Re: Why did my motherboard catch fire? Also, what can be saved?
Looks like it's limited to the USB power, the rest of the board should still work.

A mobo does not have any voltages that could arc over. Agreed with the above, it looks like a short on the USB header.Leave a comment:

I can't understand how this unit never shut downbefore it got this bad the protection circuit did not do it's job why? Was anything changed from the manufacturers spec's ?
I would not be useing any board from the same people that is realy dangerous !!!
something was allowed to ark for a long time.Leave a comment:

short on usb long term.polyfuse finally cooked down and burned.
get a pic of that area and check to see if the damage is centered on the polyfuse.Leave a comment:

No, it's from the header. Something more than likely shorted it, like damaged wires or a screw or other foreign object betting stuck behind the motherboard. The CPU and RAM are -probably- OK.Leave a comment:

It's those United Chemi-Con "KZG" caps that probably caused the explosion. Wow, never seen that before.Leave a comment:

Why did my motherboard catch fire? Also, what can be saved?
I had a minor incident with my file/media server today. I'll begin with the specs:
Asus P5E-VM DO motherboard
Intel E6300 Core 2 duo
2x2GB G-Skill DDR2-1066 ram
4x1TB Western Digital hard drives
1x1.5TB Seagate hard drive
2x2TB Western Digital green hard drives
1x500GB IDE Seagate hard drive
3x120mm Scythe front fans
1x120mm Scythe rear fan
1x140mm Antec top fan
Corsair VX550 power supply
I had done TONS of overclocking in the past (1.86GHz-->3.2GHz), and have a monster cooler on the CPU and north bridge, but it was running at stock clock speeds and voltages for the last 2 (nearly 3) years.
A pic of the carnage is attached. This machine had just experienced an otherwise record-breaking (for me) 850 days of uptime (852 I believe) and had nothing plugged into the front USB ports. I cut the usb cable off to clear the board for better picture taking and so I could check for a short in the cable and/or front panel USB jacks, no shorts were found.
As far as I can tell something to the top or top left of the USB header is what started the issue. I caught it rather quickly after the fire started as the machine is in my furnace room near an air intake for the furnace and the furnace was running when the fire started. When I got there small flames were visible.
What do you guys think might have caused this fire?
And, a related follow-up question, do you think I can get away with just replacing the board? Ideally I would prefer to avoid spending $400 replacing the CPU, RAM and maybe power supply as well as the motherboard.Attached Files -

Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

Hello forum friends.
I want to ask for help diagnosing this GPT52 LA-k201p HP 250 G8 card (without dedicated GPU).
The motherboard turns on and consumption is 2.2A (CPU fire)
All voltages seem OK.
The coil resistances are these

Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.
Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.
Fans are spinning. Blindly could install windows11 and got the device manager... -
Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.
So here is what the motherboard looked like with its original caps:
CPU VRM area up close…...
