You have to tap F8 or F12 repeatedly during the Dell logo screen.

 

I suggest F8 and select   last known good config that worked.

Are you able to access the BIOS? If yes, run the diagnostics program in the utility partition?

 

Does your sytem have a PCI video card, or are you using the onboard integrated video controller?

 

I believe that I did try to run the diagnostics in the the utility partition, it would not let me. I will try it again and post what it says.

 

Also, I am using the onboard video card.

I have tapped, held, etc the F8 key, I get to the screen but it does not complete any of the options it just goes right to the BSOD.
