Detailed description：The laptop freezes up and screen jumbles. It can happen when I first power on the laptop and it will freeze immediately on the ASUS logo. It can happen during boot, it can happen as i'm logging into Windows or during use within Windows. No particular application causes the problem.
It does not matter if have an external display connect as it happens with or without it connected.
I have completed a factory reset and it happened during the reboot cycle.
I can go a few hours sometimes before it happens.
