I have a user with a Lenovo X1 Carbon running Windows 8 Pro (Latest version and updates). The last two weeks almost every other day when he comes in it will just boot to a solid blue screen and just sit there. Today after manually rebooting it a couple of times I just went into the bios, didn't select anything but just hit F10 for save and rebooted. It booted up properly. We are concerned that when he takes the laptop on the road that this may happen and he will be unable to use the device. What could be causing this issue?
