(GTX 1080ti / i7 7700k / 16gb DDR4) Games play fine, but desktop and Youtube? Oh boy...

I have recently came across the most odd thing I've ever seen in my 20 years of building PCs. I have a non OC 1080ti with a non OC 7700k pushing 4.2ghz. As you can imagine I can play almost anything under the sun maxed out with no issues whatsoever.

HOWEVER...

Up until recently when I exit the game, the entire system slows down dramatically. Youtube videos stutter, even the cursor stutters when moving across the screen. Resource monitor doesn't show anything crazy and GPU temp shows the GPU is using like 5% memory.

I've tried everything from reinstalling the GPU driver, to rolling it back, to reinstalling windows. Nothing seems to remedy it, EXCEPT restarting my system. The games themselves show no stutter at all, only when I exit them. When I run Heaven benchmarking while the system is "bogged down", even on extreme it shows 180FPS, but it LOOKS like 15FPS. What gives?

I'm at a COMPLETE loss. Hope the fine folks here can point me in a right direction! Is this even a GPU issue?

EDIT: I completely forgot, this is also a legit copy of Windows 7.

What about CPU temps under load? It might be throttling back if too hot.

Also, try installing Windows 10 - you can keep it in trial mode for awhile. If that makes all the difference, then perhaps something has changed in the nVidia driver base to "break" Windows 7 performance.
