PC stopped booting suddenly

[yasincengiz]

Here's how it went down. I was thinking about changing my CPU cooler but because there were no correct cpu cooler height available for my case I decided to open the side panel and measure it my self. When I looked at my screen it was gone completely black so I pressed restart button and it didn't work tried turning it off with the power button didn't work as well. Only way I could turn it off was PSU switch. After that I tried turning on the PC but it doesn't even boot to BIOS, I have a mobo speaker the "beep" sound doesn't come as well. I tried plugging off rams, plugging off all USB ethernet speaker except keyboard nothing worked, plugged out everything except CPU, CPU cooler, 1 ram still not booting. Can anyone help me It's really frustrating PC was working fine for months.

 

Mobo: Gigabyte B450M S2H

CPU: Ryzen 5 3600 stock

GPU: Asus Turbo 1080Ti

RAM: Corsair vengeance LPX 2x8gb 3000mhz

PSU: Zalman 80+ 700W

 

I included a video showing everything works yet no boot.

Edit: I still cannot power down the pc with the power button It opens it but I have to use PSU switch to power it down.

Could it be that you just disconnected the power switch from the motherboard by mistake ?
