DX58SO - i7950 Processor - Issues with running Hyper -V

Hi,

I recently purchased a new Desktop PC. The details are as below:

Processor Type: Intel Core i7 CPU 950 @3.07GHz
Board: DX58SO Extreme Series

BIOS Version: SOX5810J.86A.5200.2010.0414.1420

OS: Windows 2008 R2.

I have isntalled Hyper-V and I have created a Virtual Machine. When I try to start the VM, it shows error that hypervisor service is not running.

I checking in BIOS setup, and I have enabled the below under security tab.

Intel VT: Enabled

Intel VT for Directed I/O (VT-d) : Enabled
Interrupt Remmaping: Enabled
FLR Capability: Enabled

But I still get the error that hypervisior is not running.

How can I sort out this issue. Help would be greatly appreciated.

Thank You.

Jay Chandran.
