In this video we go over gaming motherboard Z97-G45 and while diagnostic we see that our chipset is "punctured" on two powers to it.
It felt like I was at a medical appointment. The expertise is insane, this guy is the computer doctor.
Would be nice if you could give sort of a checklist what to check when diagnosing a motherboard and what the approximate voltages/Ohms should be otherwise, Great Vid! big thumbs up from South Africa
When he says "Hub" he's referring to the PCH (Platform Controller Hub), older computers used a North Bridge and a South Bridge for Intel based chips. AMD had its own PCH called Fusion Controller Hub. Now Intel and AMD simply refer to it/them as the "Chipset", meaningless trivia but here we are.
thanks was lost being a intel guy for life was confused kept talking to the screen calling it a south bridge which I know now is wrong .
Didn’t know this, however to me, that clearly looked like the chipset. I’ve been calling it chipset for some time, but I do remember the north and south bridge, even older AMD boards had this because I’ve owned amd my whole life and I remember upgrading heat sinks on the n/s bridges. Though eventually I noticed newer mobos just had one bridge and they resorted to call it “chipset”
I seem to remember most chipsets back in the day after IO moved from a VESA slot of the '486s to the mainboard when pentiums 1st came out, both AMD and intel had a north and south bridge, later on around the time of the via KT133 chipsets AMD had a lot of extra speed with the magic pixie dust of the inter-chipset communication in the form of a dedicated ' hypertransport' bus, but intel was stuck at FSB speeds between the 2 chips , the oddball of the bunch was the SIS630/730 which was a single chipset that had everything in it, and for once it was a SIS chipset that didnt give a lot of headaches... and performed well enough for the time
@@DevilbyMoonlight Yeah, I remember that too.
Intel IDX2 (80486DX2)
thanks
You should place the camera overhead, so we can see what your'e actually probing... Its very hard to see what your're actually doing, for the 1st half of the video. Thanks for the videos anyway.. Keep up the great work!!!
I agree, please show us what you are actually metering, this way we can't see it.
I do agree with you but I have something to add.

Sit through a few of his streams and you will quickly understand the basic topology of mosfet power circuitry.
Another great topic to research is Buck Converter topology as this is essentially how your motherboard steps down the 12v to 1v and other voltages.
If you watch Eli Tech he is going from ground to the gate or collector of the mosfet to confirm that the entire power rail is down.
Since there is a short to ground overcurrent protection will kick in not allowing the board to turn on.
We probe in peace!

Wow. Troubleshooting a motherboard down to the component level is truly genius.
I'm impressed! If I ever need any repairs of this nature, I'll send it to you. Great work!
mate this is the best video ever, I have work on smd soldering for a year know, it's really satisfying how easy you cleanup the pads
As an electrical engineer, I really like your videos. Wish you would better show the diagnostic steps though
I love your work. I've learned a lot just watching you.
Awesome thank you, I'm a PC tech from Bolivia, never knew you could buy a Hub Chipset and re-ball it, and checking the voltages was great, we don't have anything like this over here
I could watch you repair electronics all day.
Nice video and hope to see more in the future.
Quick FYI:
Some desktop MOBOs can have a resistance of less than 50ohm on the 5v line (with nothing connected or inserted).
I have 2 Intel boards that show 52ohm and 24ohm on them and work fine. Th is can fool some people used to healthy rails showing 500+ on them.
My first desktop board repair had this. I spent 2 days searching for the 24ohm short on the +5v rail. Two days of prodding and marking data because, surely, 24ohm is a short. Always.
Nope. Got fed up just before taking the PCH off and tested it. Booted right up, lmao. Noticed more like it after that.
If it's showing 20+ ohm and it isn't taking too much current on power injection, it just may be good. Now, here the PCH was getting hot on standby. That's obviously a definite short so look for that but of it stays cool even with powerinjection, test it *FULLY*
(CPU, one stick of RAM, all fans plugged in, etc).
Astonished! This kind of knowledge is mind-blowing!
thank you for all your labor, im getting enjoy and learn step by step. choov
Thanks. That was actually potentially helpful. It's unbelievably hard to figure out the minutiae of not only everything that can go wrong with a motherboard, but what did, which is often first assessed by figuring out what didn't.
You found those power lines like a champ, I usually spend a couple of hours looking for the schematics I bought of some russian forum for 10 bucks!
Where do you buy them? I would like to get a schematic for Rx 480 gpu
@@DragonAndrija it's real rough, because I searched for a while on a bunch of different forums, it would be much safer to buy a parts board instead
This comments funny because it’s true 😂

Nice work! Came here for a DIY solution of troubleshooting but stayed for the entertainment
Keep doing this type of video. Very interesting and the step by step vlog is really nice
Whenever I use a multimeter, I just blow fuses lol.
If I attempted to use solder on a small chip, the whole board would get it!
Impressive electronic knowledge.
I love what you do my friend!
i love this channel n cant wait another video again...., great job dude 👍
Why doesn't this guy have millions of subs?
because millions of people don't have specific technical needs or means to go through a process like that, or prefer different videos from different channels all together that fit their needs
couse when he speak, he lips.. he should back to school learn english couse he want speak more english like native english ppl.
Yea i think this guy have a special potential and genius enough ,maybe some people just like entertaining video content . but for me this video content is so good ..
It's simple, this video doesn't show nothing special. He don't even need the multimeter. He already knew the problem because of the "pc analyzer" pcb. He's just speaking non sense things that people who doesn't understand will think woahh he knows so much things 😁
Not many people have the tools, expertise, or the willingness to repair their motherboard down to the component level. 99% will just throw the motherboard away and buy a new one.
Oh, wait, It seemed to me, or I just heard "Dosvidanya"? O_о Thx for the video! From Russia with love.
You are Tech Rockstar. I have to keep rewatching everything. Ogromnoe sposibo.
I like when you say "We have a picture" :)
so cool man and you are growing as hell I wish my channel grow that fast congratulations my friend
wow I could just watch this guy all day
Hey i repaired similiar board.Asus Z97 Pro with only 1 bent pin :D
Easy repair
jump the power supply = touch green wire to ground and turns on.
@Robbi Robson i only do to turn on psu if i dont have a motherboard to see if it works.
greetings from Indonesia, thank you sir, the knowledge is very useful.
Oh gosh, this is getting much better, now fixing mobos at the component level now
Nice bro I am fan a.c. of u bro ur awesome .
like always, great job man.
Love the work !
Great repair!
We have a picture!!! Love that line :-)
You're amazing ,, nice job
you are a god with tech
Love the videos and I hope to see more motherboard repairs.
brate jesi ti naš? :) svaka čast.ti si genije ;)
Nicely done! I don't get the dislikes... what's wrong with them?
Keep it up 😉
Опаааа :D :) Great video mate! keep up the good work! :)
That reballing machine is one nice thing to have .
great video, like to see more.
I like him when say "we have a picture"
krasava!!! Awesome job
very interesting! rare failure. Most of the times the power delivery to the CPU fails (Mosfets or even the capacitors on older boards)
Probably overclocked and the hub couldn't handle the higher frequency or higher voltage.
Great repair.
Nice video as always
Hi i have the same bga rework station but sometimes i have problems with motherboards of laptops , motherboards layers blow, what temperature you use?
love these videos man by the way where do you order the chip?
Stephen Dean taobao, Ebay, AliExpress
@@elitech3339 I wouldn't trust anything from AliExpress
@@ethanthompson3934 don't worry i Order my Chips from aliexpress because all the chips came from china so why don't by these chips from china. All came to me correctly without a Problem.

Hello excellent video!
I wish you would have shown the points where you were checking for each item. Thanks for the video.
This guy is genius
I'm proud your experienced to troubleshoots a dead motherboard. That's the most underrated and comprehensive boardview of that moboard component part operations video tutorial ever so far. But I need help a quick question my friend about my Asus P4P800-E Deluxe motherboard. This is my first time trying to resurrect/repair my dead motherboard. Only certain part I repaired and changed/replaced already the (1) BIOS chip, (2) capacitors, (1) IC-driver controller to mosfet, and (2) transistor mosfets (negative side body) near side of the CPU processor. I have the PTi9 LCD PCI Diagnostic Analyzer Tester...indicates LED lights of +12V, +5V, +3.3V, and Reset are good (lights on) & fan runs means no problem on transistor Mosfets anymore as I double tested too that 12Volts are running good designed to run CPU processor. But the PTi9 LCD PCI Diagnostic Analyzer tester still telling me that there's signal error, it says check the CPU and power box (power supply is tested good all +12V, -12V, +5V & +3.3V) and the other two indicates that RST and FRAME are both Invalid shows in PTi9 tester. Also I'm seeing LED lights of FRAME, IRDY, and SYSClk are off, it shows in the PTi9 PCI Diagnostic Analyzer tester. I have the "Boardviewer" software (to see the schematic diagram of P4P800-E Deluxe board) that I clicked the CPU drawing part and looked at the RESET, looked at the motherboard then tested the Resistor that is soldered/connected on negative side that the value is correct that has no problem. The two pin reset (for the button reset) doesn't work when I pressed the button. If you have time, please try to look on the Boardview in part of the RESET pin because it's not working. I don't know about that FRAME & RST where to troubleshoot that. I touched the CPU processor it doesn't make any at least build up heat/warm. I tested the CPU processor from my other Asus motherboard, it's running fine. What part of the motherboard should I trouble shoot on that P4P800-E Deluxe? This part I'm lost already. I need help, any idea? Great help would be appreciated so much.
Here's what I did, I plugged one 1GB stick ram, 3V battery button, fan for CPU, plugged-in the PTi9 Post Diagnostic Analyzer Tester, unplugged CPU processor and 12V-4-pins, then plugged the 20-pin power supply, then turn it on, everything runs even though it's unplugged CPU and 12Volts-4-pin. On the tester it shows LED lights on at the +12Volts, +5Volts, 3.3Volts, RST, CLK, except FRAME, IRDY, and SYSClk. So, it means the issue is at the Power Block of CPU because CPU doesn't build up warm/heat. Problem is still don't know where is the one that doesn't provide either the +5Volts or 3Volts or 1.2Volts. Intel 82865PE MCH Chipset build up its own heat but it has its own original heatsink since P4P800-E Deluxe was built in & sold in the market.
I also thin if you can adjust the Camera so we can always see what you are probing would be a great benefit for your channel. Also maybe talk about your thoughts behind the stuff that you are doing. for example: why connect those two things with the Multimeter? Or which multimeter settings are best for the specific task you are doing.
Love what you are doing and you seem to be a nice guy, so i hope this helps you grow a bit more. If that is your intention of course ;)
Hi Eli, do you have a reference for that POST diagnostics board you use? I assume it is always the same - or do you have more that are specific to brand? I would like to repair an old Intel motherboard that doesn't post also.
13:00 we have a picture 😍😍😍💪
awesome brother, subscribed
Amazing I wish I had hour knowledge
Excellent work Eli , keep it up... in 3 weeks i will absolutly slaughter 2 x gtx 970 boards ;)
wow.....u r too good......
great job
I been wanting to do something like this for fun, though I beat on eBay in bids. I think it would be fun to try.
Thanks for sharing bro, what temperature did you use and what exposure time did you take to solder the new chipset?, thanks.
Have you quit making videos I miss them I had just subbed and really enjoyed all of your videos I’m now working on an x99 board and have found your videos to be massively helpful and very interesting please make some more
Hello, do you reprogram the BIOS the Intel ME? i notice when i replace Chipsets i need to reprograme intel ME firmware
como dirían en mi ciudad eres un barbaro!!, mean you are great in your job!
Don't forget to clean ME region in bios after chipset replacement, otherwise the system will act strange in all sort of ways. Anyways, nice job.
and we have picture!!!! I love y man
Hi Eli.
Can you please make a video about the reballing station. Do you have different settings for gpu and mobo? What settings do you have.
And please make videos more often!!
Golden regards...
Hey Eli
Just subbed via patreon - great channel!
How would you fix a broken PCIe connector? The actual plastic shield is ripped off and the legs are broken.
You are truly amazing I want to donate to you, or help you out with some hardware
good job ;)
Genius!!!!!
good job bro ;)
We got a pictureeee , nice
Great work I can only imagine how advanced you are now. Where is a good place to order the Z97chipset from?
What is that machine you used to remove the chip? I know little to nothing about electronics but your vids are really satisfying to watch 👍
It is a bga rework station an IR 6000 station
@Eli Tech can you give me any pointers? I just found your channel and will be watching going forward.
HI! What training do you have or how did you learn?
I have a motherboard that is broken apparently. CPU fans starts spinning and all just shuts off in 2 seconds max. I'd like to learn to diagnose and repair them myself.
Hey man sorry to bother u 2 years after u posted the video, but i have the same motherboard, something strange happened today, i started my PC and i got an instant smell of burning, i turned off the PC immediately, then i opened the PC to see the damage to the Motherboard, to my surprise it was only that small chip that is between those 2 small capacitors beside the sysfan3, so i removed everything from the PC but the CPU + memory, then i restarted the PC and it worked just fine, then put everything back GPU and all, and the PC worked just fine, i could run heavy apps and games no problem, then i used a multimeter to check the voltages on those sysfan3 pins, all was fine, then i turned off the pc and left if to drain all their power, no battery or power for a few hours while i was at work, when i came back i checked the resistance on those sysfan3 pins, all was fine too, so i connected another fan to that sysfan3 and it worked just fine, pwm and all, fan speed worked no problem, the PC works fine but that specific chip between those 2 capacitor close to the sysfan3 its visually destroyed, i can even see the inside of the chip, anyway now im curious about that chip because in my mind it should be impossible for that chip to still be working after literally caching fire and sending sparks... if u want some photos just send me your email or WhatsApp or whatever way u prefer, i am no bot or scammer, i will not bother u i give u my word, if u can spare some time to give me ideias about what that chip does or why the PC "works fine" i would really appreciate.
Old video - but a question - What is that card you plug into motherboard? Thank you for sharing your knowledge.
Hey Eli do you put flux before reflowing new hub (chipset)?
Great work! You really are an expert.
By the way, I have a problem with my PC. It does not turn on even the case LEDs. These are the tests that I've done:
1) I tried to unplug everything except for CPU, RAM, and case fans. It still does not turn on.
2) Then I tried to remove even the CPU and RAM, but I still connected the PSU to the motherboard. And then, I tried to turn it on using the power button through MoBo. This time I got a feedback and all case fans works.
3) Then I tried to plug the CPU again to see if it will not turn on. Yes, as expected, it does not turn on.
What can I conclude here? Is PSU and MoBo still good? Do you think my CPU is faulty? Thank you.
lol diagnostics are not free
yes
Nice
The probe in left hand while measuring resistance, where are you connecting it? Looks to be outside of the card?
hello and congrats for your good jod! a question plz which brand of multimeter you use?i want to buy it
i found it fluke 15b+ :)
what are you putting your multimeter probe on near the io port? Looks like the usb header?
Great video. I have a msi motherboard that the cup fan spins but the motherboard shows no display also the pic e slot has no power. What would be your opinion on what's wrong with it. Thanks
where did you get your preheater / bga rework machine? how much?
What kind of work station is that? it looks amazing!
How did you learn to do this sort of stuff. Is there a class you took on this? Is it fairly easy to learn?
NICE CHANNEL
AV JUST SUBBED TO YOU
Hi Sir, been watching your videos, can you show us the test points including resistance and voltages both GPU and Motherboard? thank you
I'a russian and I watching your channel. "dosvidaniya", "opppa" - in the past do you live in Russia ? ))) cool video, man. Your solder is G90 ? you must try solder T12 - they are the best
Eli Tech, can you tell how to fix SATA3 ports , or what to look for when trying to diagnose it?
What is the model (and brand) of the tester board wich u put in the PCI slot? Thank You!
wait for this dude to get flooded with Asus motherboards especially x79.
Oh, no: why? Are they all really faulty? I have one and It's been freezing randomly while gaming. I noticed that exactly above the chipset it gets really hot.
Lulz I actually was looking for a way to get mine alive again since it's laying around for 2 years not working 😂😂
@Eli Tech, i have asus rog rampage vi apex mobo and few pins in socket are bent and tried unbending them and it worked fine, later on i had a leak in waterloop and A1 memory slot stopped working and i sent it in repair to asus but they declined to repair under warranty due to socket pin damage even though even though it was not a problem, later i tried to mess with pins again and broke one ( like 6-7 pins were bent and i broke one trying to bend them back again, so i purchased a new 2066 socket and i should get it soon, will u be able to replace socket and also check why A1 ram slot does not work, at this point i dont know what else is not working as i have not used it ( but after the leak i dried it good and it booted fine except for A1 ram slot not detecting any ram), do u have time to fix my mobo, thank you.
