So I just got a new computer from my local computer store. I was able to test the computer out at the store and verify the specs etc. So I buy the computer and take it home and when I boot it up it brings me to the BIOS splash screen. So I can press del in order to get into the menu and there is a lost of other keys I can press. Well the problem is my keyboard wont let me select anything. My keyboard lights up but none of the keys work and when I hit escape or space bar the lights just shut off for about 15 seconds then just like cycle like they are on display.. I am so confused because everything was working at the shop now I can't get passed the bio's screen. I am using the USB 2 port in the front of the computer and have tried using multiple ports The mobo is ASUS P7H55-M Pro.
