Board possibly damaged or processor issue detected.
It started when I needed to replace the water cooler because the old air cooler was broken. I gently loosened it by twisting slightly, which helped release the thermal paste from the CPU and cooler. After removing the old unit, I also took the CPU out of its socket. While doing that, the CPU came out too, making it hard to access the CPU pins. I installed a new water cooler and tried turning on the PC, but there was no sound or any action. The motherboard's RGB lights lit up when power was applied. I found three or four bent pins near the edge and used a needle to straighten them. A small amount of thermal paste ended up in the CPU socket—probably 6 to 7 holes. I sprayed it with 90% alcohol, let it dissolve, then blew out the residue and allowed it to dry for about 20 to 30 minutes. After that, I put the CPU back in the motherboard and reinstalled the cooler, but nothing worked. It was a Ryzen 7 CPU. Unfortunately, I don’t have a spare AMD CPU to test if the issue was with the CPU or the board. I also tried putting an older cooler back on without any changes, but it didn’t help. No beeps or signals were produced.
We need a little more info. What motherboard is it, what CPU exactly, and can you include some photos of everything?
This situation occurs occasionally. It seems to be an AM4 CPU again. That’s not typical anymore. You probably verified all connections and performed basic checks. You might have followed the advice in the troubleshooting forum thread. Refer to the AM4 pin layout—some areas are critical, others less so. If you accidentally damaged a corner with green VSS or black squares, the CPU can sometimes be removed completely and still function. At least there’s a chance issues were just missed or not fully addressed. The diagram shown is low quality and doesn’t cover much of it. When installing coolers, do the mounting screws have springs underneath? If not, you might over-tighten or loosen unevenly. Unless you used a X-pattern or gradually tightened each screw before moving to the next. Have you done cooler installation before, or is this your first attempt?
Cooler includes springs beneath the screws. It was difficult to locate the exact screw to install because the area wasn’t visible. Only two screws were needed—one on each side. This is my first time setting up a water cooler for the CPU, having assembled five or six PCs before. The old CPU cooler brackets had to be removed since the new one didn’t fit into those holes. The new bracket was secured gently. From what I learned, the system should still power on even without the cooler attached to the CPU. It never turned on, so overheating from the cooler wasn’t the issue.
The cooling system's pressure on the CPU can lead to complete failure. I've noticed something happen when a screw is tightened suddenly—everything stops abruptly. This isn't about temperature issues; it's about the CPU being forced too hard, damaging the connections.
The CPU got stuck against the pump during disassembly. After reinserting it, the system didn’t respond. When you opened it again, you saw the pins—yes? Edited July 1, 2025 by leclod
I've also tested it without a cooler, just using the CPU alone. Still nothing. I stuck to the CPU air cooler. Installed the brackets for a water cooler, applied thermal paste, attached the cooler, and plugged everything in to try starting the machine. No response—no fans spinning at all. When I took it apart, I saw bent pins. I tried reinserting them without the cooler on, but it didn't work again.
