confirm either the disk is SATA or IDE thenn open at the back of your laptop and you will find a cover with a picture of a cylider like then open it and carefully slide out the hard disk and install the new one and load the operating system.

If recovery doesn't solve it (F9 at start up, Asus logo), You need to send it in to the repair center for touch firmware update/lcd replacement.

There's no optical disk drive installed on this series.

Admittedly, the placement of the "END" key is odd in the location where the "NUM LOCK" key would normally be. However, if you look at that key closely you will note that there is a second function to it. Hold down the "fn" key and press the "End/num lk" key and the numbers will be turned on.

The issue might be corrupted display drivers, I recommend you to boot the laptop in safe mode by using F8 key and if you are able to get into safe mode, update your display drivers and update BIOS.
