I had a similar issue with mouse freezing after updating my Lenovo Yoga 500 to Windows 10.I've fixed it by renaming C:\Program Files\Realtek\Audio\HDA\to something else.It doesn't kill the sound on your machine nor does it make any difference in sound quality as far as I can tell. It seems that Realtek was really impairing the system for me."I fixed mine by doing the following: Open task manager, go to the startup tab and disable the Realtek HD audio manager.Reboot the machine." THANKS, this worked perfectly fine with my Lenovo Yoga 300!!I noticed that it will lag on one monitor but won't on the other.
It came with Windows 8.1, but I updated to Windows 10 on Saturday.Edit: I managed to solve the problem again by removing the update KB3081438.I've got a lenovo y50-70 and the mouse driver is also freezing for me, can't scroll aswell. Try checking this out: I sorta just started relying on the updates.Specs: Intel Core i5 5200u Nvidia Geforce GT 940M 2GB8GB RAMLink to Best Buy listing Thanks for the help, sorry for so much text, first paragraph has the main info, rest of it is just to eliminate some answers I'm sure I'd get. Didn't work for me, however, I checked for updates and installed one that was pending, which solved my problem. I would make sure that there are no pending updates, then uninstall recent ones if that doesn't resolve it. There is evidently an incompatibility between one of the updates and the Realtek sound manager.I fixed mine by doing the following: Open task manager, go to the startup tab and disable the Realtek HD audio manager. Or, you can go into processes and kill the process for it.
