Weird power problem

Status
Not open for further replies.
Hello there everyone.

I have a problem with my setup, last week it went off suddenly and went to sleep. I'm always turning off my PSU because sometimes my PC "tries" to power up by itself for no reason, so that day PSU off as always.

The problem came the next day, as soon as I powered up the PSU the system went on but with no video signal and the debug LED "CPU" turned on. Frontal panel not responding, so the only way to shut it down is to power off the PSU. I discovered something today: taking the power switch off, powering the PSU and starting the PC with a screwdriver on the power switch pins does the trick, everything normal.

I really want my PWR Switch back but I don't know what the hell is happening.

Basic setup information:

PSU: Cooler Master MWE Gold 750-V2 80 PLUS Gold, 24 pin ATX, 120mm, 750W
Motherboard: Gigabyte x570 Aorus Pro Wifi
CPU: Ryzen 5 5600X
Case: Fractal Design Meshify S2
RAM: Crucial Ballistix 2x8 GB

Thanks for your time.
