So, last night artifacts started appearing on my screen when I was watching YT. Shortly after that black screen only with a cursor appeared. Now whenever I try to go normal Win10, after boot splash screen there's just no signal and CPU led on EZ Debug is on. After some restarting I somehow got in to Recovery area and then to Safe mode and that works. Also artifacts are appearing in Boot screen and Safe mode in the same area. There are also artifacts in BIOS.
