Machine has all it takes but still cannot load 64 bit guests

Hello,

I have been looking for a solution for hours about enabling VT-x support and I just can't make it work.

My processos is a Quad Core 64 Bits, my BIOS has VT-x support, it's enabled in Bios, Trusted computing is enabled in Bios, my host is a 64 bit Ubuntu (11.10 Oneiric Ocelot), I checked that the processor has the vmx flag in proc/cpuinfo, I am using the latest Virtualbox version (4.1.4 r74291) the virtual machine was created as Ubuntu 64 bits and still it shows the message that it can't detect a 64bit cpu.

Is there anything else I can do about it ?

Thnx
-Nelson

What is the exact PC brand and model number? Exact CPU type?

Solved it. Disabed TXT in Bios.
One thing to notice is that these Bios options were only recognized after a power down of the computer. I have tried to only change and restart and didn't work. After I switched off the computer and back on, it worked.

Bios Options:
TXT: Disabled
Trusted Computing: Disabled
VT-x: Enabled.
