I just recently got an asrock 970 extreme3 mobo. I installed everything and made sure to take off the cmos cap. Then when i try to boot it up, i get nothing. The hdd light blinks for a few seconds then stops, my disc drive opens and closes, all the fan spins up. The keyboard caps lock light isnt working though...

Specs

ati 5770(no onboard video on this mobo)
amd phenom ii x6 2.8ghz
sata hard drive
usb keyboard and mouse
and what else do you guys want to know?

My old mobo is a gigabyte m68t something something..
