Model of Dell and Operating system did you clean install?

It is the Inspiron 15 3521

With windows 7 premium

I am not sure what install was done. I imagine it was a clean install. My business partner's brother who is

out tek geek did the install for us. 

Thanks for the help

The drivers and downloads page is quite buggy. Use the Dell ftp website instead:

Unfortunately Dell do not list the drivers in the correct install order, something we've mentioned should be done on several occasions.

Have a look at my Windows Reinstallation Guide/A Clean Install of Windows 7 Step 5 and 10:

This provides more information about downloading and installing the drivers in the correct order.

Thanks for the help. I really appreciated it.

So, basically I have to download all those drivers? 

Why can't Dell just make a file that does so in order?

In today's world this is just so silly. No wonder they are a failing business.

The problem is that you manually installed the Operating System. Dell generally have people use recovery partitions these days which have all the drivers loaded (aswell as some potentially unwanted third party software). They also include a means to make a recovery USB. However if an OS has been manually installed then the factory recovery partition is gone and the factory settings can only be recovered with the USB if it was made when shipped with the system.

There are some features on the Drivers and Downloads page which should allow one to download multiple drivers to a .iso file but as mentioned Drivers and Downloads is sometimes a bit problematic and you would have to manually install all the drivers in the same manner anyway.

All the drivers are on the Dell FTP, for Windows 7 64 Bit, Windows 8 64 Bit and Windows 8.1 64 Bit:

You need only the Windows 7 drivers. There are also some variants on this system namely the wireless card and graphics card. You have to pick the correct variant, inputting the service tag on drivers and downloads used to bring up only the correct driver set associated with that unit however in my experience over the last year or so it has been a bit problematic. I usually identify the variants using hardware IDs. See Windows Reinstallation Guide/A Clean Install of Windows 7 Step 12 and post the hardware IDs under "display adapters" and "network adapters":

The hardware IDs can be used to identify the graphics card and display adapter.
