A computer shut down unexpectedly.
A computer shut down unexpectedly.
I was gaming Minecraft when suddenly my PC shut down unexpectedly—no power surge, just it just turned off. When I tried to restart, it didn’t come back. I plugged in the power cable and outlet again, but it still wouldn’t turn on. After a few attempts, it started smoking and sparks flew, so I unplugged it. Now I’ve disassembled everything and checked, but nothing looks faulty. I reassembled it and it works now, though the motherboard shows a red CPU light and a yellow DRAM light. I’ve tried all possible fixes and need advice.
I’m not sure about the exact spot where the sparks and smoke originated. Examining those spots closely would help. Also, checking all power connections—like the PSU to the wall or any surge protectors—is important. I wouldn’t recommend testing it further, as it might worsen the situation and damage other components. The CPU and DRAM indicators aren’t clear enough to determine the source accurately. My initial thought is the motherboard, but I’d suggest investigating the area with sparks first.
I searched for their origin in the hut but didn’t find any clues. I brought everything back, and now the PC starts but the CPU and RAM connections remain active while it won’t boot.
Switching the motherboard and CPU didn't fix the issue, so it's likely the PSU is the problem.
Absolutely, this power supply is definitely faulty. I’d swap it right away and cease using it entirely until you obtain a replacement. It’s possible you caught it early, but there’s a chance you might damage other components in the process.
It depends on whether your current motherboard supports both CPU and DRAM lighting simultaneously. If it does, then both lights should activate together. If only the CPU lights up with the new board, it might mean the DRAM light isn't compatible or is disabled. Check your motherboard's specifications for compatibility.
It seems to be the PSU, but probably not. My prediction would point to the power solutions built into the board. On the older model it might still supply power to the memory, while the newer version could be blocking it. Alternatively, it might involve other ways of activating or controlling those lights—something worth checking further if it isn't the PSU.
