Don't know about that old processor, but you already under the minimum memory requirement of 4GB, 2GB is already too low for a Win 7 box. Can't say much about the video card as there are at least 6 different versions of that card with various bus interfaces from PCI Express 2.0 x16 down to PCI.
Maybe you could try testing the system here. From what I can tell it might set off your virus scanner if it's prone to false positives (at least that's the reports I see on various forums).
