Software Problem - ASUS bundled software

When I power ON the Notebook PC, there will be an “Open policy file error” message.

A.Reinstall the latest version “Power4 Gear” utility to solve your problem. It is available on the ASUS website.

Unknown Reason - Blue screen with white text

A blue screen with white text appears after system bootup.

1.Remove additional memory. If additional memory was installed after purchase, power OFF, remove the additional memory, and power ON to see if the problem is due to incompatible memory.

2.Un-install software applications. If you have installed software applications recently, they may not be compatible with your system.Try to un-install them in Windows Safe Mode.

3.Check your system for viruses.

4.Update the BIOS to the latest version with Easy Flash in Windows or AFLASH in DOS mode.These utilities and BIOS files can be downloaded from the ASUS website.

WARNING! Ensure your Notebook PC does not lose power during the BIOS flashing process.
