Thank you @CareyHolzman for sending me these mini PCs to work on!
Hello there and welcome to my video. In today’s video, I’ve got two broken mini PCs that were sent to me by fellow…

I might have accidentally said that the system was powered on when the RAM was changed during the live audio portion of the video – if I did, I meant to say that it was plugged in. The system was not powered on. My bad there!
Looks like memory controller in cpu is same for igpu and it may be dead)
Sounds like the CPU's memory controller got zapped during the RAM swap with power on. Probably no easy fix without replacing the CPU. Tough break!
Try to reflash the bios, a corrupted bios likes to cause the Ec chip not to power up all rails. you can reflash the bios with a cheap EEPROM Flash BIOS USB Programmer, some even have clips so no need to solder. You said Carrie had it powered on while swapping ram? that sounds like a very good reason for the bios to be very corrupted..
Some integrated graphics use ram as of vram so thats probably how it broke

29:00 posible this driver for graphics need "enable signal" or-and "ok signal" pls see datasheet if plesent on internet. This same thing for KBC and bios power
29:00 Easy, drop scudriver or any other metal relatet part or/ I dont now about this board architecture but posible when ram is changed its pin ben shortcuted
Try reflashing bios
It looks like the first machine has 2 dimm slots, just stacked. Not sure if that's true.
Ah ok merci beaucoup 😊et
try turning it off and on
“Now it’s gone forever?
For the BeeLink – Recently replaced SODIMM RAM on a laptop (HP). Power is never really “disconnected” and I had no issues. I know there are “power off” options in some laptop BIOS to, as best as possible, remove power but didn’t see one.
From other comments from people with boards from the same company, could it be a flaw that they treated power as a desktop instead of a laptop, so that, with plugged in power, that left power on that fried the channel? I definitely think you’re on the right track. Also seems others had issues replacing boards other than RAM, so could just be a manufacturer issue too.
Thanks for the great troubleshooting process!
Hmm this video make me thinking twice before buying Mini PC, the space not the problem but I like compact system like Mini PC and AIO PC, but most of them expensive and have performance issue even when compare to cheap PC build with cheap GPU like GT 1030.
Its quite possible the PCH died the CPU getting very warm is kften a sign of a dead PCH seen this itten in laptop repairs
Often enough i find using a thermal canera can confirm a dead PCH as usually a corner of the CPU gets hot and the system is fit fir the bin
But also this could be a sign of a corrupt bios have came across this issue before and taking out the bios and reflashing it can bring it back to life
Those are the 2 most common problems i have came across when doing laptops
This video is 😂 funny, in a good way. When the resistor flew away and when he ripped the pads for the resistor. I hope you keep making videos and learning computer repairs. Also they sell very cheap memory tester to test open and shorts from memory to CPU
Is there oxidization or metal eaten away on the RAM connector pins? RAM unplugging and replugging while the system is on could make some pretty little sparks.
Deoxit and if that doesn't work, soldering in a new RAM slot might be an interesting thing to try. Also, something to consider, if there were pretty sparks created, then maybe it could be physical slot damage due to human jumping.
If it were plugged in and the ram was changed without draining the power first, integrated graphics uses your system ram< 31:00 (shared) I can understand how that would effect the other.
15:51 … "In short" ⚡🤣
I bought a Beelink Mini PC. All was well, until it refused to work with a brand new SSD mounted in a USB enclosure. At first I suspected the SSD, but my Beelink's USB ports are very flaky, and connected drives malfunction. Beelink were no help at all!
Amazon gave me a full refund, and let me keep the Beelink. I then bought a Minisforum, which unlike the Beelink, works perfectly with all my USB drives!
I like Mini PCs due to their tiny form factor, and their highly efficient energy usage, compared to my old home built desktop! Also, this allowed me to upgrade to Windows 11, love it or hate it, for very little money!
You should plug in a network cable and see if it lights up. It might be booting with no video.
Wow! Superb job! I did not understand much of what you said towards the end of the video, but it was fun to watch either way!
try desoldering the bios , flash it outside of system .
Try this: Connect a keyboard directly to the machine (no kvm switch). And when you turn it on try to press del, esc, f7, enter or other keys. The f7 is the one for entering bios in normal situation.
In similar situation, After some trying, I noticed the keyboard started showing life and display also turned on
Some of these mini pcs have bad bios and they does not turn display on boot screen even if they "show" a message and waiting for input to continue.
Wouldn't the voltages to VCore be limited or off as well as the Display core/Memory side of things?
I would work backwards from PQ8 to see WHY there is no voltage output, in short are all the
enable pins of all Chips activated and why one enable is not being enabled..
