Question Motherboard gives a constant VGA error and I can't boot into the BIOS or Windows ?

[Koen st]

My MSI MAG B550 Tomahawk gives me a cpu error for a few seconds and then gives a constant VGA error, this happens after I unplug the power cord. and to be honest I dont know what to do here, I have already updated the bios, tried to use an older GPU, gtx 1050, I have switched the CMOS battery. this is the second time I have had to fix this issue and I don't know what I did the first time to fix it, but when its fixed and I don't unplug the power cord it works fine and as it should. Could somebody help me and figure out how to fix this problem?

PC Specs
Mobo: MSI MAG B550 Tomahawk
RAM: 32GB DDR4-3200
CPU: Ryzen 5 5600X
GPU: AMD RX 6650 XT
(tested it also with my old GTX 1050)

Which CPU ? BIOS version up to date?

Which CPU ? BIOS version up to date?

my cpu is a Ryzen 5 5600x and the bios is the latest non beta, so yes

UPDATE:

i have made it so that the pc will boot reliably with the gtx 1050, I dont know about the RX 6650 XT, im too afraid that it doesn't work, and I cant enter the BIOS or windows or the boot menu with the RX 6650 XT.

Any idea how old it is?

When the 6650 XT was installed, did you connect the PCIe (6+2) connection from the PSU to it?

Also, double-check that both the required 8-pin and 24-pin power connectors on the motherboard are firmly attached.

i have no idea how old it is, its my second pc and it is second hand, but I do know that the 6+2 connector is good and both the 8- and 24-pin are firmly attached to the motherboard

Sometimes there is a manufacturing date on the label of the PSU.

Have you tried the 6650 XT in another system?

Understood. Intent was to isolate the issue.
