Windows 10: need help tracking down a bug

once a minute, something on my computer is causing a GPU usage spike which causes the computer to be unresponsive for a few seconds, in all apps.

tried reinstalling drivers thinking that was the issue, and even tried installing an older nvidia card instead of the amd one, but the problem was there regardless.


the following processes start when the spike happens then end before the next one.

taskhostw.exe

dllhost.exe


any video, be it dvd, saved file, or streamed in a browser will play as normal, but he playervlc/mpc/wmp or browser will be unresponsive. games of any intensity will visually stop for a few seconds then chug to catch up.


when switching the drivers and video cards i used DDU in safe mode to remove the drivers.


i thought i could use event viewer to tell what is was, since its happening in the first second each minute, but its either not showing up there as an event, or i dont know how to configure to find it.


which brings me here. can i get some advice to find and hopefully fix this issue?

:)

 

Taskbar bug: switching to another window -will not appear at the front


Follow either of these steps to fix the issue with the Active window hiding behind.

Method 1:
I suggest you to disable window by hovering over it with the mouse and check if it helps. To do so I suggest you to try the below given steps and check if it helps:

1. Press Windows key + X key and click on Control Panel.
2. Select or click Ease of Access.
3. Click or tap onEase of Access Centre.
4. Click on Make the Mouse Easier to Use was uncheck Activate Window by hovering over it with the mouse.
5. Check if issue is resolved.

Method 2:
I would suggest you to completely uninstall the touchpad driver and reinstall it. Kindly follow the below given steps.

1. Press “Windows key + X” and click on “Device Manager”.
2. In the list of devices, you should see the touchpad drivers.
3. Right click on the device and then select "Uninstall".
4. In the uninstall dialog, make sure you select the option to delete the driver package from the system. This causes the driver package installed earlier to be deleted.
5. In the Action menu of Device manager, select “Scan for Hardware changes” option. This will cause the device driver to be reinstalled. Once the driver is installed, close all windows and restart the computer.
