My computer is stuck in BIOS and doesn't boot into Windows XP.

My computer is stuck in BIOS and doesn't boot into Windows XP.

I built a computer back in the year 2000. It work just fine then. I set it away for a couple of years, but now it just shows a screen of system information. the keyboard freezes when plugged into all USB and PS/2 ports. I figured it is the hard drive that either failed or is frozen or just some how wiped all my data? Please help.
