Question No signal to my monitors after changing GPU ?

[MrZ33k]

Hi everyone,

So I upgraded my GPU today from Nvidia to Radeon. Before doing so I uninstalled the drivers with DDU (I think that's its name) in safe mode. Once doing so I powered everything off and unplugged power, changed the GPU, plug everything in and now I'm getting No Signal to either of the monitors ?

Since the problem has come around I have Reseated the ram, installed old GPU back in, changed cables, tested monitors on different system (works fine), cleaned all vents and dust away, reset all cables to do with power, removed CMOS battery and still nothing. All the fans are working, all the LEDs are on and USB ports are working.

Could anyone give me a hand with this as I'm stumped as what it could be.

Here are my specs:
Motherboard-Gigabyte Z390 Aorus Elite ATX LGA1151
CPU-Intel Core i5 9600KF 6 Core LGA 1151 up to 4.6GHz
GPU-Gigabyte Radeon RX 6800 XT Aorus Master 16G
Ram-Corsair 16GB (2x8GB) CMK16GX4M2K3600C19 Vengeance LPX 3600MHz
Monitors-Acer LED Gaming Monitor 75hz Freesync HDMI
PSU-1200w Powercase PSUPOW1200max

connect the monitor to the gpu?
is this a modular psu? check the pcie power cable on the psu end?

Monitors don't work in any port, GPU or motherboard. Nar not a modular PSU so can't be that.
