Question Fans running. No signal . Please help.

[xCJ11]

My PC was running fine until recently ,
The PC fans light up and run but theres no signal whatsoever ,
Keyboard doesn't light up , mouse doesn't light up , and there's no signal from the graphics card .
What's going on ?? 😭

What I tried -
Removed the CMOS battery and inserting it again

Removing my CPU , reapplying thermal paste and inserting it again

Removing my GPU and using the integrated graphics by connecting the HDMI cable to my motherboard

Removing one ram stick and running just one , still doesn't work

None of these worked , my PC just turns on and for some reason the GPU runs at Max fan speed and absolutely no signal from the PC
Any help?

Have you tried using one stick of ram at a time?

ok I believe your motherboard has died. You can try unplugging all external peripherals such as keyboard mouse, ssd etc and see if you get any change.

Died ? Is that why my GPU and CPU fans are running at full speed?

But my motherboard lights are on too, and even after disconnecting the peripherals , there's no signal to my monitor and the fans are running at full speed

Remove the video card and try the motherboard graphics.
Borrow another power supply the one you have is garbage.

I have already tried all these options..
Also this is my only power supply I can't really get another.
This is really frustrating? Is it the motherboard or the psu
