So my pc was running and I had a nap when I came in the room the leds ( fans and all are with leds ) where on and all the fans are on full blast , black screen and the off button on the pc didn’t work , so I did cut the power . After that I try to turn the pc on , all the led are on and just one fan where running . I turned it off pulled out the gpu checked some cables and pulled the ram out and put it back it . Than I put a new bios batterie in . Now all fans are running when I turn on the pc but still black screen .
The LEDs that show you the status of the mother board CPV VGA and so on are not on .

I pulled the gpu out and put it back in .

The on Button still just turns the fans on and nothing is happening beides fans on and LEDs on .

Pc is rather new got it just last year so yeah … shitting situation

I am a bit angry that I let the pc run while I was napping but I was not expecting that to be an issue
