Once they pop they don't wanna stop 🤣🤣🤣🤣🤣
lol never thought someone would put a sticker in place of thermal paste, I bet it was running nice and cool
5:40 You can see how the first caps vents in the video here, bottom left first and then between the ram slots on the right, the caps have lost their oxide forming layer because of long time no use, and they likely was a cheap type to begin with and since you have no way of raising the voltage slowly they just go pop instead
Thank you of your video, this was very interesting to see how the caps just exploded, good that you got that motherboard working.
Richard you are the Best.
13:20 Bleep & Poooop 🤣🤣🤣🤣🤣
The AGP card is a 5900XT, not a 4200Ti. Nice score!
love this vids, never know what will turn up on these type of vids
Plextor drives used to be the Ferraris of optical drives but they were bought up by some other company, and they have cheapened the quality of most of their remaining products. You can buy a Plextor optical burner for $25 just about anywhere now.
Plextor factoid: in the early days of burners, the quality of optical media was total shite, so Plextor used to encode specific brands of optical media into their firmware, hence certifying those products. They were generally premium brands, or the top lines of medicore ones
Plextors were the standard by which all others were judged though, and few held a candle to them.
Super stuff
ROFL ... Love videos with Pyrotechnics...
The more explosions the better... 🧐
excellent video
Love your humor Richard - wide belly TV lolol
It would be awesome, if there was someway to mount your thermal camera above the bench top(capture from edge to edge of a motherboard for example). Then come up with some code that compares one frame of imaging to the last, then it could display almost real time imaging that what point out potential problems. It seems with the size of thermal imaging displays being so small, that one side of the board could catch fire and the person looking at the display wouldn’t know until they smelled smoke. Thanks, as always, for the videos. They are super helpful.
Heya, nice the spaks are vlying around this video something differant for sure. well this video didn't end up in negetive numders and 1 more nice carboot sale unpacking/opening party
The 4xxx TI cards are collectible and highly sought after for retro gaming. I would try to repair that 4200 TI if you can. That would be a great video to do!
Exploding capacitors aside (that's the crux with very-low-ESR types, they can be quite prone to high leakage in old age), who leaves a _bloody sticker_ (Podcastage voice) on the processor? I'd be willing to bet it shipped liked that back in the day - top-notch assembly job right there...
That Asrock H61 ITX board with your spare i5-3450 should be perfect for what you want, assuming you still have two 4 gig DDR3-1333/1600 modules floating around (I mean, 4 gigs total will generally do with an SSD but is getting a bit tight these days). Should be almost as fast as the 3570S I put into into my office rig not too long ago, replacing an i3-2120. It was about time I did, modern browsers were starting to act up with the now rather old HD Graphics 2000 driver, and the performance boost was obviously welcome as well.
Good score on the P4 machine. I notice the heatsink on the TI4200 looks rather plugged-up, so if it ran for that long enough the fan bearings / lubrication and the capacitors around may be a little worse for wear even if the silicon made it. Blowing upwards is about the worst position for any sleeve bearing fan, that's why these old graphics card fans tend to keep dying. With some luck a fan refurb, cleaning and the odd new capacitor will revive that one.
The ASrock H61 board is running sweet with Windows 10 in the small AMD case now, I fitted the i5-3450, 2x 4GB DDR3 1600 (because I don't have any 8Gb dimms to hand) and a 1TB SSD. All used parts. It's slightly larger than ITX form factor but it fits nice.
The D865 Perl is a great board. These are not cheap in the US to get hold of
I'm working on another P4 Titan series motherboard (a SiS-based one) and I've had to replace all 16 capacitors like those on this video. They all had capacitances twice or 3 times its rated value. What a coincidence!
it looks like you were not plugging in the 12v atx cpu / eps power socket on the mobo, could be why you were popping caps?
I noticed you're now getting the "T" ads (not ^itty although that's what they show for attention) they're everywhere.... and I have a question. I bought an external DVD (which worked with the usb power cable provided) and then I forgot about that cable and plugged it into a 12V supply - bad move! should have been 5V now what do you think might be blown in it? The components inside are friggin micro caps and resistors etc. as well as some poly carbonate caps. I had this same issue before (pity I didn't recall) with an old 2005 IBM Rewriter, but when that is plugged into 5V now it opens the tray and the new one doesn't. Neither work. BTW the "new" external is a new casing with a 2006 burner in it, trust me I wasn't expecting it to be THAT old from the "T" company..... go figure! 🙄
Exploding capacitors not so much fun when they are the solid state polymer type. I always wear safety goggles now when testing. I had replaced a short mosfet, felt the psu fan blowing on my arm moved my head to look and the capacitor blew up like a 22 blank. I never found the aluminium can.
Had one of those cheap buck converters blow up in my hands once. (Reversed the voltage, I think) I did find the capacitor can, it had a nice dent on top where it hit my fingernail.
As a kid I'd occasionally stick them in the end of a tube and put 240v across them.
That was true mine field
Nothing better than a exploding computer for entertainment. I enjoy your vid, especially when you take the camera to the Carboot sale.
Hey Richard, the gigabyte board sure was a banger!! HA! HA!
12:06 can the analogue multimeter detect this fault?
And THAT's why you replace ALL the capcitors.
Would be interested to see what you can do to troubleshoot the graphics card.
Yeah I'll take a look at that
Well, i knew it was going to be an onboard rage. With the p4 era of cards it's just crapshoot really, so the first board i was way off.
u have a 3.2 P4 as well - worth $40 on its own
Love me some car booty time haha ❤
From now on all Motherboards should have exploding capacitors!! haha
The reason you're not getting any output on the first PCI slot is that it probably shares the IRQ with the AGP slot.
Why does it stop the motherboard from booting up?
@@LearnElectronicsRepair An IRQ conflict most likely occurs when two pieces of hardware are attempting to use the same channel for an interrupt request. Since the Programmable Interrupt Controller (PIC) doesn't support this, the computer might freeze up or the devices will stop working as expected (or stop working entirely).
@@andrewsz8552 I understand the concept of IRQ conflicts but in this case there is nothing in the AGP slot and the motherboard does not have onboard VGA nor is there any other card inserted apart from my POST analyzer so what causes the PC to hang with my analyzer in the first PCI slot?
@@LearnElectronicsRepair Ok I just took a look at the manual for the d865perl motherboard and it appears @PeetHobby is correct about it being something to do with pci interrupts but it's not a conflict with the agp slot but rather it is most likely a conflict with another onboard device (audio, lan, PATA). Each of the slots handles a particular type of card differently. Cards can be type INTA, INTB, INTC, INTD depending on the number of interrupts they need, i.e. all cards that need only 1 interrupt are classed as INTA, ones that need 2 as INTB, ones that need 3 as INTC, INTD. In this case the ICH5 chipset internally assigns it's 8 programmable interrupts PIRQA, PIRQB, PIRQC, PIRQD, PIRQE, PIRQF, PIRQH, PIRQH differently to each type of card in each of the 5 pci slots, so in the first slot, a type INTD is assigned PIRQE, a type INTA card gets assigned PIRQF, a type INTB card gets PIRQG and a type INTC gets assigned a PIRQH. In the subsequent slots, however, the assignment is different:
This means that if you had a card of type INTc, the ICH5 chip would assign it PIRQH in the first slot, PIRQE in the 2nd, PIRQD in the 3rd, PIRQF in the 4th and PIRQA in the 5th slot.
If your interested, pages 54-58 make an interesting read of the manual on the manualsbrain website:
manualsbrain(dot)com/en/manuals/6334/?page=54
@@LearnElectronicsRepair The system keeps reserving resources even for the empty AGP slot. In this case it is not able to share the same interrupt request line with your "special" post analyzer and freezes immediately. The post analyzer is a special device that needs an unshared IRQ on this motherboard (chipset).
I dare you to give one of these popping boards to Julie, lol, just to see what she thinks. What brand were those caps? Surprised that the popping didn't take out any other parts. Also are low esr capacitors not any good then?
Usually when electrolytic capacitors fail, they go low in value (50% less uF than rated or worse) and high in ESR (several ohms or more). But just occasionally they fail by going high in value (usually around double the rated uF) very low in ESR and high DC leakage current. That is what was wrong with these ones and why they kept exploding. The best indication is the abnormally high uF reading, you will not spot them with an ESR meter alone. The best answer is to always measure the ESR and uF, and be very suspicious of any that read much higher capacitance than they should.
@@LearnElectronicsRepair Thanks Richard, much appreciated
38:58: If I remember correctly, Win9X and Me didn't actually have user separation. The login was only used to load a specific user profile and to set the network credentials. You can just skip the logon dialogue by pressing "Cancel", and it should go straight into the default user setting. Microsoft-grade security.
A decent analog meter is good to look at a capacitor charge ans discharge.
“Exploding it is caps”? Who wrote the title of the video?
Me. Surely that is the correct english grammar, Exploding It's Caps, as the apostrophe represents the fact the capacitors belong to the motherboard. But google says I am wrong so what do I know?
Let's be honest you can't trust Google to come up with the correct English grammar, as it's an American derivative 😂. I'm fairly sure that my sentence is grammatically incorrect 😊.
@@leviathanmac3053 Well apparently google tells me that for example as I run this YT channel, I can type 'This is Richard's channel' and the apostrophe designates my ownership of the channel, where as 'This is Richards channel' would designate that there is more than one Richard (plural). But if my name ended with a letter S, I would have to put 'This is Marcus' channel' as Marcus's channel is incorrect grammar. This is what they taught me at school when I learned to write. So exploding it's capacitors should be correct but apparently it isn't because with the pronoun it, the rule is the opposite way round. Probably they taught me that at school as well but either I forgot or someone changed the rules and didn't tell me. I have no idea how they teach kids to write it these days. I should have put the title in Spanish, the language is far more sensible in this respect.
@@LearnElectronicsRepair Lol. This thread quickly turned into LER - Learn English Repair
@@LearnElectronicsRepair Hi Richard, to be perfectly honest, my grasp of English grammar is not great, not a great one for study at school, however I was fairly certain I had grasped the meaning of the title. I tune in to learn and understand more about electronics, not to gain a greater understanding of the English language. I am an engineer to trade, mostly Horticultural/Agricultural and Groundcare machinery, but I do have an interest in the SBC area for fun, I am gaining valuable knowledge through a great channel. I like the channel and the banter, so carry on regardless :)
