Hi: I would be so grateful if someone could help me please:
I have an Asus X550C, running Windows 8.1. I had been having problems with the display flickering - going very dark and then flashing brighter, accompanied by a high pitched "hissing" sound (sound wasn't very loud).
I clicked on Display in Control Panel and it said the driver was up to date and working properly. However, someone (mis-)advised me to delete the driver and then reinstall, as this might stop it from doing this. Deleting driver box came up on screen but a minute later the computer froze. I tried to cancel and had no choice but to turn off at the power switch.
On turning back on, the screen briefly flashes the usual Asus text, which appears before it starts windows but after that the screen is completely blank (but the "hissing" sound is still present). If I press on the keys and move my finger on the track pad a white arrow briefly appears on screen then goes back to black. I have tried plugging an external monitor in and this displays the same as the laptop screen.
I have tried starting the laptop using a Windows 8 repair disk (nothing happens) and using a Macrium Reflect Recovery Disc (nothing happens. I have downloaded a new video driver from Asus onto a usb memory stick but cannot install it.
Please can you advise if there is anything I can do?
