Question NO SCREEN SIGNAL

[OUDAIKOKASH]

Hello,

So my pc was working perfectly, i've bought a new fans for the case, i installed them and everything went smoothly! but when i turned the pc on all fans ran so freaking fast and the screen can't get a signal!

I've tried so many things!

1- CPU resetting
2- BIOS Battery changing
3- Disconnect everything and reconnect again
4- unplug everything connected to the pc and press the power button for 2 minutes
5- i've changed the Power cable and the HDMI cable

So plz guys any tips? what do i have to do ? did i just killed my motherboard ?
