Have you tested your memory on box #1? all it takes is a bad bit in a range that normally isn't addressed unless you have something like a graphics program loaded, and boom. There could also be issues with the CDDVD drive that you used to load the program. Older ones could easily have firmware issues, or simply not enough buffer, to load a stable install. And Vue has run like a champ for me on A Gigabyte Triton K7, the new K8-VNXP for the Athlon 64, A Chaintech ECS board, A couple of different ABit early Athlon boards (Thunderbird core support). Memory from PC-3200 to PC-2700 to PC-2100 to PC 133 (except for a couple sticks of Corsair, it's all been Kingston ValueRam). This could also be a chipset driver related. There is an order that drivers need to be installed in....only problem is, the order changes constantly.
