I got my wife an Asus VivoBook X202E, running the latest Windows 8.1. It works well, snappy enough given the HDD (she won't let me put an SSD in). The problem we have is if you restart the laptop (start -> arrow beside shut down button -> restart using ) you get a black screen. The operating system appears to load, the screen just doesn't show. If you hold down the power button to turn it off, then turn it on again, it works. If you shut down completely then start up it works fine.

Any thoughts on what could be wrong? Windows update is run regularly. I haven't done a manual check of drivers, but it came like this from the factory, did it the first day we had it. It's around 3 months old, we got it from Ascent, who sourced it through PBTech.
