Question Bricked Gigabyte Motherboard

[carlisu]

Hello, first of all, sorry for my English and thanks to anyone that takes his time to help me. A year ago, I tried to do a hackintosh to my computer. At that time, I already had done one successfully so I thought it was going to be easy. I don’t remember well the entire process.

But I know after changing bios settings I got into a boot loop where I could see a blue screen with gigabyte dual bios logo, and after a few seconds it would reboot. I read somewhere that I should clear cmos shorting the 2 pins of CLR_CMOS. I did and know motherboard doesn’t do anything, it doesn’t show even the blue screen. Now, when I press power button,it is just powered for 2 seconds and then it reboots inmediately, in an infinite loop.

I saw that gigabyte motherboards with dual bios have a feature that kicks a backup bios and it’s able to reflash the main one. There are three methods to do this, two are with the power button but I can’t follow any of them because the pc is on for only 2 seconds and basically it needs to be on at least 10 seconds. The third method is to short pin 1 and 6 on M_BIOS chip to kick the backup bios. While doing this, I still get a loop, but the pc keeps on even less time, like half a second.

I don’t know id I am doing something bad while shorting, I tried a copper cable and a nose hair trimmer, but I always get the same result. I did the test with and without the rest of the components. My motherboard is GA-H61M-DS2.

Welcome to the forums, newcomer!

From what you're described, it's highly probable that both BIOSes got corrupt resulting in your no POST scenario. You could use a CH341A BIOS Programmer and then flash both BIOS chips with the latest BIOS version, taking note of which PCB revision motherboard you're working with at this moment of time.

I am curious though, you didn't include your specs to the build...
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:

CPU cooler:
Motherboard:
Ram:
SSD/HDD:

Hello! Thanks for your reply, I researched about that programmer and I think I will buy a second hand motherboard, the programmer thing looks seems to be complicated. Sorry for not including the specs. I skipped that because the problem was on motherboard.

why was you shorting the cmos and powering on at same time? yo should power of.. and switch of psu ,short cmos for 20 swconds (roughly) then switch psu back on and then power on board (no need to short cmos while doing this as that will cause the computer to keep restarting constantly)
