There are no drivers offered for download on this. The only way to get them would be to contact dynex's customer support. You shouldn't need any unless you're running windows 98 anyways.
Clicking in a harddrive is almost always a sign of complete harddrive failure. Which would a likely candidate as to why your laptop wouldn't boot.
Most likely the hard drive is toast, and it's the drive itself rather than the enclosure or drivers causing the problems. If you really insist on trying to make it work, or need files really badly off of it, try a 2.5 > 3.5" IDE converter such as this one http://www.newegg.com/Product/Produc...82E16812119020
that'll allow you to plug in the 2.5" laptop harddrive to your internal IDE cable. Frye's electronics sells em too.
Seriously though, I'll put money the drive is toasty.
