Freeze on boot

[B1Gtime]

Just built a new pc:
ASrock P67 Extreme4 Gen3 mobo
Core i5 2500k
2x4GB Ripjaws(1600)

When i start the pc, it freezes on boot menu(were u press like f11 and stuff) and will just stay like that. Then i found out if i unplug my mic and keyboard(usb) the pc starts back up after pressing the reset button. The board gives me a code 30 but havent found a succesful answer why this is happening.

Plz help=)

check that out, be sure to read the "how to update" thing, and if any more questions check forums, they often times have good answers, just google "update bios" and your mobo or something like that :)

You have to download it from the manufacturers website. Most of the ones I have seen are a .ISO file that you burn to a CD and boot from it.
