Windows 10: Mouse interrupts should be done in southbridge

I've seen mouse drivers writing to the registry for each position change and I know how the processor is interrupted on each mouse movement.What I'm curious about, is why Windows doesn't implement a framework by which the southbridge controller could handle the interrupt service routine for the mouse directly trap dispatching. The southbridge could send the position information directly to the graphics card via the northbridge and Windows would only need to know about the position of the mouse when another event, such as a click event on the mouse button, was registered as a different interr

Help with Hardware Interrupts

To use Krview, ignore any driver that is part of Windows or that is for the CPU idle thread.
inteppm is for the CPU idle thread, ignore it.
hal and ntkrnlpa are part of Windows, ignore them.
ati2mtag is the first one on the list that is elevated and relevant.
Find out what hardware interrupt it uses and then any device that shares this interrupt could be the problem. It might not be ati2mtag.
If its the video driver, can you use another card?
Putting the computer to sleep might reset things.

Hi Zbigniew,

I appreciate the troubleshooting steps you have tried to resolve the issue. I suggest you to install all pending Windows updates and check. Follow the steps below and check if that helps.

• Type Mouse and Touchpad Setting in Search and hit
  Enter.
• Change settings as per your requirement; click on Advance mouse options.
• Change settings under Buttons, Points, Pointer options, Wheel.

Do let us know the performance to mouse. Thank you.

 

mouse is not working right


unfortunately there isn't a lot to a usb mouse. what i would suggest is checking the power management settings on it.

Right-click the start menu and choose device manager
Expand Universal Serial Bus Controllers at the very bottom
Double-click on each HUB you have listed, click Power Management Tab at the top, and UNCHECK "Allow this computer to turn off this device to save power"
You may have HUBs called Generic and Root Hub. Perform the step above on All of them.

If you continue to have the issue, i would imagine your mouse is malfunctioning. Perhaps try another mouse just to be sure. This will help you determine if it is in fact the mouse of computer causing the issue.

Good Luck!!
