Red herrings, red herrings everywhere (4th Gen Intel Build, No POST) - LFC

[@Adamant_IT]

Brief FAQ because this video's doing numbers: Q: You didn't test the other RAM slots. A: Yea that was a cock-up, dead slots are actually very uncommon, but I should checked another slot when I dropped down to a single module. I think the fact that I was getting absolutely no response from changing the RAM config was why I moved away from that, if there'd been _any_ change of behaviour (power cycling, etc) I'd have been more thorough. Q: You should've known it was memory issues, you should've looked up the POST Code right away. A: I think you missed the part where it was nothing to do with memory, and the entire message of the video is to watch out for misleading symptoms. Q: This board has BIOS flashback. You didn't need a programmer. A: This was my bad - despite talking about flashback in the video, I didn't actually check. But hey, it was still a chance to show of other techniques that exist. Q: It's dirty! A: Yes. This is pretty normal for most PCs. Very few people clean their PCs. It usually won't stop anything from working, unless a fan is completely blocked. I inspect before cleaning because if something breaks during the cleaning process, I'll know it was me, and not a fault the PC came in with.

[@animalm4st3r]

Dead Memory slot is highly unlikely cause atleast since 4th gen and for AMD with Ryzen the memory controller is inside the CPU so unless you have a physically damaged slot memory issues come from the CPU

[@sobolanul96]

@@animalm4st3r Had that issue on an AMD processor. I thought the motherboard had a burned out channel. It turned out that the processor was faulty. When it is a processor issue two slots will fail at once, while a motherboard issue will usually give you one unusable slot.

[@mrtuk4282]

How much did you charge for the total repair ? Was the charge a fixed charge or dependant on CMOS Battery, BIOS flash, etc ?

[@diaman_d]

carbide 300R . did not try the other memory slots, it works just the same even if the mobo suggests to do otherwise. Still not a rossman you...keep learning. You jumped hoops , the bios flashback was good next step. The empty battery makes the dead/corrupted bios very much possible. Asus has the bios flashback function , bios onto a usb stick , much easier. You wanna learn about bios and cap files , check fernando's win-raid webforums. plenty more to learn there about all things bios, management engines, microcodes... About bios flashback, it can be picky about the usb memstick used. I myself have such a case with a p8z77-m i7-3770 fully updated customized bios... had to do it myself since Asus dropped all support . And it's still running strong, though i just upgraded to a i7-11700k system.

I like that you actually fixed it by reflashing the bios instead of just replacing the motherboard as so many other "tech" or "repair" channels would have done. A ch314a with a clamp is only like $15 after all.

[@GadgetUK164]

Great job! The benefit of ignoring the obvious (the error code) - you covered lots of other important stuff that was worth investigating regardless of the fault. eg. Say a BIOS reset (via that button) had fixed the problem, you wouldnt have seen the dirt in the memory socket, nor the unseated heatsink, and the connector issues. My view with any fault is rule out all the low hanging fruit (as you described it) first, regardless of how obvious the POST code might be - you will be surprised at what you discover and the end result will be a far more reliable machine. My other "goto" there would be to measure voltages and perhaps scope them.

CPU needs no cooling, so bizarre, it lived years "semi-cooled" and survived! to tell us about it, amazing

[@GGigabiteM]

Intel has had remarkable thermal throttle protection since the late Pentium 3, something AMD didn't do until the Athlon 64 era. I remember many a Athlon/Duron/Sempron suffering basically instant thermal death if the heatsink wasn't installed properly. If you left the CPU without a heatsink, it'd quickly shoot up to 700F or so and either burn or explode. I still remember a kid back in High School turning on his personal Athlon build without a heatsink and unfortunately for him, the CPU detonated and sent pieces of itself flying up into the ceiling. Thankfully the case was on its side and contained any shrapnel from hitting other people in the room, but there were gold pins and bits of ceramic embedded in the ceiling for the rest of the year.

[@bestage9429]

@@GGigabiteM Reminds me of that old Tom's Hardware video where they did a heatsink removal test on a Pentium 4, Pentium 3, then two Athlons while running a game. I once came across a video on KZbin where someone pulled the heatsink off a Duron while it was running, and the chip literally flew out of the socket off the motherboard, a few seconds later. Many people in the comments thought it was bullshit, maybe it was rigged with dynamite under the CPU or something, I too thought this was unbelievable and had to be fake. But now after hearing your buddy's experience I really wonder what can cause these CPUs to explode if heated up to extreme temps rapidly. Whether one of the materials the package is made of has violent explosive properties at high temperatures (like TNT), or there's a pocket of air or something inside the CPU can cause it to explode like that.

[@GGigabiteM]

@@bestage9429 >I really wonder what can cause these CPUs to explode if heated up to extreme temps rapidly. Really no need to wonder if you look into thermodynamics of materials. Bridges have expansion joints so they don't blow themselves apart. Tiny temperature changes can cause thousands of tons of force. This is the same thing that causes BGA failure on ICs with ROHS solder, the thermal cycling causes movement in a material with no ductility, so it cracks and fails. In early Socket 462 Athlons, the package was a hard ceramic. If the core rapidly heated to 700F and the surrounding ceramic substrate didn't follow, it could create enough force to blow the package apart. I'd imagine it'd be much more likely to happen on a new chip rather than an old chip, since the ceramic package probably had micro fractures in it from thousands of heat cycles that could allow some give to expansion. In all three scenarios, you're dealing with hundreds or thousands of pounds of force. It'd be like putting a ceramic block in a hydraulic press and having a pikachu face when it exploded from the pressure.

[@1pcfred]

My i5-4670 CPU runs cooler than a cucumber. I only have a Hyper T2 fan on it too. Was a whopping $10 when I bought it. Does the job though. It is a bit cool in the shop today but the hottest core temp is +24.0°C One core is +19.0°C It's really chilling.

For the average daily user it wont show up as a failure. The CPU will simply throttle down and run on a much slower clock speed, thus producing much less heat. It will most likely appear as a random slow reacting PC during the active session.

We don't know how much of it happened after the PC was experiencing problems. Typically someone will try to fix something themselves before seeking expert help.

Very good video well done for proceeding to find the fault and then the way you cleaned it all up and put it back 👍🇨🇻

There is a litte trick for getting rid of code 26 on Asus boards. Remove all Ram modules and power up the computer. Wait 10 seconds and power off the system. Do this one more time and then plug back the modules. Works like a charm.

Man, I’ve never subbed to someone so fast. You had me at no 8 pin connected to MB 😂😂😂 we’ve all been there brother!

Great video the dust and bad cable management was messing with my ocd 🙂

[@JeredtheShy]

Ultimately the thing that's satisfying about this, as a potential repair customer, is that combination of not needing new parts but also the fix required some professional equipment and knowledge I wouldn't have had, so the repair fee would still feel like a good investment, anyway. Finding out a cable just needed pushed down a bit would have killed me.

Another great video, loved your frustration, "I'm Tired", well done.

[@dandel351]

Great video. Always good to learn that those post code readouts are not a be all end all solution to a problem. I wonder how many MB's end up as E-waste due to these bios chip failures.

[@alanhowson2270]

Brilliant. Your depth of knowledge is really outstanding.

My first pc build was with a 3570k, had the stock cooler for a week until my CoolerMaster 212 evo showed up. Even with my R5 3600 only had a stock cooler for about a week. Got yourself a new subscriber.

The customer will be doubt be enjoying a fast and more responsive computer, now that the CPU is cooled properly. Good work. I have the same programmer (it has paid for itself as it has recovered 15 motherboards).

[@antoniobaric5798]

Incredibly informative and fluently presented. Thank you!

[@raekan2006]

[@sheek1982]

Absolutely love Windows desktop repair videos! 🙂

[@saberking7869]

He did use Windows to fix it, but the process would be identical regardless of his OS. A Windows desktop problem could be a missing recycle bin or something (one of the students in my school had his account with taskbar jammed at top of screen, this is a Windows desktop problem)

[@metrotechguru5863]

Brilliant. I'm so glad your back. I've missed you terribly. Happy New Year.

[@danw1955]

Very intuitive problem chasing! I've never had to do an actual BIOS reflash out of the motherboard, but I probably could have saved a few if I had! I love the attention to detail and cable routing when finishing up. I'm also a stickler for that type of thing because it makes it so much easier to work on in the future, not to mention, looks a lot more professional!😉

[@PaulLemars01]

Thank you so much.This was a really enjoyable video to watch. Just subscribed because this is ASMR for hardware geeks.

[@mrpetit2]

Nice repair. Best wishes from the Netherlands🍾

[@cosminmilitaru9920]

I got an adjustable leaf-blower so that I can dust-off these PC cases before working on them. Because that much dust bothers me from focusing on other things to do, and I've used so many canned compressed-air sprays... Thank you very much for the good and informative video! :D
