Motherboard -> HDD -> Windows -> Prtscrn
If we look at it like this, Prtscrn is a Windows exclusive command and therefore the problem is probably being contained in Windows itself. It takes whatever the computer has drawn in its current state and copies it to the clipboard. Therefore, the problem is probably contained within Windows itself. What could cause graphic distortion would have to be related to the graphics card, which has software that Windows uses to control the Graphics Card, if I am thinking about this correctly. What could mess with drivers? The Hard Drive being corrupt, or maybe screwed up is a possibility, which would load the drivers off of the disk improperly. If the Hard Drive itself isn't fucked up, then maybe the motherboard is processing the hard drive's contents improperly, and executing it in Windows improperly by extension.

The problem is that OP hasn't mentioned any other Hard Drive related issues, so I think I might be wrong on this one. But I feel like I'm not too far away from the answer.

just my 2cents, I probably have no clue what I'm talking about.
