I have a Dell inspiron 7737. It is x64 and running windows 8.1. It boots up fine and runs fine. But at the BIOS screen (the one that pops up for 1-2 seconds) I can not access the BIOS menu, or select boot device settings. I have tried ALL Bios keys. (F2, f10, f12, del, TAB, ESC, Space, Enter) and still nothing. The text turns from grey to white when i push f12 (proving it is recognizing the key push) But then it just boots regularly.
