Turn the laptop off (not sleep or hibernate but off).
Connect an external monitor to the laptop.
Turn on the external monitor.
Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.
If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.
If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
Sorry i had the issue the asus had with the moniter that is attached. I completely removed it about 2 months into owning it and run it via hdmi to tv. Utilising wireless mouse and keyboard.

Have reset the computer reinstalled windows. But kept my work files etc.
Updated graphics via windows device manager and immediately experinced same issue.
Will be resetting windows again, than using the update directly from AMD, as i had no issues for a year untill yesterday. Still at a loss as to what has exactly happend to initiate this issue within the 30 min timeframe between working operation and the foul up....
Failing that i will have to reset windows again but leave it as stock standard drivers.
Couldnt fix it via operating in safe mode as it wouldnt allow the amd graphic driver to load up. Which has led to this round about way to correct the issue. Damned nuisance, truth to be told but currently using it with the foxtel now glitch to recive free pay tv and watch torrents downloaded using torrdroid.
Dont have free to air tv service at current residence.
