Hey guys. Three weeks ago, I assembled the computer I am using now from all-new parts. Everything works, but I noticed some strange behaviour in games. After a while, white pixels started blinking up in little bunches around the cursor and certain icons / menus in the game. When I exited and moved windows around, they would leave bad pixels in their wake. This screen here is self-made, when I took a screenshot the bad pixels would not show at all.

What I've gathered so far about the issue, and my thoughts in brackets:
- It happened in two demanding games, not at all in older 3D games.
- It happened after I'd Alt-Tabbed between the game and the Desktop multiple times (I am thinking the RAM did this, because Alt-Tabbing may tap into more RAM and then by chance reach the faulty segment)
- When I don't Alt-Tab, the issue doesn't come up, or hasn't yet.
- It continues to happen after I've exited the game, and just until I reboot (if it was overheating, it would go away quickly after the game closes. My temperatures are decent)
- I don't get any BSODs, the boot screens are all good and my monitor is fine.
- I've used BurnIn Test to determine the working state of a few components. GPU okay, VRAM okay, RAM has a single, or very few sectors that are faulty.
My question.. can graphical errors like these come from bad RAM? I've got my fingers crossed hoping it's not the graphics card. Thanks!
