Hello friend,
I did allot of research and found out that GPU Artifacts only appear after a vert long duration of using it. And in this case, my GPU is just used for 10 days exactly; and it's not reasonable for a GPU to die in this short period.
I tried to downgrade my Windows 10 Version, didn't work. But I figured out where the problem is coming from. Something scratching that part of my mind and remembered that I used some Regedit (Windows Registry Edit) to improve fps in some games. So my solution was installing CCleaner (Download here:
https://www.ccleaner.com/ ); After that, ruin CCleaner and follow these steps:
Step-1: Select Registry
Step-2: Scan for issues
Step-3: Fix all selected issues...
