Hi my computer is a HP Pavilion a1310n. I ran CPU-Z and it says under mainboard:Manufacturer- ASUSTek Computer INC Model-Nodusm 3 1.05 Chipset-NVIDIA GEFORCE 6150 Rev-A2 Southbridge-NVIDIA 410/430 MCP LPCIO-SMSC I have an AMD Athlon 64 X2 4200+ cpu in my system. My question is is there any other CPU's available for my motherboard that I can upgrade to without a huge amout of extra hassle? I am playing Fable and it does not seem to like that I have a dual core processor much LOL!
