I turned on my computer this morning and it freezes before the bios comes up.  It shows the Dell logo in the middle of the screen with the loading bar on the bottom, with the "setup" and "boot options" buttons on the right, but both of those buttons are grayed out and nothing happens when i press F2 or F12 respectively.  The loading bar stops moving about 3/4 of the way to full, and nothing will load.  There were 3 power outages yesterday, and my computer was turned on for one of them.  However, my computer worked fine earlier this morning as my mother used it without any abnormalities.  However, now when i try to start it up, it will not do anything at all, bios will not even load.  Only thing i can think of is the possibility that my USB drive was in the computer or that the power outages did something.  It seems strange though, as my computer is only about three months old and i treat it well, no viruses or anything.
