Best to take it down to 2gb RAM for install if possible.

Can you default to onboard graphics chip in BIOS or physically uninstall or change the Video card?

If not, try uninstalling just the display driver in Device Manager accessed this way during install: Device Manager - Access During Windows 7 Installation

What other drivers are showing in error, and which are in error because of no driver or failure to start device?
gregrocker gave you that advice a week ago.
