Double check the model aswell, anyways iirc most OEM pcs don't have bios flashing from the BIOS. Download the ulility from Acer and flash the bios.
If you get some sort of error, DO NOT SHUT OFF THE COMPUTER. Flash it until it works, if you shut it down when the BIOS is erased, i doubt there is any kind of bios recovery.

Tried this and I could update the BIOS but it didn't help with the Core problem. Still only one core.

Lol, I'll have to pass. I think mine can get up to 3.8 or even 4.0

Depend on revision, if it's c2 you cannot pass 3.8GHz (cos limit for c2 is 3.8GHz). Also 925 had more temperature headroom. Check this out -> http://www.overclock.net/t/1134229/amd-cpus-max-temps

It doesn't matter 925 or 955 if they both are c2 revision they both will hit 3.8GHz and 955 will run a lot more hotter than 925 also 955 will require better mobo because he had more TDP (125W) and 95W on 925. ^^ It's my offer.

Fire up CPU-Z and check revision. If it's c3 it can hit 4GHz but temps are the same 62'C and it becomes unstable after 55'C too bad. 925 gets unstable after 68'C. And when i hit 3.8GHz it never passes 53'C.
