Hardware virtualization BLOCKED - BIOS or motherboard problem from Dell ????

Hello experts - hope you all had a great and tasty Thanksgiving - but this one is a doozy:

I have a new Dell Optiplex 7010 MT with with 8GB RAM, a 500GB hard drive and an Intel Core i5-3470 CPU @ 3.20GHz – this is a genuine quad core processor with hardware virtualization. I am dual booting Win 7 Pro 64-bit and Win 8 Pro 64-bit.

Also, I have BIOS A16 with the following settings:
Virtualization Support:
Virtualization – Enable Intel Virtualization Technology is ON
VT for Direct I/O is Enabled – ON
Trusted Execution is OFF

HOWEVER, in Win 7 Pro, I am getting ready to do XP Mode but when I first run the havdetectiontool.exe from Microsoft, it says “Hardware-assisted virtualization is not enabled on this computer”.

Hardware virtualization should be working but something is blocking it – and it’s some type of weird BIOS - hardware problem.

The MS havdetectiontool can create a detailed report - and I am pasting it below. BUT I HAVE ALREADY POWERED DOWN AND UP THE MACHINE MANY TIMES WITH THE ABOVE BIOS SETTINGS. Something is wrong. What is it?

This is the full report:

►SO WHAT TO DO ?? Hey, Dell, did you make a dumb mistake in the BIOS?

►MORE INFO:

I ran an odd test from Intel called BITS, and it showed an error in the MP Table and two errors in MSR. Don't know what that means, except that "MSR" shows in the "havdetectiontool" results I posted above.

Also, I strictly followed AGAIN the instructions above in the havdetectiontool test -

1) changed the BIOS to DISABLE the two virtualization options, did a complete power down, waited, pulled out AC plug, waited, pushed power button to discharge the capacitor, waited, connected the AC cord, waited, powered up, ran the havdetectiontool test, got the same results.

2) changed the BIOS to ENABLE the two virtualization features AND the Trusted Execution feature, did all the same power down and back up recycling and got an immediate boot error: "Alert! Invalid Trusted Execution Technology Configuration. Please refer to the Trusted Execution Technology Setup option helptext for details." But I have no idea where that helptext is. In any case, it is EXPECTED that Trusted Execution not work. But surprised it prevented boot-up.

3) Went back into BIOS, turned OFF Trusted Execution, left ON the other two virtualization options (so I'm back where I started), did the whole power off wait AC out power on again, booted OK, but same “Hardware-assisted virtualization is not enabled on this computer” message from the MS havdetectiontool test - back where I started.

Big pain in place where I sit on Michael Dell's nose.

Are you awake after reading this exciting saga? Any ideas?

► MORE INFO:

The Optiplex 7010 is dual-boot. At the moment (for this update), I'm in my Win 8 Pro 64-bit OS. Its "System Information" shows the following four lines:

Hyper-V - VM Monitor Mode Extensions ... Yes
Hyper-V - Second Level Address Translation Extensions ... Yes
Hyper-V - Virtualization Enabled in Firmware ... Yes
Hyper-V - Data Execution Prevention ... Yes.

I am not familiar with Hyper-V, and I certainly didn't install it on my own. I don't know why there are any references to it. But, anyway, do these four lines mean anything?

Does the machine's DEP prevent the use of hardware virtualization?
