Hello,
Today my washing machine completely broke down. My parents desperately tried to get it working, but it resulted in the circuit breakers tripping and my server (an old Dell Wyse thin client) experiencing a hard power off.
When I tried to turn it back on, I received these errors on the screen.
I ran a memtest, and it completed without any issues. I also created a disk image backup just in case.
Is there any chance of getting this machine running again, or is it only fit for utilization?
Most likely there was either a hard voltage surge or a hard voltage drop. This could damage the PSU irreperably, or any parts connected to it and the computer. Make sure to use this thing with a grounded electrical socket.
Looks like two RAM addresses failed when the machine crashed, and so did TPM communication. If your machine has a dedicated TPM, you can try removing it and see if that resolves the issue.
The red dots everywhere are not a good sign. They could be signs of an iGPU failure, or yet more damaged RAM.
You’ve said your RAM passed a memtest, so I’d start thinking the problem is conditional. Perhaps the CPU cache is broken (resulting in bad RAM) or the motherboard itself only makes good contact once it heats up and expands from running for a while.
It’s also possible that one of the capacitors blew. Check the motherboard for any leaking/burned/puffed up capacitors. If you see damaged capacitors on the motherboard, someone with soldering skills may be able to replace them to get the machine back up and running. Same with resistors and other physical components. If you see damage in surface mount components (the very small black squares on the motherboard, RAM, or CPU) you likely won’t be able to fix the issue. If you want to try anyway, see if you can find) order the exact spec component online (you may need an electrical diagram of the motherboard for this) and look up how to reflow solder with an oven.
You could try another power supply as well, bad power supplies can cause all kinds of issues like these.
There are also capacitors in the power supply. Do not touch those, even after powering down the computer and removing the plug. Just the slightest bad touch and you will get a severe electric shock risking instant death on the spot, unless you’ve been educated in dealing with high voltage soldering and have the appropriate equipment. Power supplies are designed to be completely safe as as long as they’re grounded and you don’t go poking inside them. Leave that thing closed up and connected to ground, and you probably have no need to worry about that stuff while working on the computer.
