Answer to: Why is My Computer Freezing?Had exact same problem with the Yoga 3 freezing any time you move the screen forward, unless you disable the network card. Driver update didn't help. Was about to open it up to make sure nothing was loose. Turned the laptop over and noticed that 2 of the screws near the hinge were a bit loose. Before doing anything else, I just tightened those screws and checked - PROBLEM FIXED. Just having the case loose was enough to cause the problem. A very easy thing to check before wasting a lot of time and money.
