Hello,
I am suffering a seeming catastrophic unexplained issue, and want to know if there is anything I can do to remedy the situation.
About 2 hours ago, I went to plug in an external cd/dvd drive to my pc.
(Specs:
Case: In Win 101
Motherboard: MSI B450 Gaming Pro Carbon AC
PSU: Corsair VS450
CPU: AMD Ryzen 5 2600X
GPU: NVIDIA GTX 1070
Mobo & CPU are roughly a year old
Case/GPU/PSU are say 2 years before that
)
I first plugged the USB into my front panel USB3 port (cable is USB-A to USB-B).
Then I plugged the DC power supply (which may have not been the correct Voltage/Amperage admittedly) into the socket, an extender that my PC was not pugged into.
As soon as it was plugged in my PC died, instantly losing power not blue-screening.
Connected to the previous extender are my monitors, they are still powered on.
And connected to the socket the PC is plugged into is my small server, which also seemed unphased.
Initially I hoped it may just be a blown fuse, so I tried a new cable, no luck.
Then I ripped the PSU out of my server and plugged it into my motherboard/CPU/GPU, no luck.
Finally I left everything from my old case plugged into my PC PSU except the 24pin motherboard connector, which I connected to my server, which when I pressed the on button was happy to work, all my PC fans and HDDs started spinning.
I have tried removing the CMOS battery waiting 10 mins and powering on again, nothing.
So it seems the PSU is fine. So I am left to assume the motherboard, at least has probably been fried.
But I don't understand why, if it was a power surge, how come my PSU is fine as well as everything else on the circuit, but just fried my motherboard.
Or if it was a USB power surge, I would understand how that may fry the little daughter board but the whole motherboard?
My questions are, what is likely to have happened (and how to stop that happening again)?
And should I be worried about other damage, as well as the GPU/CPU I have 2 NVME SSDs connected to the motherboard, are they likely dead?
Thanks for your help, I am sending it into a repair shop on Monday to see if they can do anything, but I don't have much hope.
Also if it helps I am in the UK so 240V if it matters.
