Vista Dell Studio black screen froze can't start in safe mode

Turn computer on, it only gets to the black screen w dell on it and lower right corner shows f2 set up and f12 boot options but those don't work,will not start up n safe mode
 
Were there any symptoms/problems prior to this?
Remove the battery. Hold the power button down for 30 seconds. Try to boot with and without the battery.
If F2 and F12 don't work you have a serious problem,
Have you tried booting from a CD/DVD?
