    Task Manager Performance not showing both CPUs


    I have a Dell Precision 690 with Dual Zenon 3.0 processors running Windows 8.1 Pro X86. CPU on the Performance tab only shows a single processor. I have the identical computer running Windows 7 Pro X64 and it Task Manager/Performance tab show2s two processors.

    I've read of other people having similar presidencies. Is there a fix for this?
