I'm an idiot. I was looking to see what SSD I had, to upgrade it from 500GB to 1TB.
I saw a spare SATA cable plug/socket and decided to plug in an older 256GB SSD to see if it works.
I stupidly forgot to power down, so the PC was on when I plugged in the SSD drive, there was a spark when I removed the SSD from the SATA cable and then everything stopped.
Now it won't boot or do anything at all.
Are there any trip switches or fuses on the motherboard or the PSU?
The motherboard is a
MSI B450M PRO-VDH MAX
and the PSU is a
Xilence 700w
There is no power that I can see going anywhere, no motherboard beeps of any kind, nothing at all.
The sata drive I plugged in still has functionality, I had to reformat it but it's still working.
I'm not sure about the drives in the PC as I don't have caddys to plug them into my laptop.
Any ideas would be really helpful thanks
consider a brief paper clip PSU test; if it works, the issue is resolved.
if not: reset the CMOS on the motherboard using a jumper.
attempt to power it again.
if successful: try connecting only the CPU, cooler with fan, RAM, GPU, and PSU.
if still no response: ensure all power cables are securely attached.
So this is weird. I just tried plugging the power back in and turning it on (its been uplugged for about 2 hours)
and now I have power, fans running etc but nothing to the monitors.
The BOOT, VGA and DRAM 'easy debug' LEDs on the board are lit.
I'm not sure what that means or what to do about it.
attempted resetting the CMOS by taking out the motherboard battery for five minutes, but it didn’t help. Monitors also showed no activity, making it impossible to access BIOS. I also tried booting without connected hard drives and with just a single RAM stick, yet nothing happened.
It seems you only connected or disconnected the power cable, not the data cable, did you? (It doesn’t look like there’s a spare data cable in the box.)
The SATA power connector is meant to allow hot-swapping with different connector lengths. That’s not something I’ve ever attempted or suggested, but it’s possible your action might have led to this outcome.
I’d expect the PSU to be the issue here. It isn’t a well-known brand, so it likely wasn’t built for hot-swapping and something inside was damaged.
It would be best to swap in a better PSU and see if that fixes the problem.
The proper method for resetting CMOS is outlined in the mobo manual. Typically, short out two pins using a flat blade screw driver (while the PC is off and the PSU cable is unplugged). In my case, it doesn’t require removing the lithium battery.
A spark detected is sufficient reason to worry. It could indicate damage to the PSU or the motherboard, or possibly both. The motherboard might now be compromised. You may need to replace the motherboard and test each main component afterward.
In my experience, simply resetting the CMOS doesn’t resolve the underlying issues.
