Forum Post: RE: Can I add extra memory to Dell Dimension 3000 or do I need to get a new hard drive

I suggest bypassing the Upgrade Advisor. The 3000 is definitely compatible with Windows 7, but the onboard video does not have a native driver and even if it did, it wouldn't support the 'Aero' user interface. 1gb is sufficient for either 32- or 64-bit.
