Gigabyte B75M-D3H corrupted BIOS boot/post loop fix 

If it was not clear to someone, I saw in another video that pin 4 should be bridged with pin 7 of the main bios with the board on, until a recovery message appears. Thanks a lot!

Worked for me! My computer was completely stuck in a no-post loop. Thought either my mobo or cpu had died, but this fixed it. Thanks for uploading this.

Thanks so much! It seriously works. You short pins 1 and 6 together on the BIOS labeled M_BIOS (which is the main BIOS) while the computer is off and have a friend turn your computer on while you're doing it. When it beeps, stop shorting the pins and watch while it recovers.

It worked. Short the Pins 1 & 6 near d white arrow - that is the clue... then push power button. Press Enter 2x... fixed... thanks for the tip!

Firstly thank you Charlie, i had the same issue with my Gigabyte z77-D3H and nothing could fix it until i stumbled across your video. your trick fixed my 3 year old motherboard. Thanks for sharing Charlie

Took a couple of attempts but worked a dream. I really thought this board was bricked but now working as it should. Thank you so much for posting.

I just fixed my z68-ma-d2h-b3 using your method and look at that. Big props to you finding this fix!

Wow I gotta say my guy this actually fixed my problems. I was getting so hella desperate to fix my rig cuz im actually about to move and I DID NOT need something like this happening. Thanks so much for your vid and slow pace explaination !!

Thanks for this! I have been trying to fix my aunt's computer with this board (I offered to build a new one, but no she wants old and busted back) and had tried literally everything else in the board manual. Figured I didn't have anything to lose by following your suggestion of shorting the main BIOS and boom, it's switched to the backup and booting properly.

Seen in other videos telling you to short the pins but none with the detail (LOOK FOR THE ARROW) good stuff thanks

After the third try, I finally got this to work on my H87M-D3H mobo that suddenly went into a boot loop for some unknown reason. Appears to have fixed the problem. Thanks.

It's 2023 and you are still saving lives man. Pin 1 and 6 took a few tries and it worked. I'm writing this as my backup is writing back my main bios. And this happened to me because I updated my bios from f14 to f15. Do not do it.

You are a lifesaver. My Board had the same exact issue and believe it or not your fix actually worked. I can't thank you enough.

Thank you so much bro! Worked after a few attemts, pin 1+6 was the key. You saved my weekend :)

I know you warned us not to try this, but my main PC's board was dead for over a week now, the same malfunction you had, so i decided to try what you've done, and it worked, i'm writing this comment on the same PC that was dead few minutes ago... Thank you very much, i really wish i could give your video few more likes 💖💖

Wow you are a genius! I use the same motherboard and ran into this situation yesterday, and lucky enough to see your video right away, and it actually works :). thx man, now I gotta backup all the important stuff.

I found easier steps for anyone having corrupted bios on GA-B75M-D3H motherboard, make sure the computer is turned off and then press the power button and reset button at the same time for 10 seconds and the back up bios should kick in reinstalling main bios. for some reason after I installed update from windows 10 which is 1803 update as far as I can remember, it gave me a blue screen and then corrupted the bios.

I wouldn't have believed it myself if it didn't work but yep, I jammed a paper clip into my M Bios' 1st pin and it broke the loop and my PC is working beautifully again. Thank you Charlie.

Awesome! You saved me from a lot of hassle. Because this chipset is old I would need to get a new motherboard as well as new ram and a new CPU.

Thanks so much! Nothing I did worked, except your solution.

Dude youre a legend. Thx for helping me fix my motherboard

I tried this myself and it wouldn’t work at first. But after several attempts at shorting the bios chip it really actually worked. I am amazed. Thanks so much. Update: Not working after rebuilding pc.

I managed to fix and old board of mine after doing this for a while. Thanks for this, nice work!

Worked for me, thanks a ton man! I just randomly shorted pins till the repair screen showed up lol, should of read comments xD

This also works on my Gigabyte Z270mx Gaming 5, thanks for saving tons of time!

Wow! Lifesaver. At first I tried shorting the m-bios on 1 and 6, but nothing happened. Then I tried 1 and 2, but still nothing. So then I just got pissed and started wiping a zip tie along all the pins and sure enough, there is the secondary bios recovering stuff. Phew.....

It's one of those fixes you cant quite believe until you see it W O R K S ! ! !

you got a very control on your hand mate, pointing ics with bare screw driving on electric powered motherboard.

Guys i tried everything from resetting cmos, taking the cmos battery out, taking ram out, disconnecting HD's and sata cables and NOTHING worked. Until i came across something that worked for me and got the bios working again. Turn off power supply. Hold down the on button. Turn on power supply then after 2-3 seconds of the computer being on, turn off the power supply again. Then release the on button. Then turn the power supply back on. Now press the on button. This will reset your bios and it will overwrite the corrupt bios with the backup bios. You will see a loading screen as it overwrites the corrupt bios. This is what worked for me. Everything else failed.

THANK YOU, TRULY YOU SAVED, I WAS THINKING ABOUT TO THROW MY PLATE TO THE GARBAGE BUT THANKS TO YOUR VIDEO SAVE ME A GOOD MONEY

Thank you very much for this. Finally it worked, but I had to try it 6 times... Anyway, it´s working now. Thanks!!

Thanks a lot! After a few trials - restarts, power on, power offs, your workflow finally was successfull.

Thanks, had this problem today, shorting pins 1 and 2 fixed it.

God bless you! I have tried all of the methods of resetting BIOS described in the manual of my H81, removing CMOS battery, shorting the designated CMOS-reset pins, holding and/or pressing both reset and power button, all without and with power, with no result! My bootloop / corrupted BIOS issue was initialized when I tried to test an old Radeon 5770 (Juniper) on my system, it started doing the post-beeps (which it never did before!) and boot looping exactly in that Gigabyte-patter. This is actually a VERY widespread issue with Gigabyte boards!! Practically what fixed it after trying just about every hardware configuration and reseating etc. and attempting to reset CMOS was just fiddling around on the PINs of the BIOS_M (main?) module, instead of holding it calmly, it did the same thing detect that obviously something was wrong there and it let me press Enter to reflash, and from then on it was back to normal. I did come across the idea of shorting the BIOS circuits as well, because after bricking my Gigabyte Mobo with it, I put it into another PC and I flashed a wrong BIOS to my 5770 Juniper AMD GPU (in order to fix horizontal lines I saw in all driver versions, instability etc.) and I had to bridge that from being read on the GPU by shorting 2 pins on a BIOS saving circuit just like that on the motherboard, in order to be able to actually start the system with the card installed at all, and then I had to use 2 graphics cards, (so because of that I used a third motherboard X-I) 1 for display and the Juniper for flashing, and the short had to be removed right before flashing. It was even more crazy than the BIOS reset. But I got some other BIOS installed and ended up confirming it was not fixable by BIOS. Now retesting this disgusting semi-brick of a bugfest Radeon 5770 GPU on my newly uncorrupted BIOS with different hardware, see if I can get it running bug free on here (but I don't think so, this is maybe an overheated GPU, corrupted memory or something along those lines) So just so you guys know, a bad GPU can actually cause your Motherboards BIOS to get corrupted just like that! The things we have to bother with...

well it's worked for you, that's good , but next time you need to know that gigabyte has a safer way to do that , you need to click on power botton to turn it on and than you click again but this time keep holding the botton for 10 seconds and than release it , and turn it on by clicking again power botton without holding it, and it's start automatically the bios recover :) peace

Worked like a charm, my friend. Thanks a lot.

i am in year 2022. Thank you very much You saved my computer. PIN 1 + 6 . NOTE: if you don´t know which are the pin numbers search for the BIOS integrated circuit model "mxic mx25l6406e"

Holy shit, it worked, I read somewhere about updates to the bios killing the mobo... so you destroy the main and have it back it self up... that is Stupidly genious... thank you

Thanks a lot, only your method worked for me, you fixed it.

Thank you so much! Pin one and 2 worked for me, then had to put new bios on again! Thanks again! =D

Much safer to power down then hold the power and reset buttons for 10 seconds. The Mobo then goes into recovery mode.

Thank God for you and youtube and the commenters :D pins 1 and 6 worked for me. Thank you, thank you, thank you

Man, I had a similar problem, and it worked. Thanx a lot!

Man, i dont know what happen in your mind to do this, but i tried it and work!!!! I love you

This worked for me. Kudos to you sir!

Thank you so much man had this exact same issue and it worked, had to do it a few times though you're a life saver!

I can confirm that shorting the pin 1 and 6 at the same time on the M_bios works on a Gigabyte GA- Z97X-SLI

Man It really worked for me too...thaks man

You saved my client pc! Thanks!

Worked like a charm on a AM3 + 990fxa-ud3

My god, thanks brother I was crazy with this damn problem with a key worked everything was worth it

Thanks for ur video ! My b85m-ds3h has bios loop and end up shorting m-bios pin 1 and pin 5 while the computer is on, it pop up the message about corrupted bios and do exactly like ur video !

wow!!! it's working very good tutorial..

holy crap it worked lol..thnk you charlie ..wow i was at the point of giving up and throwing motherboard away..did exactly wot u said and it worked haha..thnx alot for advice dude...😂

VERY BIG THANK YOU ! IT WORKS !!! AMAZING !

Thank you sir. You rock!

You're the man !!! I almost gave up on the damned board . It worked like a charm !

Ha! what the! I dont know where did you get this idea but it work! wow! thanks

I had tried everything else but failed. I have now tried this method but still not worked.

Works for me! You save me. Thanks a lot!

Thank you so much dear...it really works for me too.......

WOW...LMAO...That is some funny Sh#@! It worked perfectly - PERMANENTLY FIXED - Thank YOU. (see instruction at END) Orange Tech Inc. - 3 Full Days I've troubleshoot this motherboard BIOS reset issue. Exhausted every possible scenario including replacing the i5 CPU with i3 CPU and nothing worked until NOW. GA-P75-D3 Motherboard. I updated to F11 latest BIOS but still after booting to the desktop it would reset the BIOS when I hard powered off the computer. I would constantly have to do the dual bios recovery by holding down the power button when the computer immediately powered on 3 times until it came up with the recovering BIOS screen. It would work again with the F9 BIOS until I would shut down the computer and then it would reset the BIOS and loop again and again. It did not matter what BIOS update I did or even if I left the original BIOS F9 alone it always reset the BIOS and looped when the computer was shut down. I was ready to throw this motherboard out the window until I saw this GENIUS video. I then shorted out the BIOS_M (First) and OMG it booted up without looping. I tried to shut it down and reboot it and no matter what I tried it would NEVER reset the BIOS and boot loop again...LOL. I even removed the CMOS battery and cleared the BIOS by connecting the jumpers trying to get it to boot loop and reset the BIOS but it just kept booting up fine. This fix works awesome! It permanently kept the BIOS from resting and looping. To short out the M_BIOS I just took a screw driver and touched the 1 Pin & 2 Pin together while the computer started powering up. Once the computer shutdown, I removed the screw driver. I powered on the computer and it never reset the BIOS or boot looped every again. I believe the 1 Pin is the one that a white arrow is pointing to and the 2 Pin is the pin right next to it. The 1 Pin is at the very end of the BIOS chip. Thanks again for this permanent fix. (On a special Note - Being a computer technician since 1997 for around 20 years this issue was a technicians worst nightmare because the motherboard would work after the bios recovery for as long as you could keep it powered up. You could even flash the bios and update it to the latest and soft reboot as many times as you want. This is why us technicians did not want to just give up because we could at least get it running to some degree. But of course as soon as it was hard powered off the stupid bios would have to be recovered again because it would just loop and loop. Special thanks to this Charlie guy who never gave up until he tried one last thing "outside the box" so to speak and boom...found a work around fix. This is what separates the good technicians from the great ones. Nicely done Charlie! Nicely done!)

Hi mr Tech guy charlie... when you short the backup bios,the pc is: a.turn off (with eletric plug in) b. turn off (with electric plug off) c..turn on which option that you do at that time?

What pins did you short to be exact, I'm having difficulty with a gigabyte board that is also dual bios?

same problem in my case in 27-11-2019 in Gigabyte B75M-D3H

I have the same problem and do not understand what you said "shorted out the pins" I am a IT but have the same issue, somebody can explain me?

Thanks, I've heard that holding down On button and Reset button down together for 10 seconds would do the same ?

Hello, why is the bios corrupted like this every time my gigabyte b75m d3v computer is started? What do you think is the reason?

hi sir, can you show the fully video how you exactly do? i got a motherboard gigabyte z77m-d3h but still nothing come out

WHICH PINS DID YOU BRIDGE ?

You are my Hero !

My gigabyte z97x 7 doesn't post anything in either bios, it just says no signal, any help?

It worked! Thank you!

Big thanks mate..👍👍👍

wtf bro, it worked for my old computer that died a year ago. GG

Didn't work at all for me BUT as a last ditch effort I desoldered the BIOS chips, stuck B into the A slot, and it booted right up. I'm going to put A in the B slot and then reflash it. I have no idea why this dual bios system doesn't work switching to B properly. B was fully functional and yet the motherboard ignored it. Anyway, if it helps anyone - you can get a hot air soldering station on ebay for 40 bucks. Takes 10 seconds to remove them. Let it cool for 10 minutes before resoldering them. Oh- and they're rotated 180 degrees. Make sure to match pin 1 to the arrow!

Thanks it's work

BROOO THANK YOU SO MUCH IT WORKED FOR ME TOO

Which is the best processed for this MB my processor is dead now??

just wandering what "bios version did corrupt your current so we know what bios version should not get

thanks man! you are great!!!!

How to short pins? Plss plss reply really imp

Hi! hild on i do have that mobo but im very confused here?! so..i have to make the thing with the screwdriver with which pins?

didnt work for me... it keeps looping no matter what

Witch pins did you short circuit on M-BIOS chip??

I have a ga-z77x-ud5h and it has a switch next to the clr_cmos jumper that you can flip back and forth to select which cmos chip you want to load the bios from, main or backup. I accidentally shorted my mobo plugging things into it while it was still turned on which apparently corrupted the main bios but unfortunately it doesn't automatically repair the main bios when loading from the backup and now I have accidentally fried the backup cmos chip also the same way as the first and think im REALLY s.o.l. now :( yall be sure to turn off all power and unplug your power supply before you go plugging all your hardware back in so u don't end up in my situation!

i tried. it was updating and it restarted again then i never saw the dual bios again now it just restart all the time pls help

Thanks bro I fix now a H61 Board and I thing I save my other x58 system thanks thanks thank

This will help my PC shutdown properly? It's problem is when I shutdown the PC,the 4 case fans and LEDs remain on,so will this help this issue? And all the components needs to be removed,not only unplug from the power supply?

Im able to get to the step where ive shorted the M_BIOS and its stopped rebooting. It stays on but i dont get any screen signal. What is the problem?

Hi My friend, Do You know if this Motherboard allows working with 2tb ssd m.2 nvme via Pcie? Thank You very much in advance!

You really need more than 2GB of ram for windows 10, even 4GB would struggle and would be using the page file all the time and making the system very slow.

This help me, THANKS!!!

Oi, eu tenho um gigabyte sem dual bios, como posso resolvê-lo?

My board never beeps when shorting and doesn't start a secondary bios boot. Anyone else have this problem?

Turn on the computer by pressing and holding the power button. After a while it will turn itself off. Unpress the power button. Press the power button.

I have the same problem .. but it doesn't gets fixed by this method.

Which pins to short and which bios main or backup?

gigabyte b75m-d3h auto reboot after shutdown, please give solution.

I tried this and it failed. Now the AORUS screen doesn't even appear the motherboard just constantly reboots. The Z370 is a total loss now.
