What I want you to do is:

Right-click on "My Computer"
Go to "Properties"
Click the "Hardware" tab
Click "Device Manager"
Click the + next to "Display Adaptors"
Tell me what it says there
Right-click on the entry in the list
Choose "Properties"
Go to the "Resources" tab
Tell me everything next to a "Memory Range" category in the resources list.

Also, you might have better luck if you dropped all your graphics settings to minimum.
