ET1810-03 Emachine

Hi all very new to messing around with bios but I currently have a computer that I would like to mess with the overclocking settings but I could not find the options to do it. So I am hoping some one here can help I have done a bit of research today about this.
I have already tried one bios that was a R01-A3 acer on this site that was supposed to unlock things but that file did not work out. So I have learned how to recover when things are done wrong...

Here is a link to the bios from the computer

If any additional specs are required let me know I can add to this post. From the base model there have been 2 changes done to the computer I have put 64bit windows 7 on there. On accident... It works ok if I have to undo that I can dig around for a 32bit windows 7 and even windows xp I am hoping I don't need to go back to xp for this.

The other thing I have added to this computer is the video card ATI
Radeon HD 4300/4500 series .

The rest of the computer though is the normal specs for a ET1810-03 Emachine.

Would greatly appreciate if any one can help me unlock this.
Once again if any thing else is needed I can provide some more information.

So it has been about a month just wondering if any one has any news if this can even be done?
