The order in which the drivers must be installed is detailed here:

Also Video Controller,PCI Device

I already have some downloaded I do not know the order they were downloaded. Can I just start downloading again, in the right order

Do I need to start over

It would be better to do that, yes.

I did start over, but when I had some of the drivers in and I did put than in order I started getting a 150 error code and I don't know what that is or why. I thank you for help me out.   Jim

What is the exact text of the error message?

This is what it says " An error occured while unzipping, one or more files were not succesfully. The error codeis 150 "    Jim
