1. I hope you are diligent about backups. Sounds like a hard drive failure or some virus or other infection.
2. Call ASUS and ask what they think. Windows 7 laptops only arrived recently and even that 3 month warranty unit is still in warranty.
Again, let's hope this is not another case where someone learns the backup lesson first hand.
