Hi
When trying to boot my computer it comes up with searching for device at hba 0, id 0, lun 0 and gets stuck there or, rarely, continues booting after about 30 seconds and runs fine.
the problem only started yesterday after the computer crashed and i had to shut it down by holding down the button at the front of the computer

My OS is vista
The computer Model is a dell 650
I don't know how to find out the names of the hard disks at the moment
