Hello. My name is ***** ***** I will be assisting you today.
Technically yes. If the computer powers on, you could boot from a CD and access the hard drive.
If you had the right cable you could pull the hard drive and plug it into another PC like an external hard drive.
If you're talking about using a backup software program, then no the computer has to be working.
Hi Sir, What you can do is you can take your hard disk out and can take your back up in other hard disk if you are using desktop machine.
