Greetings to you Vonmpinnk,

You can enter the BIOS by pressing the F2 key, just as you power up and while you see the Dell splash screen displayed. To reset the defaults, simply press alt+F once inside the BIOS. Once done, hit the ESC key then save the changes.

Make sure and backup any data on the hard drive before making any changes in the BIOS. Just in case.
