Here is a link to the software and drivers for you computer. The bios updates are on this page. click here.
On start up, try holding down the escape key while hitting the F10 key to enter the bios. You could run MS Fix it to try and resolve issues click here. If you are still unable to enter the bios you can use the UEFI tool for diagnostics. click here. Please let me know how it turns out.
