Hi,
I am going to try to help you.
This is going to be a tough one as far as an install.
Do you have Vista still on this PC?
If so I want you to download and install
EVEREST. Scroll to the bottom of the page.
Once installed run the program. It will produce a report that will tell me what you have for Hardware. Post the report to the thread.
As far as your SATA driver it is part of the Chipset driver Nvidia Geforce7100/nForce 630i. I will tell you how to install this, but I want to see the report first.
Thanks,
Bill
