Give driver check with Driver Booster:

It works perfectly unregistered,
the only thing is you need to manually install each needed driver.

download latest driver from the internet...search intel mother website..and install it..

you will need to find another video card that fits correctly OR modify the current video card so it fits, which voids the warranty and is not recommended.

Again, this is not a situation of a broken thing but stubborn resistance to search Intel and driver repository resources  (e.g.VersionTracker.) Is something wrong with http://support.intel.com/support/motherboards/desktop/D915GAV/ and the 'Latest Drivers' link there, http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=1673 ?   (Search for D915PGN if you need the drivers for that one instead., of course.)

Have you tried going using windows update ?

it may be able to find drivers you need.

I found the sound driver at
http://driverscollection.com/?H=Satellite%20L100%20%28PSLA0%29&By=Toshiba

In order to get the correct vga drivers you need to find out which graphics card it has. Intel/Nvidia/Ati

Laptop should have a sticker on top that says which it has

I checked out the specs on laptop and
It may be an intel gma 950

The vga driver can then be downloaded at any of the websites downloads/drivers section(s)
