Actually I found something which you should try first.

This happens when these services are stopped :
1. NVIDIA Driver Helper Service
2. NVIDIA Update Service Daemon.

Start Task Manager .Click the tab "Services" .Click on a button named "Services ..." .Find them.their names .Right click on them .then Properties . Then Click on "Start " and then select Start-up time :
for the first ->Automatic
for the second -service > Automatic(Delayed Start)

Doing that , it would run

Give it a go. It might work mate :) You could send it to the manufacturer if you can't fix it.

Oh sorry. My bad.

Method 1:
First, I would suggest you to run the following Microsoft Fixit to get the problem automatically detected and fixed. This fixit checks if the device is currently disabled or turned off or the driver is not installed.
Hardware devices are not working or are not detected in Windows.
http://support.microsoft.com/mats/hardware_device_problems/en-us
Method 2:
Sometimes, some devices in device manager are hidden due to corrupt or missing drivers.
Follow the steps below to show hidden devices in the device manager and troubleshoot accordingly.
Press the Windows key + X
Select Command Prompt (Admin)
Type set devmgr_show_nonpresent_devices=1 and hit enter
Type Start DEVMGMT.MSC and hit enter.
Once in Device Manager hit the View menu and select show hidden devices.
From here, remove each instance of the Nvidia card you see as well as each unknown device. Exit Device Manager and reinstall the latest drivers you can find for your graphics card.
After you install the drivers, reboot and see if you get any different results.
Method 3:
If methods suggested above does not help, I would recommend you to contact ASUS to get chipset, BIOS, graphics card, drivers installed properly.
Also check with graphic card support site or refer the manual regarding the changes to make on the BIOS.
BIOS Disclaimer:Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly.
