Why is it not booting?

[O.P.Mager]

First the specs:

Gigabyte GA-970A-DS3P
AMD FX-4350 4.2GHz
Asus GTX 1050ti
Arctic Freezer 7XCO
Yongxinsheng 8GBx2 DDR3
BeQuiet System Power 10 650W

Now the problem:
If i hit the powerbutton the fans spin up and both processor and the heatsinks on the board (VRM?) get hot fairly quickly but i get no visual output and i already checked the Graphics card in a diffrent system and it works fine. Any idea on what this might be or what next step i should take in finding the issue?

Given the age of the hardware, I assume this is either an old, old rig, or purchased from used hardware, correct?

Make sure you're at least on BIOS F1, double-check all the mounts for the cooler and such, ensure it's all plugged in correctly (make sure monitor is plugged into GPU). Outside of that, my usual tricks are things like test the RAM in another system or different RAM in that one, etc, etc. won't work here really because most folks don't have this age of hardware still lying around. If you do though, definitely cross test.
