,

First of all, I can't send it to RMA since I bought this MB in june 2012... wow it's been a while.
I was not using the computer, my wife was and she basically let the computer always on during 2 years (which in that case worked all right)

So I have two problems with this computer (that are probably linked) :

1) I can't completely shutdown the computer. The cpu fan, usb port, power from HD and DVD, everything stay on. The only way to shutdown completely is to use the PSU switch at the back.
2) Both backup bios and main bios are ok BUT sometimes at boot I end up in a UEFI boot loop with this screen.


Those 2 problems happen with different version of bios (I was using F14, now F16), my settings or the default optimized ones. I already cleared CMOS, removed the battery...
I also try to unplug everything... keeping only CPU, 1 ram, no sata, no usb connected, using the power button on the MB directly... same result.

Unfortunately I don't have the hardware to test a new PSU or my current PSU (HX650) with a new MB...

What should I try next ? Is there a way to identify if it's the MB or the PSU without using any other hardware ?
The PSU is probably not the cause of the boot loop...

Any thoughts ?

Thanks a lot

OS and OS installation mode please
Meanwhile, each time you reset CMOS with black push button on the board (or other means) you have to load optimized default settings, save, reboot, enter bios again, set other parameters (specially OS Type and UEFI settings), save reboot.

Hi Teddybehr,

I followed your procedure to reset the CMOS but it didn't help.

So for the OS, this computer has been running mac os X 10.8 (hackintosh) but I didn't mention it because it should not be OS related because these days I'm testing it without any OS at all. I unplugged all the SATA connectors.

So I have only ATX 24-pin [20+4], EPS 8-pin and CPU fan connected. I even tried without USB keyboard and DVI but it's the same behavior. Even without any ram, as soon as I hit the switch on the back of my PSU, the CPU fan starts and the BIOS lights start blinking like that




Oh and just one precision about the boot loop :

I only get boot loop if shutdown and restart (but not always).
But if it's running and I try to reset. It's all good I never get the boot loop.

Thanks,

Re: GIGABYTE GA-Z77X-UD5H can't shutdown

I just found out that I bought this MB 2 years, 11 months, 21 days ago and that the warranty is 3 years !
Maybe I should grab my last chance to send it to RMA...

I'm gonna call Gigabyte support tomorrow !
Better late than never ;)

thanx, Precisions are appreciated.
Have you tried this one:

https://www.mediafire.com/?r75hbik8111zi6h

It s F16g (beta bios)
Put the BIOS file on a non-bootable FAT32 formatted USB key.
Flash with Q-Flash
- Press the "end" key multiple times to enter q-flash on booting.
- when the 3 seconds reboot count-down is finished after the successful flashing, the computer will shut down, remove quickly your USB key, the computer will reboot
- The computer will boot to BIOS
- Go to advanced settings
- Load optimized settings (F7 I think)
- Save, reboot, re-enter BIOS
- Finalised your settings, save, reboot

That should to it
If not, Gigabyte technical support should be able to help you
regards

Re: GIGABYTE GA-Z77X-UD5H can't shutdown

Thank you Teddybehr !

Unfortunately it didn't help with my problems BUT I found something very interesting...
You know that image I included in my previous post with the blinking lights.

When the computer is shutted down, those BIOS lights are blinking... and I just found out how to reproduce that boot loop !!!!
So basically if the switch is on Backup BIOS and I hit the power button when the light is on main BIOS OR if the switch is on Main BIOS and I hit the power button when the light is on Backup BIOS -> I get the boot loop.
I have to sync the blinking light with the switch and then it boots normally.

Do you think my problems could be related to the PSU ?

Strange indeed.
Have you tried settings manually memory settings (no XMP)? or with only 1 stick of memory?
Setting "OS type" to "other OS", disable secure boot and enable CSM support
This problem seems to be very common. There is many post on TT forum (or hackintosh forums) about that. Some report using BIOS F15q did it. For other it was setting the clock to 100.1, or the PSU was faulty, for other the board.
I guess it will be a trial/error scenario.
Maybe Stasio or Acebmxer or Wazza or Profjim will check your post and have better and faster solution.
Contact Gigabyte support
I will continue to scan for solution and follow the post.

Re: GIGABYTE GA-Z77X-UD5H can't shutdown

Not 100% sure, but try this:
Put only 1 stick of RAM in DDR3_1 slot (furthest away from CPU), and try to enter BIOS.
Make sure the RAM frequency matches the spec of your (slowest) RAM stick.
Also make sure the timings of A channel and B channel match the spec of your (slowest) RAM stick.
Frequency should be somewhere like x16 (1600MHz).
Timings (on both channels) should be 9-9-9-24, 1T or 2T.

Press F10 to Save changes, and reboot.
If your computer can boot normally with that 1 stick, then shutdown completely (switch off from power supply), and add another matching RAM stick in DDR3_2 slot (the 2nd away from the CPU).
Now the 2 RAM sticks will work in Dual Channel mode.
If you have 2 more RAM sticks, then populate the remaining slots. Just make sure that each set are matched. Best to have all 4 matched.
Hope that helps.

Re: GIGABYTE GA-Z77X-UD5H can't shutdown

I would be testing a different power supply to see if it would fix the shutdown problem.
As far as the boot loop, I gave up trying to fix the issue. My GA-Z77X-UD5H has been doing it since I bought it nearly 3 years ago. I've been repairing/working with computers since 1968 and I've spent a lot of time on this issue but I've never found a permanent fix. Motherboard replacement would likely be the solution, but I've put up with the boot loop which happens 3 or 4 times a month, so I didn't bother. (My computer gets shutdown 2 or 3 times a day) Other than the occasional boot loop this has been a good board.
