Question GPU won't boot but it will boot on another PC ?

[xtargetx]

As the title says, my GPU won't boot if installed on my PC, but it will boot if I install it on my brother's PC.

My specs
CPU: Ryzen 5 4600g
CPU cooler: coolmoon T6
Motherboard: MSI B450m
Ram: 16gb ddr 4 3200
SSD/HDD: 500gb ssd and 3 tb HDD
GPU: RX 6600
PSU: Corsair CV 650
Chassis: I think its a rakk chassis
OS: Windows 10
Monitor: an Nvision 1080p monitor

Initially, we thought it was the mobo so we replaced it with a new one. Still won't boot. Then I replaced the PSU, still won't boot I updated drivers, still won't boot. I checked rams still won't boot. Restarted Cmos and reseated GPU and it still won't boot.

I know the CPU and mobo aren't the problem because it boots just fine if I use the 4600G's IGPU. The GPU fans also spin.

I'm not sure what to do at this point. Please help.

PSU: Corsair 650W
Corsair is the brand of the unit while 650W is the advertised wattage of the unit.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

What is it doing exactly? "Won't boot" by itself isn't enough if a description to know where to start.

Like plugging the HDMI to the GPU would lead to a no signal from the monitor

Okay but is the computer powering on? Are there any lights on the motherboard indicating it's not posting?

Need the motherboard model and also PSU model. If PSU is modular check both ends of pcie cable is properly plugged in. Pcie slot provides power as well so that's enough for GPU fans to spin but if pcie plug is slightly off either side you won't get a display.

Try update bios also.

Yes because it has image on the monitor if I switch the HDMI to the IGPU/Mother board HDMI Port

Unfortunately the mobo is non-modular. Though I have a CS 650 and a CV 650 and I used both to test it and still nothing.

Mobo? I assume you meant psu. What is your motherboard?

Try update bios. And really check pcie connector it is being pushed in all the way.

With GPU installed connect monitor to motherboard. Start the system, once in Windows go to Device Manager. Is 6600 appear there? If so are there any error codes? Run GPU-Z. See if it detects 6600 and if yes what it finds about it.
