There's a problem with the graphics card

[JinWoong]

This time, I bought an Intel graphics card secondhand.
I was using the basic part well, but I would like to inquire because there is a noise in the edited video when I see a green screen in the video or when editing the video

And I'd like to know where I should visit if I do A/S in Korea

Lastly, it asks you to enter 'serial number/batch number' and 'serial number/stalking ID/SA#' to register the product or check the warranty period. Where can I find these?
I have a QR code and a number starting with 'ADNF' written on the box.

Since you are the second owner of the  card, there is no warranty.

1. Update Intel graphics drivers and ensure proper ventilation to fix video noise.
2. Visit authorized Intel service centers in Korea for A/S.
3. Find serial number/batch number on the product and contact Intel support for SA# assistance.

If you purchased it secondhand, you have no warranty. The warranty is only valid for the first owner.
