Hello. I've got the same problem with Windows 8/8.1 with the last release of Windows 10 (100122), it freezes or shutsdown ramdomly. My guess is an issue with the video, because some times appears some squares or a green line in the left side of the screen. It works perfect with Windows 7. I've tried everything in the BIOS, but no luck. Any ideas? Thanks! PD Zeenbook its a Intel Core i5 (2nd Gen) with integrated Intel Graphics HD 2000 with 4 GB ram and 128GB SSD.
