The PC fails to power on or becomes unresponsive following a cleaning process.
Hello ! I chose to clean my PC using compressed air, but it was located inside a large compressor with a filter for moisture. While cleaning, I disconnected and reconnected the HDD cables. After finishing, the PC failed to power on. All fans, motherboard lights, CPU cooler, and GPU were functioning normally, yet the keyboard, mouse, headphones, and monitor didn’t respond. The display went to sleep because of no signal. After several restarts and power-offs, it finally turned on after a few minutes. However, 20 minutes later the screen froze completely with no reaction. I had to restart by pressing the power button on the case. Once that happened, the PC became black-screened again while trying to boot. After unplugging it again and removing the RAM and CMOS battery for five minutes (holding the power button for a minute), everything reconnected. When I plugged it back in, nothing worked. The CPU was Ryzen 9 5900X, motherboard model Prime B550 M-K, GPU Palit GeForce RTX 3070 GamingPro OC, RAM 3200 MHz, 16 GB, PSU 750W.
The motherboard confirms everything is operating correctly, and no warning or error alerts appear.
All components were functioning but no signal was detected. I updated the thread and tried to assist others with similar problems. From the past two days it seems to work properly, though I’ll share an update soon. Replaced a motherboard power connector and swapped RAM slots; after that, the PC booted up successfully. I ran a short test in Heaven Benchmark for about 1-2 hours, then started playing games. The system is running smoothly for two days now—thinks it’s fixed.
No, the connection wasn't lost during cleaning. I began reattaching components once the problem appeared, but the PC still didn’t function until I reconnected the power cable to the motherboard and swapped the RAM slot.
It's strange, isn't it? I'm here to help, but I don't have the answer right now.
