The system shuts down right after turning on
The system shuts down right after turning on
Recently, my PC tends to power up and shut down rapidly. The pattern has worsened, making it hard to start more than once every ten attempts. When I turn it on, the CPU fans, case fans, and motherboard LEDs activate briefly before stopping. After that, pressing the power button yields no effect. Only when I disconnect the power supply and let the PSU settle does it become possible again, though success remains slim. Removing USB devices and other connectors seems to improve the chances. Leaving the machine overnight and restarting in the morning appears to work better (possibly by chance). If it starts successfully, I experience no issues even during intense gaming sessions. A single buzzer sound is all I notice—it’s unusual. I haven’t modified the BIOS or CMOS battery recently, and the graphics card is functioning normally. My hardware specs are: Windows 10 Pro 64-bit MSI B450m PRO-VDH (BIOS uncertain, two years old). It’s not the newest version, but I avoid updates to prevent potential damage. The system runs at stock speeds with 16GB RAM (HyperX 3200 MHz), 8GB GPU memory (Zotac GTX 1080), and a 500GB M.2 SSD boot drive. The case uses a Master Cooler MWE750 (750W, 80+ gold).
Maybe a brief location, keep it off the main board, place it inside a cardboard box and check again
Removing the PSU was quite difficult. I unscrewed the motherboard and tried to raise it slightly off the surface, but it didn’t work. Same issue again. Appreciate the suggestion.
