Ryzen 5 2600 new build no screen on boot

[ConnorBazinga]

Hi,
I've recently built a new computer. not my first build and never had any issues before.
However this one, I've put together as I always do, tried booting it but am just getting a black screen on my display and nothing else. Fans are spinning, lights come on, everything looks like it works but can't figure out the problem.

Ryzen 5 2600
Asrock b450 pro4
8gb ddr4 crucial single channel
Xfx Rx 570 black edition 4gb
Aerocool integrator 700w modular PSU (80+ silver)
Adata 240gb SSD


I've tried everything on the internet such as reseating ram, checking connections, clearing cmos, etc but nothing works...can someone please help?

Is your monitor plugged into your GPU or to your Motherboard? (It should be on the GPU directly)

Tested ram in all slots? Preferred is mostly the second from the cpu.

Try to get dualchannel ram with Ryzen,might even want to consider sending this back and get a 2x4gb kit,but maybe in your country kits are really so much more expensive.
