Hello, few days ago my pc randomly restarted and my MBO started showing VGA debug led, after that I pulled out GPU (RX 5500 XT) and pc booted fine on Vega 8 on my Ryzen 3 2200G, after that I installed my old Nvidia GT730 in PC and it again worked fine and to mention GT730 doesnt need ext psu cable, so after that I took my RX 5500 XT to a friend house and installed it in his PC and again my GPU worked fine, so I tought its PSU and I got new one but only to find out its same error all over again

Are those two compatible together even tho they worked fine for a month?

I tried all the usual stuff like CMOS clear and reseating everything inplace even CPU nothing helped so far.

Clear CMOS.

Also please list all your components make and model including your old PSU.
Ryzen 3 2200G
Kingston HyperX 8gb 2400Mhz
Gigabyte RX 5500 XT Gaming OC 8GB
MSI B450M Gaming Plus
Intel SSD 5 240GB
New PSU -> Corsair CX500
Old PSU -> Silverstone SST-ST50F-ES

Also I tried clearing CMOS
 
I wouldn't have bought that PSU, the CX500 "Builder" model (https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/cx-series-config/p/CP-9020047-NA#tab-overview) is a pretty bad PSU really only suited for office type PCs.

The CX550 https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/cx-series-config/p/CP-9020121-NA or CX550m https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/cxm-series-2015-config/p/CP-9020102-NA are much better units.


Saying that it should power the 5500XT at least enough for it to turn on. Boot with just the 2200G installed then uninstall the 5500XT drivers along with Nvidia driver if they are present power off. Reinstall the 5500XT making sure that monitor is plugged into the 5500XT and see if it will boot. If it does download and install the latest AMD drivers for it and you should be good to go.


You can also download and try DDU (Display Driver Uninstaller) which is a program that will completely remove all traces of both AMD and Nvidia Drivers. You must start in safe mode to properly run the driver uninstaller.

I gave it a shot and did all above but no luck, pc restarted 3 times but after that got stuck on vga led again

About PSU it was only thing available in this corona time for me but it should be enough to atleast get it to desktop

If I didn't mention it so far my fans spins up and they stay on low rpm whole time as well as gigabyte logo lights up, also if I leave it on for longer period of time on debug led state my gpu gets very hot even tho pc is not even booted
