Ok how do i find out the answer to the 1st question?
The MB has integrated graphics + you have an add on video card in the ATI RV100, which device is your display connected to and if the ATI device have you reinstalled the drivers for it (they will be old and possibly hard to find online).
As an asides saraveza408 can I ask if before you had Windows 7 installed did you run the Windows 7 upgrade advisor tool. first.
And no,i did not run the advisor tool
