PC troubleshooting

[Raznarak]

Today I turned on my pc and all went normal until my mouse and keyboard stopped working. The keyboard and mouse still had the rgb lights on, but wouldn't work. First I thought the pc had frozen, but I could see the windows clock working and time passing. I restarted The computer holding the power button down, went into bios and the mouse was lagging IN THE BIOS. I decided to clear CMOS and everything worked again until it happend again. No mouse and keyboard but pc wasn't frozen, couldn't switch usb ports, the same happened. I cleared CMOS again and an error appeared before booting into the BIOS: "overcurrent has been detected on your usb device" and the PC shut off after 15s. Then I pulled everything non essential from the motherboard and test booted it outside the case. I only connected RAM, CPU and Graphics card (I have a Ryzen CPU without integrated GPU). The same error appeared. I checked the motherboard I/O, no pin is bent. Tried to clear CMOS again, but another error appeared: "PCI vendor and device IDs do not match". After that error the same overcurrent error appeared and the PC shut off. I thought it may be the graphics card, so I Pulled the graphics card out and test booted it (without video obviously) to see if it would shut off automatically again. It did not. I am trying to resolve this for over two hours, sometimes with the graphics card on, i get no video output an it keeps running, other times i get the other two errors and it shuts off after 15 seconds.

Is it the graphics card?
Is there someway I can Try to resolve this without going to a professional?

AMD ryzen 2600
ASUS dual Radeon RX 580 8gb
16GB G.SKILL DDR4
MSI BAZOOKA B450M

Why do you say that?

I ask that now because I changed the gpu to an old one to see if that was the problem and everything was working fine with the old gpu for about 4 days, then last night I suspended the pc instead of turning it off and suddenly today I don't have video output again... Like the monitor is detecting a signal because it wakes up but no actual image...

because you error mentions overcurrent. that's most likely a faulty psu
