Booting Problem

I have a computer that has been working fine (last time 11/11/03) but is now not booting. When the system is powered up, it starts the boot sequence fine but them it gives an error message “searching for boot file from SCSI..not found”. My system is using a IDE drive and there have been no new hardware or software installations.

I am running McAfee Virus Scan online and a trojan was found and deleted; however, I am unsure if this had anything to do with the problems I am getting now. When I powered up the system, I tried to boot into safe mode so I can boot using the last known good configuration but nothing. Also the disk is not registering.

I have concluded that the hard drive has crashed but I was wondering if anyone has anything else I might try.

HELP!
