My pc does not give input to my monitor

Recently i had to swap my motherboard because on my old one i did a Bios update and apparently the update killed it. i bought a Gigabyte b450 aorus i pro wifi. only problem is that my pc does not give input to my monitor i've tried

• removing my gpu and plugging the hdmi cable to my motherboard
• putting the hdmi cable on the motherboard while the gpu was in
• cleaning the ram with a brush
• checked if all my cables are plugged in properly
• tested my monitor and cable with a console
• started it without mouse and keyboard
• i know its booting up to windows because after a bit my cooler changes color from white to purple, i have nzxt cam installed and it runs at boot, everytime i run the program the color on my cooler goes from white (default) to purple (the one i customized). i really don't know what to do if there's something i can do please tell me
• my components are:
• gtx 1050 ti
• ryzen 5 3600
• gigabyte b450 aorus i pro wifi
• an nzxt kraken m22
• a gigabyte 1tb ssd
• corsair vengeance 8 gigs dd4 ram (x2)
• 450w psu.
