I can't get into the BIOS or boot menu

I just tried it several times F2, F8, F12
and nothing works,. just skips over them
and goes directly to MBR.

As I said I've done this before on the 8500
and F8 and F12 should work just like the 780
which does work.

In passing, I tried the Kapersky CD again since
everything came up clean with the bitdefender and
I deleted all the malwarebytes threats but got the
same results as before.

I looked up possible solutions and they suggested
updating and if that doesn't work to rollback to a
earlier version and then update which is what we did.
