Hello there,
Have you tried updated your drivers since you upgraded to Windows 10? http://windows.microsoft.com/en-gb/windows/update-driver-hardware-isnt-working-properly#update-driver-hardware-isnt-working-properly=windows-7
I would also suggest you to boot the computer in a clean boot state and check if the issue persists. This step is performed to check if any other background service or program interfering and causing this issue.
Refer to these article to boot the computer in a clean boot state: http://support.microsoft.com/kb/929135
Hope this helps!
