@@R2_D3 Heat actually is! Usually as a result of dust. Electronics hate em'. "THIS ONE TRICK THAT COMPUTER COMPANIES DONT WANT YOU TO KNOW...BUT THEY CANT STOP YOU!"
I used to fix computers in the -00's and absolutely loved the debugging and troubleshooting. These days I prefer just watching professionals at their job and get a kick out of trying to guess what's wrong before you solve the issue. I really enjoy these videos, thank you!
Hey me too from 2003-2007.....more of a hobbyist now...i watch these tech vids to refresh and keep up with the current hardware.......you could have knocked me over with a feather the first time i saw an M.2 SSD.....just wow.....going from a brick of a drive to one thats the size of a stick of gum?.....love this stuff Side Note: that was also the last time i saw a Fatality board ........around 2006, roughly
Thank you for the programmer recommendation. 👍 BTW, 5:22 this assumption made an ass out of me *once* . A motherboard refused to forget its settings no matter how long I kept that jumper in the shorted position. CMOS reset worked only when I removed the battery, turned it sideways and used it to short the 2 pins for 5-10 seconds. Also, *very* important - when you turn off a PC (or any device) to do hardware manipulations, *always* hold the case power button pressed in and even pump it a couple of times to completely discharge all residual electricity from the caps. This is why even when you just turned the PC off and unplugged the power cable when you go to press the button, fans will still try to spin and the MB's power indication LED is still glowing. 😉
Second time I've watched this one, but the first time I stayed on to the final comments about the phase activity LEDs. Love your enthusiasm and energy 😀
Interesting one, great that you were persistent enough to actually find the issue and solve it properly, i'm sure a good number of b&M repair shops would have just called it a day and said the motherboard needs replacing.
I just found your channel and have been really enjoying your videos. I like hearing your troubleshooting explained in detail speaking to even beginner levels like me. So many channels expect viewers to be at their knowledge level. Thanks for bringing us along with you
this is why motherboards need two bioses, love this bios setup it was always a life saver. I to have fixed by flashing chips with the 341 programmer, i think it was called that. TechYesCity did one about Bit ROT where he fixed a mobo by simply reflashing the chip with a new copy. Anyways great videos, big fan
Incase you didn't notice, when you rebooted into UEFI-A, 38:04 there is an option to flash the A -> B like there was before to B -> A incase you really did want to update both, with out having to use your USB drive. Theoretically this should also back up any customized user settings (XMP, overclocks, etc) in UEFI setup to the other EUFI chip.
well I saw a PC that was thrown out, and when I checked what CPU was in it, I was very happy because it was a 2600K. This was some years ago now. Unfortunately I soon learned that the reason the system was thrown out, was because it had a dead CPU... presumably too much voltage for too long, or someone accidentally gave it way too much at once. basically, I'd argue it can be the CPU, but only if it's a K series :D
Over my 25 years, working on, building, repairing computers a have seen a few (only a few) dead CPUs. It can happen. I have learnt to follow my instincts but also never rule anything out (cables, foreign object (paper clip, screws, etc). Also good to get the motherboard out of the enclosure / case to get a good look at the board and the mounts (within the case).
Quick tip: If your MB doesn't have a 'clear cmos' button, short the battery connector when you remove the battery for reset. It'll do that when you touch the positive to negative on the battery holder/connector.
Too close to home, oh brother in repairs - I have an older Fatal1ty MB with a Gen 2 CPU. My last boot failure turned out to be a bad optical drive. That old system still does my favourite games with no mouse lag and makes me smile a lot. Glad you're looking good and good health to you.
man, just discover your channel and love it! troubleshooting step by step the way you do, explain so good different possibilities and specific things about electronics, chips, etc. Thanks
Tip for you from 16 years of working with Beep Speakers: Eff em! Get a cheap LED (3v White Strawhat is best IMO) and solder it to a standard connector and put it in the place of the speaker! You can just watch the LED pulse then and it'll show you visually rather than audibly, and that makes diagnosing easier.
The DDR3 DIMM should be on slot A1 and A2, not B1 and B2 like wee see in the bios. But no problemo, for the french man i am, your english is crystal clear and your channel interesting for somebody like me who's working for 32 year in IT and electronic and who's going to leave sooner is job to make the same job as you.
Back in pentium 3 age I made a Bios hot switch between a dead mother board and another live... because flash process fails and brick my board in a first place. I booted the OK, with PSU ON, boot DOS 6.22, then I changed chip memory, and run a bios update IN DOS. It ran like a charm... :)
NICE! 👍 You remind me of when I added a DDR2 stick to the MB *live* once - an incredibly stupid mistake by distracted me. Surprisingly, the PC didn't even froze. 👀 Out of curiosity, I tried to turned it off from Windows and it worked. Followed by disconnecting the power cable, pumping the power button and then reseating both sticks just in case. Turned on just fine, worked fine and held stability and memory tests like a boss. I can't believe my luck and I wouldn't even believe this story if I didn't live it! Got so scared back then - trust me, I *did not* repeat that mistake ever since! 🤣
good video. a corrupted bios can do alot of funky stuff. you got the good luck of the draw that that particular mommyboard had two bios chips and at least one bios was working. i know some manuals dont recommend updating bios but the motherboard manufacturers recommend you update the bios to at least a non beta as there are updates that the manufacturer have implemented to fix small bugs theyve found. if not for the backup bios that wasnt corrupted and bios chips that had been soldered into place the board replacement would have been required. people, update your stinking bios and also keep your pcs airdusted and replace your darn cmos battery every now and then, as their charge cycles are finite and can eventually wear down to no use
Great video again. I really enjoy watching the videos you make about fixing and building pc's. I also learn from your videos so I can improve my own pc building and fixing skills. Thank you sir
You wouldn't believe what I've seen. This one time doing a favor for a mate cleaning out his PC I slid off the cover. What I found inside was the thing of nightmares which still haunts my dreams. There was a dust ball the size of a large house cat laying in the bottom of the case in front of the PSU. I hauled that out and spotted the CPU cooler which had little trails that the pet dander had left in the dust caked beneith the fan. The graphics cards heatsink wasn't any better. The power supply was chock full of dust too. I honestly can't say how it managed to survive being blocked up like that but I got it all cleaned up like new. There was dust and hair in every nook and cranny of that machine though. We had to chuck the optical drive in the bin. There was no way to clean the optical path without buggering it up.
I remember the days when you had 2 bios chips, an odd and even bios chips and even the keyboard had its own separate bios - back then the beep codes actually meant something specific other than memory - a good start is to pull every single card and cable out that isnt absolutely needed to boot - I have seen bent pins on ps2 and usb ports and even on one occasion a duff MS optical mouse prevent a system booting and cause it to sit there beeping on an opti chipset board - BIOS beep codes are specific to the brand of Bios can be specific to the board, in days of old you would get a schematic and list of beep codes at the back of the manual to point you in the right direction - back then there were IRQ and DMA jumpers to set too...
Hi, I have encountered, even if rarely, situations like yours, and the malfunction is difficult to identify. I always replaced the CMOS battery every time for safety, even if the motherboard was of recent construction. congratulations for the video. Ciao, mi sono capitate, anche se raramente, situazioni come la tua, e il malfunzionamento e di difficile individuazione. Tutte le volte ho sempre sostituito la Batteria CMOS per sicurezza, anche se la piastra madre era di recente costruzione. complimenti per il video.
I understand this video is a few years old, however, it’s still an extremely important role even in today’s day and age of 2024 where the same troubleshooting procedures are still being implemented just like this. And yes, in the beginning, you checked the bios, but those three beeps were pointing towards a possibility that there may be some thing going on with the ram and what was really confusing was the three beeps and then when you tried something else, the two beeps and when you conclusion lead you back to the motherboard after testing All of the onboard components on another system you looked at the bios even deeper, and it turned out that the main bios was corrupted, and we also have to bear in mind that the bio program for that motherboard was actually able to flash the bios from the back up to the main And you were able to check that the main bios worked after copying it from the back up and then updating the main bios, however, could there be a possibility that some boards or manufacturers the ref flashing of the back up bios might not take in which case you have to program it and you have to know how to do this like you do not everybody out there can decide or a chip or even pop out a chip and purchase a programmer and successfully program because they are not tech savy, in which case that is where you come in to offer customers your services for a fee. Thank you for sharing your knowledge with us we truly appreciate it.😊
at first i thought it was the molex on board missing power.. i learned something today.. backup B-A feature. win-raid has a good Intel ME section in forums.. i would update backup bios to 1.xx newer at least. some manufacturers usually give at least an SPi header if not socketed.
It might need, reapplying some Arctic Heat Sink Compond, and some dust cleaning. My computer nothing, disassembled some parts, did the vacuum cleaner mode, manually cleaned everything, fan and etc. And it started right up and more quietly.
Dust plus high humidity can cause issues I have found. Semi shorts can corrupt the cmos. I had one computer come in for repair once that had 5 years of dust mixed with cigarette smoke. Everything was sticky, yellow/orange/brown and absolutly disgusting. If i recall I just washed the board down with starting fluid. I was able to get it going again but it was worn out and very outdated.
Intel ME is the management engine that runs with "Greater than God" access and supervises the memory access by the CPU. If the ME firmware gets altered by malware, it is effectively a Rootkit that cannot be removed.
im really starting to enjoy , watching .. a real stumpper .. l.o.l .. i hav a similar problem w/no post .. i too hav probably watched numerous vids on particular problem .. most as u saw , almost all say something diffrent .. but i hav seen a couple intriguing .. well carry on .. i may put mine aside befor i do something I'll regret later .. l.o.l ..
Intel ME is... rubbish 💩 it’s supposed to be an “out of band” platform, just like iLO or DRAC on servers, but this only applies to machines with vPro CPUs and AMT technology, workstations and professional laptops. It works as the TPM module for some laptops too, as part of intel PTT. The problem is that ME is part of every single Intel machine since 2008, no matter of what modules (AMT, PTT, secure boot) are present. ME is active as long as the power cable is inserted, has access to memory (the cpu doesn’t even notice) and it has full access to the network stack.
So true, and if ME gets corrupted then your ethernet connection might be screwed. Or computer might behave weird. There are tools to dump old ME and fix it and load back, but it is tedious process.
@@DJ-Daz It is being continuously patched. More and more exploits are found, it is just best target for exploits. Your firewall, os or antivirus won’t be able to see anything.
Never the cpu is what I used to believe too until I found a cpu that a child had looked at removed stuck to the heatsink and reinstalled without lifting the tension arm. The crushed pins looked as painful as you imagine 😂
One thing that you did not do is to check the CMOS battery. They can go dead or bad sometimes. In this case it was not the problem but sometimes it is.
ME is the management platform done by Intel, which has some features which are useful for corporate desktops or servers (like iLO, anti-theft, etc.) but which are pretty much useless for consumer desktops. People are squicky about it because it can (in theory) use the Ethernet interface to "phone home" even when the system is off, because the ME chip is powered off the +5sb.
BIOS Selection Jumper (BIOS_SEL1) (see p.6, No. 24) his motherboard has two BIOS onboard, a main BIOS (BIOS_A) and a backup BIOS (BIOS_B), which enhances protection for the safety and stability of your system. Normally, the system works on the main BIOS. However, if the main BIOS is corrupted or damaged, please use a jumper cap to short pin2 and pin3, then the backup BIOS will take over on the next system boot. Ater that, use “Secure Backup UEFI“ in BIOS setup utility to copy the BIOS ile to the main BIOS to ensure normal system operation. For the sake of system safety, users cannot update the backup BIOS manually. Users may refer to the BIOS LED (BIOS_A_ LED or BIOS_B_LED) to identify which BIOS is activated currently.
This is why we charge the premiums we do as repair technicians. Sometimes even with a well thought out diagnostic process, one tiny thing will have you circling around for far too long lol.
Please keep in mind Adam, that resetting a BIOS, or any other type of initial memory in any device, can force this device to enter a loop mode. In this mode, might act abnormally. So, this might be the reason, why your last attempt before the post was still no post and, that's why, I do wait longer with all electronic devices after this reset.
I forget to mention it in the videos, however I do usually wait quite a while on boot attempts, but cut the video. Otherwise there'd be like, 15mins more of just dead space. Memory training has a distinctive pattern as well, you can tell when the board is training vs when it's not going to POST.
Your methods are fine, basically what I'd have done, check all cables and reset bios then it's the elimination game, I did with my MB left the backup Bios as is that way I know it works
Yea this is correct, I've never actually spotted which chip is holding parameters, but as it's all part of "the bios chip circuit" I generally treat it as a single thing. At some point I want to make a video that talks about this in greater detail though 👌
@Adamant IT, The short explanation is: Intel ME means Intel Management Engine. It is intended as low level remote management utility for enterprises and businesses. It does not need an OS running, to manage general access to a computer, on UEFI/Bios level for managing time, date, power profile, noise profile.... ETC.... by Enterprise IT teams to enterprise employee computers in their endless to provide a reasonable balance between performance and power savings on one side and reasonable balance between security and usability on the other side. It is Greatly misunderstood by people as a way to control your computer and spy on you. In order to work, this management utility needs Layer 2 access between the managed computer and the managing computers and works only on both computers are within the same vlan.
