Windows 10: Windows 10 Input lag problem!

Hello Windows,


Since march/april 2018, I got a very annoying problem. I explain : I got a mouse lag (delay, latency) on my desktop and even in games. To be more precise, I'm having a small but very annoying delay when I move my mouse.


Here's what I did :


Reinstalled windows several times, 3-4

Updated all my drivers

Uninstalled my GPU nvidia drivers and reinstalled it

Bought a complete new PC

Bought a new mouse

Bought a new carpet

Bought a new monitor (from a 60Hz to a 144Hz)

Checked for windows updated

Checked for process on the background

Disabled mouse ehancement

Disable inactive windows mouse

Also disabled Cortana

Did a clean boot

And I booted my PC without my GPU also

Also booted my pc with ram by ram


So now I can confirm that the issue isn't hardware related.



After all of thoses step, I still can't believe that I'm stuck with this very annoying issue.

At first I thought It was a virus : I reinstalled windows 10, even bought a new HDD

Then I tought it was my processor or gpu : bought a more powerful cpu and gpu

Then I thought it was a power supply issue : bought a new and more powerfull PSU (from 500W to 750W)

Then I thought my monitor was causing the problem : bought a new monitor with a higher refresh rate

And finally I thought that my mouse was broken : bought a new gaming mouse (G403) + a new carpet for her


I'm very lost, and this issue ruin my gaming experience since now 5-6 month.

I came to the windows forum because now, since I changed everything, I'm convinced that it has to do with windows 10.

The windows 10 version 1803 came out when my issue started, so it might not be a coincidence.


So, I'm very open to every answer...



SPECS:

GPU : GTX 1070TI 8GB VRAM

CPU : i5-8600K 3.6GHz 6core

RAM : 16GB RAM DDR4 3000Hz

MOBO : Z370 HD3

PSU : 750W CoolerMaster Bronze 80+

Monitor : Acer 144Hz (with display port)

Keyboard : Logitech K120

Mouse : Logitech G403

Carpet : Logitech G440

OS : Windows 10 Home V1803

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.

 

Input lag?

• So I had to install the last fall creator's update because of mandatory security updates. Sometimes I launch tf2 and there's major input lag while other times there isn't. I used to have a solution of reverting to a version before the fall creators update
  but I've tried that recently and I needed to reinstall Windows 10. Another solution was to just restart but I don't want to have to restart my laptop every time I want to play video games. I don't know what's causing the input lag, whether it's because of
  the game or the OS or Logitech Gaming Software (which might not be the issue since I had this issue way before I ever got a logitech mouse). I suspect it's the OS and the fall creator's update. I need a permanent solution to stop this input lag. If anyone
  has one, I would really appreciate it.
