Chosen Solution
When trying to boot to the OS, I get an error 0xc000021a and the PC continuously tries to reboot. If I press F2, I get a dialog box with Password/Unlock Key and the code 11DAA97B. I am trying to get it to boot to CD so I can re-install Windows. I tried entering a code from http://bios-pw.org, but it did not work. Hopefully, somebody can help with this issue.
On the Acer Aspire V5 series, if you open the bottom cover and remove the RAM you should find a couple of pads on the board labelled G2201. Remove the battery and power cord from your machine. Use a piece of wire to short those two pads. While holding the wire, plug the machine back in, then hit the power button. This should clear the password. I had to do this a number of times, but what finally worked was to hold the power button down while the machine came on, then shut off. I cycled this a few times then eventually the password was removed and I was able to get into the BIOS setting screens. Good luck!

The solution suggested by Tom Stephenson above worked for me, I was using a wire from an audio cable which wasn’t working for me at all, I guess because it has too many little fibre cores. I then tried using a wire from an ethernet cable cut out a coloured piece snip both ends and place each end on the G2201 copper triangle pads. Worked first time hold the wires in place then press the power button and hold.
