Very cool video, I'd love to see more. I have now also bought a DDR debug stick and a new linear power supply with 40V 20A. I have been repairing electronics for several years and also for customers. My equipment therefore amounts to approx. 3500€ with some very good tools such as a Fluke 175 as well as an Eakins microscope and an Atten Hot-Air Station and an Achi BGA Station. I mainly like to take on GPUs/laptops/MacBooks and smartphones/tablets, but I'm still getting used to motherboards. I'm now also reading a book to teach myself on the side. Best regards and have a nice weekend 😄 Tobi

That is some great Equipment, exspecially finding a beefy linear power supply like that! That must have cost a fortune! What is the book called and is it about Mainboards or generell electronics! Cheers

Great video, waiting for more motherboard repairs :)

[@lucataszarek8782]

Hello, a very nice and educational video, could you tell me what you plugged into the ATX connector?

[@MainboardMedic]

There will be a video about that! Its an 12V to 24 pin adapter! So you give it 12V and meassure the current of the 12V. The adapter has the other voltages like 5V.

@@MainboardMedic OK, thank you for the information, you did it?

[@MainboardMedic]

No its bought online, there is a link in my video description!

I have a Ryzen 9 3900X with GPU PCIe 16X not working, and it also freeze if "Global C-State Control" and "Cool n Quiet" are enabled on BIOS. The cause of failure in my Ryzen CPU was a DisplayPort cable with Pin 20 enabled, that caused a shortage with the monitor giving voltage trough the Pin 20 directly to the GPU and CPU.

Thank you very much. I like each of your videos!

Broken solder on the pcix slot?

[@Arachnoid_of_the_underverse]

Hi please could you repost your links for the post test cards you use as the present links dont seem to work for me, thanks.

[@MainboardMedic]

Ive checked the link and it still works for me, might be not availaible in your region!

Can you fix a gigabyte H310 ma 20 motherboard with a few bent CPU pins?

[@MainboardMedic]

Hey, i can do that but only bending them back and that is sadly not a guranteed fix! Sadly i cannot replace sockets as off yet!

[@BrozFix]

About PCIE post card TL631 Pro is it worse than yours TL611 PRO? And excellent video.

[@MainboardMedic]

Ive got to be honest, ive no idea haha

[@newhoshos]

hello bro can you guide me to solve my problem with my rog strix. x570 e gaming ,its does not boot , when i pres power bottun the psu on off 5 time

[@MainboardMedic]

Sure, do you have anything like post codes or LED´s?

[@Dandan-tg6tj]

I understand you have a problem but honestly, you ask for advice to solve your very complex problem from someone who does this for a living. It is his job. He does this for money to pay his bills and his food. You need help? Pay the man and he will help. Anyway, if you know nothing about motherboard repairs, you definitely have no business trying to repair one. It may look easy but it is definitely not easy.

thank you

Nice video and a great channel, the 55 timer video was amazing. It seems you are from Russia, right?! Given the popularity of X79 and x99 Chinese motherboards there, could you do a video modding one of those to beef up power delivery to the CPU? Ive got a x79 huananzhi and I'm looking to mod it for an oc past 4.2GHz, but all the material is in Russian. Translators suck. Edit: I assumed you're russian because you pointed in the 555 timer video to a video in Russian, but seeing your windows in German don't make so sure.

[@MainboardMedic]

I can see where the confusion comes from! I am in fact german, but my parents are from russia and taught me russian. Can you link me the material, i might give it a look. Nothing ive ever done before!

@@MainboardMedic there's this video in youtube watch?v=cAXAQ41yi60 but I also wanted to do something like biuldzoid did in this video here /watch?v=yi6w1TfZ3uM

[@JamesFox1]

Anytime you Have a Lesser Compute power GPU than specs of a Main board = you Must first start out in a lower x slot , as if 16 being the tope slot next lower is usually a 8x and or a 4x / 4x receivable signal reception And Many newer boards = there is no direct 4x on a 8x slot any longer , grab a single 4x auxialry slot but evven those are at 8x and Up now for 4k capture cards and Certain audio inserts

[@jimle22]

Why he doesn't connect the cpu fan?

[@MainboardMedic]

For trying to start it up it doesnt matter, because the 2200G gets barely hot and even if it would get hot it would regulate itself to not get damaged!

[@Waseem32139]

Please share schematics for other motherboards that you have

[@MainboardMedic]

There are quiet some Discords that share these shematics, you should check them out: Electronics repair school Learn electronics repair They both have youtube chanels and both have Discord Servers with shematics!

I have never seen such a tiny CPU heatsink in my life ever...😂😂

That is acutally an old school CPU cooler and that was more then enough back in the day!

[@nickvirgili2969]

I want one, nice little tester though i dont know how well it would work with a 13900k so...

You must not have been into computers in the 80s - 90s!

[@MasterJediSean]

5 beeps is definitely a GPU Problem. I suspect the top slot is missing a cap or something,

[@andreicipriangradinariu5529]

Do you repair? I have a Tyan S5537 would make a nice video..

You can contact me via my Email adress in my description!

Oh, he Had to upgrade, yup.

[@del4you2]
