That's your computer's model number. For starters I wanted the model number for your CPU (AKA processor) to see if it's AMD-V enabled. You can find the CPU model number in Device Manager or you could try Bris's link.
I Googled your problem and found a couple of other users on the Acer community forum with the same problem. The advice was to update the BIOS to the latest version. Additionally you may need to "Load Default Settings" in the BIOS too.
The affected users didn't respond with any feedback but the advice given was sound.
