Black screen - res. Change, no boot screen

I adjusted my computers resolution (to a lower setting) and now I can not see anything. I tried waiting hopeing for the 25 second go back readjust thing. When I start my computer I do not see anything, no boot screens for windows or for the HP Symbol. I am very good with working with computers but I can not figure this out. I am running windows 7, 64 bit. All of the lights work like they normally would. I tried to pop out the system battery and waiting but still nothing. I also had a DVD in the drive that should boot (windows installation) and then I would hear the drive start to spin up loudly but I do not even here that like I normally do.

Thanks for any help!!
