Video seizes up after running for some time. Usually it will last for a half an hour to an hour, before freezing. The time to failure seems random. Occasionally, but rarely, the video will recover without sound. The only sure fix is to log out and restart the computer. It nearly, but not always, works the first time. My Acer has Windows 10 and is about 6-months old. I don't know if it's related, but the Bluetooth app is dropped occasionally. A reboot doesn't help, but it does sometimes recover after a few days, for no apparent reason.
