Driver Toshiba Qosmio G45-AV680 and Qosmio G45-AV690 For Windows Windows XP and Windows Vista.  Driver for Qosmio G45 available 48 items.  Link for downloading in the bottom of this post.  I don’t collect one by one of the link but I put global link that listed of the drivers, So I don’t mention all of the items. Some of Qosmio Series have the same hardware if you difficult to find the specific driver, you maybe try other Qosmio drivers type.  If there is more one type I only pick one type link for downloading.

Driver for:

* BIOS
* Video Card / Sound Card
* Modem
* LAN / Wi-Fi / Bluetooth
* Finger Print
* Utility
* Chipset
* Security
* SDCard
* And More Driver

If drivers not work you can use this link to get specific driver http://www.csd.toshiba.com/cgi-bin/tais/su/su_sc_modSel.jsp  but I think there is not much different because most of its have the same hardware.
