I have an acer aspire m3100 desktop with an AMD athlon 64x2 (2.8GHz), 4GB ram, windows vista home premium, and so on. I purchased it from circuity city, and i was wondering what the chances are that a computer bought at the often resented electronics store has the socket am2 motherboard, the one where you can switch processors in and out. Or if someone could help me figure out if it is by looking for a certain label or something on the hardware itself--it's messy in there though. Any help would be appreciated!
