Bios Problems Very Wierd

[SplicedLife07]

Hello,
I have just run into an issue I seem to have never even heard of or can find information about.
I cant enter my bios my computer runs perfectly fine all system checks via boot integrated software, personal Cd programs, and O.S. software checks turn up A OK! but i cant get in to the bios it just boots to the O.S. I can select the boot options menu :
(DVD drive, USB drive, HDD drive, Systems Diagnostics, <Enter Setup>(also doesn't allow any access to it))
So if anyone could help that would be greatly appreciated.
My system is a Dell xps studio 7100 Bios Version A06 (newest version) running Win 7 64bit Ultimate

What are you doing to access the BIOS? What key?

At boot I'm pressing F2 (which is what it says to) there is also F12 for boot options which i also tried

I think F2 is what the manual says. Some times it's just a timimng issue (pressing too soon or late). Are you pressing the F2 when the logo appears?
