I have an old AMD Sempron processor 3200+ and i bought this computer as a whole package about 1-2 years ago, i was wondering if i could buy a better AMD processor like an Phenom and replace my Sempron processor. What i want to know is if it would work on this computer, i do not know what kind of motherboard i have but i know it supports AMD processors and i have a PCI express graphics card. If anyone could give me any extra information about finding how to find what kind of motherboard i have would be useful aswell.
