[SOLVED] Ryzen 3700x and AIO install seems to have stopped my PC from displaying anything

[Chowwder]

So basically after I installed my new AIO and CPU which is the ryzen 7 3700x and the zoomflow 240x there has been no display. I switched back to my previous cpu and then my motherboard starts saying there is a DRAM error even though it didnt say that when my 3700x was in there and before i upgraded there was nothing wrong ive been trying to seek help for a week now but nothing has helped so far.
Full Specs:
Ryzen 7 3700x
TUF B550M-plus
GTX 1660 super
600W thermaltake psu
zoomflow 240x AIO
8x2 T-Force RAM

Hi Chowwder and Welcome to the Forum

From your description, did you clear CMOS prior to installing the other CPU?
Please also list the P/N or SKU of your RAM?
RAM should be checked for errors by booting from a USB with Memtest86 and run 4 passes. If any errors whatsoever then RMA the full kit.
Ensure all cabling to monitor is secure.
Please report back on the above first.
