Question about my Acer desktop's motherboard

According to this website:

http://www.compusa.com/applications/searchtools/item-de...

it is in fact a AM2+. That doesn't mean that it will be easy to upgrade. First off according to Acer, your computer only has a 250W supply. The other thing is whether or not your BIOS will support more than a 6400+. If that's the case, the 6400+ is not much of an upgrade and as far as I know all 6400+s are 90nm where as your 5600+ is a 65nm CPU. Since it's an OEM box, overclocking is out. So many sticky questions when it comes to upgrading on OEM boxes. I couldn't find any information on upgrading with regards m3100.

Sorry I couldn't be more help.

i want my cpu`s motherboard to be updated or activated......properly  

Hello - I am a new guy here, I realize this thread is a couple years old, but it is very similar to my situation. I have an Acer M3100 from Circut City. Recently I took it to Computer Deli and was told the mobo is bad.

Would any of you recommend I just buy an exact model mobo like this http://www.serversupply.com/MOTHERBOARD/DESKTOP%20BOARD..., or could I just buy a cheapo and save some bucks since its a 4 year old desktop? I've seen some under $50.

I plan on using it mainly for web, light business use.

Thank you in advance for your help, and what a privilege it is to have this site as a resource!
