If you have a connection to the internet from the computer in which you need the driver the best method is to go to driver detective.
$29.95 for 1 year registration Driver Detective provides access to 27,000,000 device associated drivers including over 2,500,000 that are specific to computer manufacturers such as Dell, Toshiba, Gateway and Compaq.
$29.95 is well worth it.
For a 1 year subscription not only can you use it on your current pc, but any pc that you may be work on over the period of your 1 year subscription.
The site will save your registration key for you and a history with driver files for all downloads you use.
I have used driver detective on a approximately 30 computers of the past 12 months and I will never search or trust any other site again.
Final note; driver detective is not shareware, freeware, fakeware, or stupidware.
Check out the site before anyone else sends you to a file that makes your problem worse.
