Since its a new laptop contact ASUStek Support, check their on-line documentation and drivers, and
ask in their forums about known issues. Support may have fixes for any known issues and you would
want the issues documented in case they continue or there are down the road complications. Look
at ASUStek for updates to BIOS, low level chipset drivers, and other on-board device drivers.

Vista and Windows 7 love updated drivers so here is how to update the major ones.
This is my generic how to for proper driver updates :
This utility makes it easy to see which versions are loaded :
DriverView - Free - utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
description, version, product name, company that created the driver, and more.
http://www.nirsoft.net/utils/driverview.html
For Drivers check System Maker as fallbacks and Device Maker's which are the most current.
Control Panel - Device Manager - Display Adapter - write down the make and complete model
of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate
Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -
Uninstall - REBOOT this will refresh the driver stack.
Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party
with their own software and drivers and any other major device drivers you have.
Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device
Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for
BIOS, Chipset and software updates at System Maker's site while there.)
Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after
each installation.
Always check in Device Manager - Drivers tab to be sure the version you are installing actually
shows up. This is because some drivers rollback before the latest is installed (sound drivers
particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as
needed.
Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check
manually by model.
Manually look at manufacturer's sites for drivers - and Device Maker's sites.

If you update drivers manually then it is a good idea to disable Driver Installations in Windows
Updates, this leaves Windows Updates ON however it will not install drivers which will usually be
older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then
