Hello everyone, my computer shut down unexpectedly one evening while it was in sleep mode. When I tried to turn it back on, the next time I wanted to use it, it wouldn't respond. I attempted this around 15 times without success. During those attempts, the fans ran at full speed, the GPU lights turned on, but I couldn't use the power button to shut it down—had to use the PSU power switch instead. I experimented with a different power supply and RAM, but neither worked. After re-seating the CPU, the system managed to start briefly before hard shutting down twice within a few minutes. It hasn't booted again since. I've reset the CMOS several times, even replaced the battery, and disassembled/rebuilt the whole system. I started it with just one stick of RAM, no peripherals connected, and checked Event Viewer after the first shutdown. The logs showed only that the system didn't shut down properly. I also lack a motherboard speaker and can't test my CPU or GPU elsewhere. It seems something is likely failed, probably the motherboard itself. I was hoping to confirm if I missed a simple fix because swapping the board would require a full platform upgrade. My current setup includes a Ryzen 7 2700 with cooler, an Asus Prime X370 Pro motherboard, MSI GeForce RTX 2060, 16GB Corsair Vengeance LPX RAM, EVGA 650GQ PSU, 1TB SSD, and ADATA SX8200 Pro.
I rebuilt the entire system both prior to and following the mini-revival.
This might indicate a weak power supply, likely coming from the motherboard. Have you confirmed you don’t have another board to try?
It seems like you're facing a unique situation—most repair shops don't specialize in AMD-based systems.
Boards are often responsible for such issues, but don’t stress. You can usually get one in good condition for 50 to 70 dollars. It’s unclear exactly what causes the board to fail, but it seems like a last resort fix might work since you have no other options. Remove the board from the PC without any attachments, then disconnect the CMOS battery, short the clear button and power button using a screwdriver for about two minutes each. Next, soak everything thoroughly by running water over it. If possible, submerge it in a bucket of water or run it through the dishwasher without detergent. Allow it to dry for about two days, though tropical areas only need a day. This deep clean should help if any grime is affecting performance. Interestingly, I haven’t destroyed any boards with this method—most often the problem lies in not properly discharging the board. This approach has proven effective even after five dips, though the persistent shutdown issues still make it reliable for testing. I didn’t list it for sale because it’s still functional after repeated attempts.
