E7400 (SLB9Y) does not support VT (Ref: http://processorfinder.intel.com/details.aspx?sSpec=SLB9Y)
Before buying a processor, always refer to this URL: http://processorfinder.intel.com/ for CPU details and it's supported features.
Now, as for Virtual PC 2007, it should run even if the CPU does not support VT, which is not the case for Hyper-V, Xen, VMWare or other virtualization solutions that require VT enabled CPU and Motherboad.
Can you kindly state the model of your motherboard you are using? Let us see how we can help you on this cause Virtual PC should work on this even if though it's not VT enabled.
Write back to us, thank you!

Thank you very much for your early reply.
My motherboard is 'ASUS P5KPL - AM IN / SI <GREEN>'
Serial No.: 94M0AD098183
Part No.: 90-MIB8I0-G0UAY0KZ
LGA775, Intel G31+ICH7, Intel Core2 CPU ready, FSB 1333, D-CH DDR2 800, 6-CH HD Audio, 8 USB 2.0, Crash free BIOS 3, 10 / 100M LAN, Q-Fan, Vista Basic.RoHS Compilant, SATA 3Gb/s
In my case I am facing exactly different issue, as Virtual PC 2007 is not running and VMWare is working properly.
And I informed the vendors also about incorrect information, hence they have corrected it.
Thanks a lot for your help.
