UPDATE: I did revisit this system, but I didn't feel like it warranted another video. Here's what happened: 1. I updated to the beta BIOS. Everything broke again to the point of no-posting and power cycling. 2. All attempts to invoke the backup BIOS failed. Tried shorting pins 1+6 on the BIOS chip while turning it on, no luck. 3. I manually programmed the beta BIOS and that fixed everything, including UEFI VBIOS. So we would've been 100% of the way there if I'd gone for the beta BIOS in this video, but also I still had no luck with the other suggested methods. Either way, it's all fixed now!

This channel is great. Just straight troubleshooting issues. Most of the big PC tech channels do this rarely. Its great to have a channel largely dedicated to this.

Great videos coming lately, really enjoying watching 'em! :) I actually found your channel by searching guidance for bricked b450 motherboards as my mate had a bad bios flash and the board was basically a brick at that moment. After watching the b450 aorus video fully and even the in-depth video about the flasher tool, I ordered one for myself and after a lil bit of searching for some more guides I managed to save the board. :D

Just finished watching the newest Star Wars before watching this, I enjoyed this twisty one more, lol

Really enjoyed that! Learned how to take reasonable steps to diagnose and to be patient and willing to try different things. You are making great videos lately! Thanks very much for teaching me. Seeing the ref lash of the bios was helpful as well.

It's great to listen to you think your way through problems, even accepting partial fixes when it's not going to customer :)

Just subscribed... Just working my way through your previous videos... Really enjoying your in-depth troubleshooting techniques and your thought process for this one ... Keep the videos coming.

Good knowledge base, logic and analytical, recognized that, watching couple of your videos.

Best on-line resource ever. Very much appreciate your camera work and your ongoing trouble shooting narrative. Well done!! Cheers from Canada!

"A good old GTX960" you makes me and my 550ti cry with that statement.

An interesting journey in this video. Had me worried for a while Graham, especially when you couldn't figure it out. I was saying to myself, "This is not good, Graham always figures it out!" Glad you're happy with the results. Thank you, always a pleasure to watch you work.💻🖥🔌⌨

Good work, champ.. I'm really getting more knowledge every time I watch +1 video of yours, thanx a lot man ❤️

Wow, that was a really interesting one. Thanks for showing how that EEPROM flashing stuff works. I am fairly good at PC troubleshooting but when it comes to taht kindof stuff I am still hesitant. I would have probably written this board off. And I still got a few boards sitting here, some for testing some for repair, that will probably not end up in the bin now.

Having worked with SPI chips on TV and laptop board for a while now myself, I can confirm indeed that in-circuit reading doesn't work and I don't even bother - I just desolder the chip and leave it alone as it is on the table. I grab a new, blank chip and mess with that instead, especially if the device is working to some extent and I don't want to mess with the little life it's got left which may depend on the chip I just removed. This also confirms that the chip itself is not at fault, though it almost never is - what's actually on it gets messed up. In the case of TVs, it's caused by bad, noisy DC coming from the power supply once its caps start to fail. Happens on Samsungs all the time, esp. old LE series ones. Love your stuff - your style is similar to mine. Cheers !

Very interesting video and you just never know what the cause might be so it pays to be patient in the troubleshooting process. Thanks for teaching us!

I really enjoyed this video, all the troubleshooting steps up to flashing the chips. I quite fancy playing with BIOS EPROM chips myself, that stuff was fasinating.

That is sheer perseverance. I would have ditched the board after trying all the components and a fresh power supply. I have flashed an Eprom but without success and that put me right off.

Ok, that was really interesting! Not too many do repairs that level so keep up the good work! : Oh and it's not too long. I'm used to 2 - 3 hours long :) Subbed

with Most of giogabytes older boards (i think new ones too) if the Main Bios EEPROM is corrupt but to a point it cant hand over to the backup (which most models its main function is only to reflash the main) if you short pins 1 & 6 on the Main one, you'll force it to trigger this Recovery and reflash the main BIOS eeprom.

i love your work ! ive learned so much! thank you so much adamant. worth it watching your videos!

After watching this video I think I ought to get a bios programmer and learn how to solder. Bloody amazing work. I'm thoroughly impressed.

what a crazy outcome. I definitely did not expect this!

As a newbie to computer repair I love the channel keep up the good work love watching I am a young 64 year old .

Another great video, kept us guessing as to what was the fault !

Thanks for sharing all this knowledge with noobs like me.

Troubleshooting PC's = eliminating possibilities. This video is the perfect example really. Also perseverance pays off? No better lesson than that for any technician.

I enjoy watching your videos.

An easy trap to fall into is putting your build into the case when it appears OK BUT I've adopted the 'soak test' principle where I leave it out of the case for 3 days and regularly test the system ie that it posts, it runs OS fine et Thermals obviously out of the box should be a little higher depending on the temp in the room et but the main focus here is that it works fine and has over the three day tests. I do admire your tenacity re this old mboard as truth is generally most fail because of power outrages - clean replace the power and they can work fine, dust of course in old power supplies is murder and I am sure this guy has seen plenty of those where you clean em and its like having a mini dust storm on your hands. Keep up the good work buddy ☺‼

These videos are helping me to stay away from Gigabyte motherboards.

Hi adamant motherboards can be unpredictable they cease to amaze us humans just recently sub to your channel on PC hardware are really good and full of tips and tricks not just hardware software as well keep up the good work.

IT at its finest work through it and when it works just take it and roll with the good times.

That moment when I see on the thumbnail H61, and pronuncing the H as haitch /ˈheɪtʃ/, is when I know I've watched too many of your videos. :D Jokes aside, I'm glad that I've come across with your channel, keep up the good work.

Great Channel. I'm a subscriber now! Love it! Dutch regards, Nico.

Fantastic videos mate keep it up

really enjoy your description good work

I live in Brazil and i admire your channel, is excelent

I think it has dual bios just follow steps: 1. Unplug any hardware (recommended), only Monitor and Keyboard 2. Press Power Button, but HOLD. Computer will start, after a few second. Wait until computer back Off, and release Power Button. 3. Press Power Button again 4. Computer motherboard will update BIOS Corrupt automatic. Wait until finish and computer will turn off 5. Now Press Power On again This way I fixed many free given Gigabyte motherboards from people which thought its need to be in the trash can. Or almost for nothing sold desktop pcs, because of corrupted bioses. Other vendors also has bios backup but it also depends on motherboard models. Btw I forgot to mention you don't need physical switch, just use manual provided by vendor, btw I found your videos recently and its very entertaining and full of helpful information.

The problem with the output has to do with EFI and the GPU bios, had this problem once with a R9 290X updating it’s bios fixed it.

I admire you so much for your persistent nature to get something working truly it is nice to see. that being said time vs £ probably would been better after 13 mins just paying £25-£40 (for £40 you can get a working GA-H61m with a working i3 processor on it and cpu cooler just fyi). I love pc repair I just think it needs to be said the money per hour imo is just not there especially when you in your own words didn't even think it would work. one can easily end up down a rabbit hole of 5-6 hours of work where £30 for a new part would guaranteed to solve the issue. don't get me wrong i respect your doing this for curiosity and fun just think it does need to be stated.

love the vids buddy!! im troubleshooting a dell t3500 mobo kinda doing same thing...was working...went to my girls for a da and came back and battery problems then next day no picture....tried different batteries...ram...power supplies cpu,,,still no pic...even used onboard usb to do the data to a external mining gpu pcie slot n didn't work...when I jump the 2 power pins it wont boot now but if I touch the rtcrst jumpers with a screwdriver itboots the cpu fan but fans don't spin on a rx580 n no pic...and on a 1gig ddr2 old card the fan does spin but no pic...not sure im feeling like a bad mobo...but love to watch your vids man!! definitely helps on ideas n troubleshooting..keep up the awesome work!!

I'm suprised this worked out. The last Intel mobo I dealt with, a 965 one which was even older than yours, didn't use straight serial flash dumps for the update process. The bios update files provided by Intel instead did use some UEFI structure with parts that were written seperately into specific areas in the flash by an executable program included in the bios update file itself that gets executed by the bios on next reboot. Notably, the flash area containing device specific data like serial numbers and MAC addresses was not written to. It was pretty hard for me to deduce which parts from the file I had to manually write where to.

I don't have a need right now, but I have to get one of those programmers... Cool video, great troubleshooting! Just subscribed!

Great videos, nice background music

Love your videos bro

7:13 "Are we power cycling?" -- car sound outside ! " yes we probably are" LOL that sound !

👍👍❤ I love these puzzling cases!!!!

Before I bought this Gigabyte Aorus Z390 board I had been using the Intel LGA1155 motherboards. Nothing fancy but rock solid performers.

Thank you for sharing that was an inteligent move...

Reallu great videos.

Nice videos bro. Your like a teacher

Well done!

Remember most of Gigabytes dual BIOS motherboards without a manual switch will switch to the backup BIOS after it cycles through like 3 boot errors. Cool vid. I have a ABit AG8 uGuru (915p Prescott) motherboard that does the same thing.

that's an interesting video to watch this kind of motherboard is what we learn to fix right now in our country we need more videos on this kind of motherboards fix (H61-H81-G41) and we need the diagnostic side

I also always had some problems with the reading clip! Since the contacts of the bios chip are connected to the board and thus there are always some impedances between the contacts, the reading of the chip is barely possible! No matter the coin cell battery in place or pulled out, I never had luck to identify and read the chip correctly with the clip tool. A quick heat with the heat gun and removal of the chip from the board works for me all the time.

I have the same type of board; issues, power recycling, would not post, and no picture. Solution; graphics card bad, corrupted solid state drive, switched to onboard graphics, could not get into bios, pulled cmos battery to reset, one bios chip was corrupted, fortunately the backup bios kicked in, replaced solid state drive and was able to load windows 10. I have ordered the bios programmer, just in case I ever need it. (Great video)

Just a tip, those alligator clamp chip connectors wear out quickly from my experience, they have little plastic teeth at the tips that force the metal pins into contact with the chip leads and those teeth can get worn to the point that the pins will not make reliable contact. Another issue I've seen is that some motherboards may not have the proper circuit layout to allow in-place chip programming from an external programmer, and you have to desolder the chip anyway. In any case, I've been able to salvage many otherwise dead board by just reflashing the BIOS. It's crazy how much good equipment just gets tossed due to simple little problems like this.

I enjoyed that!

Back in year 2000...when fixing no POST, the first thing i did was to remove all the RAM, HDD, just Mainboard and CPU and power it up...If you can hear a series of beeps, then the mainboard, BIOS and CPU is good. Then it just the matter of swapping RAM and Video card to see which one is fauty and stop the PC from booting. And 80% would be RAM problem....and most of the time, the RAM not actually bad, it just needs something to discharge (or refresh) the memory banks ( very different from just cleaning the contact pins) and what is did and work all the time, was using a piece of the protective thin metal coasted paper inside a cirgarette pack, with the metal side wrap around the pins of the RAM module, moving up and down the pins for 5 seconds and put the RAM back on the motherboard, and it WILL work...

I've found that dual-bios boards can be easily resurrected by physically swapping the main and backup bios. After the swap, update the main bios (from the system itself, not an external flasher) and this updates the backup bios. The physical swap also helps incase the main bios chip is wearing out. Gigabytes in particular live up to the "ultra durable" title with this, they feel almost indestructible. Finally bad power supplies seem to cause the main bios to become corrupt.

awesome bios fix

I just realised you have the same watch as me. Thats cool

Congratulations on your stamina - I suppose whether this was worthwhile depends on how you value your time and how you think about e-waste. But a fascinating logical process anyway.

To read or write flash chips in circuit, it's a good idea to power up the board, and hold the CPU in reset, by jumpering the reset pins on the front panel button headers. You may have tried this already of course!

Super vidéo ! merci beaucoup ;)

your content is great. first time comming across it over the weekend... I have a HP Omen ryzen 7 1700 it started making beeping noises it power ups but nothing i don't want a £1200 paper weight

As an electronics tech, i would be looking at the on-board voltages (maybe starting with Vcc on the bios chips) This is an old motherboard with "inconsistent" behavior... My first guess would be a marginal (or noisy) supply rail.... Very likely due to an old capcitor (or 2)

which hot air work station do you use and at what temperature. thank you for the videos great work

You really did your best to fix the motherboard, it was a computer ghost.

Mounting pressure on the CPU for the garbled bios fix ?

I got the feeling that the monitor (or video capture device) didn't like the resolution/frequency of the video display when it was in BIOS setup. I wonder if a different monitor would help? Maybe an old CRT monitor considering how old it is?

If it works it works, good gob!!!

Can you perhaps explain how you manually reprogramed the bios? I am having this issue rn, i have beta bios and it posts but then black .

Did you clean the motherboard with any fluid, any days prior to the video? 70% alcohol will cause problems for days until totally dry under chips.

That was a twisty one lol. I had to use the built in display to see what was wrong with a mates machine. It worked and as i touched the memory strips one of them upset the display, thin lines appeared. I would not trust memory as far as i could throw it, err well lol.

Wonder if the garbled display is just some random video component coming desoldered from the board or just failing, like on an old graphics card?

lol, my jaw dropped when the bios showed up perfect in the end.. the magic touch of a finger was in place.. second thought to add, i think that when you re-flashed the bios, you should have unplugged your power.. to refresh your system.. which you did when you plugged all back in the case together

The problem with the garbled display might have been a grounding or EMI issue. If it had been a VGA connection I would have said it was a horizontal sync issue. I'm not sure if DVI/HDMI has a similar signalling design.

you are teaching good

HAY? Hoping all's well... First, I just cannot resist this.... you have RAM and CP-EWE ... and a HERD DRIVE... Back in the OLD DAYS, when I used to utilize EPROMs,the terms FLUSH and ERASE were interchangeable... BURN or PROGRAM were the opposite terms.. BEST TO YOU

Hello, I have a HP stream cloudbook 11 which intermittently / randomly shuts off without warning. The longest it stays on for is around 5 mins, and shortest is a few seconds. However, there was a period when it stayed on long enough for windows 10 to install and seemed to work okay for a while. The laptop does not have a fan and it shuts down even when the laptop is cold. the laptop shuts down even when in bios. I have tried the following but the problem persists: 1. checked the heat sink and applied a fresh thermal pad 2. Disconnected keyboard, trackpad, screen, WiFi card, etc Any idea where on the motherboard the fault could be? Thanks in advance

I remember a long while back I had a gigabyte P35 DS3R board that did that with certain types of ram, if I remember rightly back then the issue was to do with the ram and the fact that the ram voltage regulator was limited and was misreporting the ram voltage in the BIOS which caused leaving the setting to the SPD to end up with a bit of graphical corruption with descent ram, but swapping the corsair ram out to cheap units and setting the timings and voltage manually before shutting down and refitting the corsair units solved the issue so I left it at that

Hi bro i have the same problem and my motherboard GA-H61M-DS2 the bios not apear at all it's still on and off do thinsk shorting pins is good?

I have a Gigabyte Z390 Aurous Pro I recently update the BIOS from F9 to F12 and now my computer crashes back to the BIOS and is telling me to set the BIOS to it's optimum defaults. This seems to only be happening when I set the XMP profile to profile 1. So instead of the 3600 mem speeds I am only getting 2400. The HyperX memory is on the qualified list but it isn't working now. It worked fine for the old BIOS for maybe two years but now it's shit. Is it possible to roll back the BIOS version? I did not save the old version when I did the update.

I really would like to see that little gadget work

IIRC you can force gigabyte boards to boot from their backup bios in order to reflash the new one - I think you have to hold down the power button after clearing CMOS?

Hi Adam, i have similar problem boots to initial screen then switches off code 7575, gigabyte udr3 x58, thought it was pin on cpu motherboard, but makes me think ram or bios, driving me crazy.

I have a board that just power cycles off and back on. Where did you get your bios programmer from? Im tempted in trying this.

ah those old pop can heatsinks were fun

good video

Hi there :) Maybe you can give me your opinion on this issue I'm facing. I had a perfectly working rig running on: - ga-z87x-oc - i7 4770k - 2x 8GB DDR3 1600 I turned it off and removed the RAM in order to test another DDR3 1600 module I retrieved from a machine that was discarded because of a broken CPU. The machine wouldn't POST then, I thus assumed the DDR3 module was bad. (Turns out it wasn't) I put back the original 2 8GB modules but then the machine still wouldn't POST (error 15: "Pre-memory North-Bridge initialization is started") and I get multiple beeps. Did I just fry this motherboard? How? Thanks a lot in advance for your feedback.

GA-H61M-S2PV boards (like the one you've got) are prone to main bios corruption for some reason. At the school I work at, we have about 250 odd Zoostorm branded PCs where 2 thirds are S2PV and the other third has GA-H61M-DS2 boards. I've had a good couple of dozen of the S2PV boards go corrupt where the DS2 boards have been fine. I suspect cheaper chips were probably used on the S2PV boards as to why this may happen.

Had a bit of a chuckle reading the title... Still rocking an even older G41

I'm interested as to why you would not use a wired keyboard/mouse when troubleshooting?

Hi again, Adamant IT. What is your temperature and airf flow level when soldering and/or desoldering chips from the ATX and/or Laptop Motherboards? Also, what is that software do you use for flashing the BIOS?

I've got an old gen3 gigabyte board with an i7-2600k on it Z77X-UD3H. It will go into a blank reboot cycle on occasion which I can fix by turning the power supply off and back on. Then it acts like it's forgotten my BIOS settings. Once I've entered the BIOS and hit save it acts normal again for a few more cycles. I've tried reflashing the BIOS. I've replaced the battery and tested it and it's good. Not sure what to try next. I have tried a different power supply already.

“Valid backup ROM detected” That’s why I like servers

Nice video. Thank you! What's the recommended temperature for desoldering from motherboards? BTW, I remember when I used to play with EEPROM of routers, I had to desolder because the clamp would power not just the EEPROM but other chips when the EEPROM is still on the board so the data of those chips messed up the reading of the EEPROM.

In a situation like that I disconnect everything trying to force it to come with an error or multiple errors. Then while I'm reconnecting thing see if the error for I connected goes away and see if pops up with the real error or starts working again.

When I take out the bios battery I hold the power button on for a minute two or three times to drain all power from the board

not to surprised about the bios on gigabyte motherboards doing this at lest on the old stuff. my old GA-5SMM had something like this happened where half of the bios went missing for no reason, lucky i was bale to re-flash a fresh copy on to it.
