Question Brand new Lenovo Legion 7 screen glitch

[SpoiKey]

I just bought a brand new Lenovo Legion 7 laptop with RTX3070 and Ryzen 7 5800H. It came without OS, so I installed Windows 10 Pro and drivers myself. After couple of days however, I noticed the screen started glitching out randomly. It happens very randomly, doesn't matter if I'm browsing, gaming, watching something or the laptop is just idle. Doesn't matter if I just turned it on or the laptop was on for hours. Sometimes it's once every hour, sometimes it's couple of times a minute. I tried to completely uninstall my GPU drivers with DDU (Display Driver Uninstaller) and reinstall them using official Lenovo Support site. I also tried reinstalling my OS, during the process I formated the SSD. Still the problem remains, any tips are appreciated. I want to try everything before returning it since I cannot really be without a computer due to me working from home and also I bought this laptop in a different country so it would take weeks to return it and either get sent a new one or get the money back and buy a new one. Here is also a video I recorded of the glitch happening:

Welcome to the forums, newcomer!

Where did you source the installer for the OS?

I made an USB installer off microsoft official site, it's probably over a year old now but still worked. I also tried updating to windows 11 but the issue remains.
