unable to start computer

I bought an HP slimline Pavilion dual core running Vista a year and a half ago, and about six months ago, it started to give me error screens when I booted up. Here is a screenprint of the error screen. Now it is not booting up at all. Does this look like a hardware problem? This is the error that comes up on a blank screen after it sits for about 2 minutes and then beeps: AMIBIOS© 2009 American Megtrends, Inc.

When I reboot, the same thing happens. Any ideas?

Yes, it looks like your hard drive is bad or the hard drive has a loose power cable or SATA cable. Either way, the drive is not recognized. Its probably a seagate barracuda.

Thanks, do you think it could have been done by a virus? I got a computer virus around the same time this started happening, but someone on this forum helped me fix it.
