Well, I don't doubt what you say, but it is now common for manufacturers to point the finger at MS, as they are a big target. The fact that many of us are running Home on 64-bit Win7 without problems is not a matter of luck. Given Microsoft's early Vista fiasco, I have to believe they worked doubly hard to ensure hardware compliance with as many systems as they could test in the alpha and beta phases. Again, the best way to find out if you have a hardware issue is to try connect to another machine, preferably with the same OS. My system is homebuilt and I have yet to have a compatibility issue with Win7 on it.
