Is this scratching normal?

[Dial up]

So recently I have been having issues with my motherboard and I unplugged my GPU and I don’t know if scratching is normal on pcie slots, please help because I’ve noticed the same thing on my ram

I don't see anything different than the random PCIe card laying on my desk, so I'd assume yes, it's normal.

Yes, it's normal. Just oxidized layer got slightly scratched when contacting with the pins.

 

Try use compressed air can/blower blow into the slots, don't blow with your mouth.

Thanks I’m just wondering because when I switched my ram and it wouldn’t boot I thought that it was the ram because the had marks on it but it turns out it was the mobo.
