Windows starts to stutter after a while

[Concepter]

Hello every one, I am faced with an issue that seems like its at least a few years old. And for some reason my mind makes me think I've solved it before but just can't seem to remember how.

 

The issue is simple, when you have something moving on the screen, video, movie or even game, if you don't touch the keyboard or mouse for more then 90 sec, the picture (only the video) starts to lag, sound is fine though.

I am running Windows 10 and the issue appeared a few days ago. I noticed it first on a YouTube video, and then when I tried playing a game with my steam controller. The game just starts to lag (video only) even though the controller is making some input. The only fix is to move the mouse or type on the keyboard.

What I have tried to do to fix it was :
-driver reinstall(graphics drivers, mouse and keyboard drivers, even windows update.

-Malwarebytes Anti-Malware, Registry mechanic and all sorts of anti virus and malaware software.

-Unplugged all my I/O's and let a video play, the result stayed the same, after 90 sec it starts to lag.

 

I searched far and wide on the webz, but only solution I find is reinstall, which seems stupid to me. 

Also someone suggested somewhere returning the BIOS to the default settings, and I don't understand what that is. My motherboard BIOS is stock, I've just tweeked the CPU overclock and the fan speeds.

 

I am quite out of ideas so I reach out to you guys. Hope this is the right place to start the thread.

 

Thank you in advance for your time and support.

What are the temps telling you? Maybe dirty hardware?

 

I once had a problem where the playback speed of videos was really bad. Skipping in the time line, and the screen would be to fast while the audio was somewhere completely different.

Also checked for viruses, mallware and all those things, no errors appeared. After removing all codecs and installing fresh ones, videos were fine again. So maybe look at your codecs, if the temps are ok?

 

*Some of the games I play, are using those codecs

Temps are alright. Idle is between 30-35 on the CPU, and same on the GPU. No malware detected so far.

Something tells me it was something to do with power plan's so I am going to experiment with that now.
