X51-R2 Driver Help?

I had just formatted my x51 recently, popped in the good old windows 7 cd, and installed it.
I started up the PC fine, and then proceeded to download the drivers for the parts and such again to make it work like how I first bought it.
To my surprise, after I downloaded the drivers that dell had saved for the x51 on their website, most didn't work for the system, and caused them to well, prevent the system to start after the windows logo.

The main problem is when I try to install the driver for the Intel Integrated Graphics for the i7. After installing it, and restarting to apply the changes, the system fails to start after the windows logo. Upon switching to the 670, it keeps prompting me to connect the PCIe cables, which I have already and come to the conclusion that the PCIe buses or the driver needs to be installed. 
What I'd like to know is:
Do I have to install the drivers in a certain order?
Which drivers do I ultimately need?
