I have a brand new laptop as of a month ago. Asus S56A-BH51. It has been extremely slow since we got it, and have had lots of trouble with Windows 8. Now when I turn it on I get the same Reboot and select proper Boot Device that I have noticed is a problem on Asus apparently. Can anyone tell me in detail how to fix this? I am not a computer expert, so as much detail as you can give me would be greatly appreciated!
