Welcome to TF!
put the hard drive in a plastic bag and into the freezer for about 2 hours. install it and try to run it. If it works, back up everything you want. then get you a new drive and reload your OS. If not then...
assuming you have all the disks and drivers. if not then you might be able to look at the companies website and download the drivers needed, (I.E. - Chipset, audio, video, LAN/wireless, etc...) specific for your laptop.
you must have the OS disk first though. If not, then this won't work.
