I'm looking for a driver  

I have Dell Vostro 1700 and I recently upgraded to Windows 7 Ultimate x64. Since then some of my function keys are not working. Fn + F1 for example is supposed to put the computer to sleep but it's not doing anything. Can you tell me which driver should I install? On Dell.com for my computer there are drivers only for XP and Vista 32bit. For 1720 (which is the same series) there is for Vista x64 and 7 32 and 64bit. Maybe I could use some of its drivers? But I don't know which to install.
Other than that when I change the brightness of the screen of the volume i don't see visual notification as I used to in Vista. I think it is a program called dell quickset but I can't find it either.
I will appreciate your help. :)

So there's no quickset for Windows 7 64bit? I guess I'll just have to get over it.
In Dell's website my computer is shown as incompatible with Windows 7 But it's running fluently. Even though I liked my Vista i Love 7.
What about the function keys? Isn't there any solution?

The Vista driver should work. Just use the one that matches your version of Windows 7 (32 or 64 bit).

OK, I'll do that. But can you tell me which driver to download, because I don't know :)

Damned. Well thanks anyway

I found most of the Vostro 1700 drivers for Win7 x64 here:

Still looking for the touchpad drivers, though; I know they exist, I had them on a previous install of win7x64 on this machine (typing from my vostro 1700 right now).
