Ok so sorry for not being detailed on my original post.
I have a MSI MoBo
AMD CPU
Just got a Nvidia Quadro FX 5800(yes I know it’s not that great)
But when I boot nothing shows on the screen and the fan doesn’t even spin. LEDs on the GPU come on and everything. But no response or anything from it. Any ideas?
If any other info is needed let me know.
P.S- I Am new to this....

Step 1. Remove the GPU and try through the motherboards video ports to make sure the mobo is working. If you get no signal like that check RAM is in the correct slots then try again, if no joy still then try with only 1 stick of RAM in the primary port
