Dell Vostro V13

I got an answer on my first question regarding en new disk for my system but I have some question as I already tried and installed windows 7, but as the system is not reacting like it did before the crash. I think I'm missing some drivers. Of course I installed the drivers form the Dell site.

So what am I missing. Checking my disk I miss a partition that was on the original disk with probably the restore info.

What I did is installed Windows 7 form a bootable usb stick and after that installed all required drivers.

Please advise.
