Network Controller and Intel HD Graphics Family not working on Dell Inspiron 660-4858

Hi,

I just bought a new Dell Inspiron 660-4858 containing Windows 7 Home Premium. Service tag-number JPYXD5J.
I installed Vista on it as I hate Windows 7. Now there are several drivers not working (when looking in device manager). I managed to solve most of them but there are still two I can not solve:

1. Network Controller. On Dell's website there are only drivers for W7 when looking up this device. According to the UKD ("UnknownDevices") software, the details for this device are:
Atheros Communications Inc
Dell Computer Corp
However, on Dell's website it appears to call the WLAN adapter (which I assume this 'network controller' is?) Dell DW1506 WLAN 802.11 b/g/n . Version of that driver is 9.2.0.484, A01, but it's only for Windows 7.
Any suggestions how I should find the latest driver for this device, for Vista??

2. Intel(R) HD Graphics Family (Dell's driver site calls it "Intel Graphics Controller" and "Intel UMA driver"). I actually did download drivers for this, supposedly for Vista. However, not thru Dell's site (they only have the driver for W7 and W8). But still there is an exclamation mark next to it in device manager.

I used Driver Genius Professional 11 to aquire alot of the drivers (some I had to look up manually). Is this software generally a good software of its kind, or are there better ones out there? Because alot of these driver recognition softwares have a tendency to download the wrong drivers and just mess things up further. Driver Genius Professional 11 appears to be the one that has done the best job for me so far, but I'm sure you know of better ways to find out where to get the latest drivers?

I'm still worried it might have installed the wrong drivers or not the latest versions for some of the devices. Any suggestions on how to find out the latest drivers for my computer very much appriciated!!

 

Sorry, forgot to mention: every time I turn the computer on, this message is displayed on the icon tray:
Incompatible display adapter has been disabled.
At least one display adapter on the system has been disabled because its driver is not compatible with the driver for the VGA adapter.

What exactly does this mean? Does it mean the actual screen is not compatible with the Intel HD Graphics driver or what? Because I am using an older flatscreen (VGA) temporarily (getting a new one soon).
Please explain what the error message means, because I am not sure.

 

please someone?? :-(

 

I wonder if you're ignoring my questions or just don't know anything.
