"Hardware-assisted virtualization not enabled" Intel E8400, Opti 780 DT, Win 7 Pro 64-bit

I have a Dell Optiplex 780 Desktop with an Intel E8400 processor running Win 7 Pro SP1 64-bit, with 8GB RAM and a 750GB hard drive.

Wanted to try to use XP Mode for the first time and so checked the hardware with MS's havdetectiontool.exe.

It says "Hardware-assisted virtualization is not enabled on this computer". But both the Intel and Dell specs say I should have it.

In BIOS, I have ENABLED "Enable Intel Virtualization Technology" and "VT for Direct I/O". Following various posts, I have NOT enabled "Trusted Execution Technology". I got the error message with both BIOS A04 and now BIOS A15.

I have also ENABLED "Execute Disable Bit".

If I enable Trusted Execution, then havdetectiontool.exe gives me a different error message that hardware virtualization won't work with Trusted Execution turned on.

The Intel Processor ID Utility says "Intel Virtualization Technology: Yes"

 

"Intel VT-x with Extended Page Tables: No".

I also did a complete reboot with Shutdown - wait - remove AC cord - wait - press front button for a while - wait - AC back in - start up.

 

At all times, MS's havdetectiontool.exe continues to say "Hardware-assisted virtualization is not enabled on this computer".

So what to do?

Thanks.

I see that the http://ark.intel.com/products/33910/Intel-Core2-Duo-Processor-E8400-6M-Cache-3_00-GHz-1333-MHz-FSB Intel® Core 2 Duo Processor E8400 supports both Intel® VT-x and Intel® VT-d. So, I suggest updating the BIOS to the latest version or checking with the http://www.intel.com/support/oems.htm system manufacturer.

Did you, by any chance, try with different virtualization software?
