When I got to the Device Manager>Processors in my old Windows 7 installation, all 6 cores of my CPU have ! Marks on them, and the Properties of each has this statement listed: "A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)" The drivers listed are all Microsoft signed and dated in a manner in which they appear to be native to Windows 7, and I do not remember ever attempting to install anything else. This problem has not occurred in the new W7 installation, so I'm guessing that there is nothing physically wrong with the CPU. Obviously the processors still work, or I wouldn't be able to boot to this system, but I'm wondering if this is the reason that the installation works much more sluggishly than the new installation? I have run Chkdsk and SFC, but neither report any problems at all, which it seems that they would if there was a problem with the installation. Running the automatic online update functions returns the result saying that the drivers are up to date. Anyone have any ideas of how to pursue this?
