when the Bios logo comes up there will be a sentence that tells you what key to press, your already past that part. there should be a Bios manufacture screent hat comes up and t the end of the code it will say press (Key) to enter Setup. If the key that it says isnt working then your keyboard may not work maybe. if you could get into windows before try updating the bios. but if you got your computer from the store a long time ao looking at the board, then its most likely locked as most manufactures lock the bios to keep their systems fail proof. so no one will tangle with the structure of the computer and also lower on the rate of people sending them in for problems
