Stuck on BIOS screen

Hi,
I have recently purchased a custom desktop from a local store.
Whenever I start up the PC this screen appears:

The 'ASUS Republic Of Gamers' being in the center and below it says 'press DEL to enter UEFI BIOS settings'

It remains stuck on this screen and the keyboard is unresponsive even after waiting 20-30mins. I then reset the computer using the button and it starts up normally.
I have had to repeat this process whenever I want to use the computer and am getting worried it may damage the PC and be a major issue.

Specs:
OS: Windows 8 Pro 64bit
Motherboard: ASUS Maximus V Gene
Processor: Core i7 5770k
GPU: Gigabyte HD7870 OC version
RAM: Kingston 4gb DRR3 16000 (x4)

Is there any solution to this?

Thank you in advance,

Regards George P66
