check if speedstep is disabled, if not just disable it(from BIOS).. check current CPU freq at system properties if its enabled you'll see that its running at far less than 2GHz.. enable VT-x in BIOS.
VT is enabled in the BIOS, however the HP BIOS does not give my many options to make changes, including speedstep. Currently I am running the latest system BIOS F.24 from HP. I can't remember now what BIOS (ex. Phoenix) I am running on this computer. If it requires a modded BIOS then I may need some assistance with that as well, as I have never used a modded BIOS before.
