Hey everyone!




I've been having this very weird problem since close to 2 years, basically what's happening is my mouse and display freeze for a very short amount of time every few seconds while gaming/performing resource demanding tasks on my PC.


There's some very occasional audio crackling/popping when it happens, here's an example I recorded while playing CS:GO: afadasdasdas - YouTube


Games such as CS:GO tend to be very unsmooth and jittery even though I usually get 200-400 FPS and I own a 144Hz monitor.

The funniest part is that it even happens in Windows quite often, for example I've noticed it sometimes happens while opening the start menu, launching a program or even when checking for Windows updates.




I've attempted fixing this issue for a pretty long time and nothing seemed to help.

Here's the list of tweaks I've tried already:

- Reinstalling Windows (15+ times, tried both Windows 7 and 10)

- BIOS tweaks (disabling HPET, EIST, C-States etc.)

- Made sure every single driver is up to date

- GPU tweaks (disabling shader cache/setting texture filtering to high performance mode)

- Most Windows registry tweaks (network throttling/assigning games a higher priority) so far from my experience they usually only make things worse

- Putting drivers in MSI mode




I've also measured my DPC latency and interrupts using Latencymon, here are the results:


- Main Tab: Imgur: The most awesome images on the Internet
- Drivers Tab: Imgur: The most awesome images on the Internet




My PC specs:

- Intel Core i5-6500 @3.20 GHz
- Asus Radeon R9 380X 4GB
- Corsair Vengeance LPX, DDR4, 2x4GB, 2133MHz
- MSI B150M Mortar
- Western Digital Caviar Blue, 3.5'', 1TB
- GoodRam CX300, 2.5", 240GB
- Corsair VS Series 550W



Any help is greatly appreciated, thanks in advance!
