Hello
I am having the same problem as kingofthesofas, some problems with the mouse beeping and all and the lagging, and usually before this though there's like a flash on the screen as if something is up with the video driver for a second. Funny thing is I can use the keyboard, and both the keyboard and the mouse are usb 2.0. And you never know when it's going to happen.
I'm running the beta version of Windows 10 build 10041, so I know I should be posting on the windowsten forum there, but this is driving me nuts. This never happened when I used 8.1 or even the previous build of Windows 10 build 9926.
I hope you find a fix kingofthesofas, and good luck in doing so cause I been looking myself for a clue to this. I'm hoping it's just Windows 10 10041 not quite agreeing with my hardware...
I hope on my part there's a new Windows 10 build SOON
