Jerry Jose :
Your motherboard socket is LGA 775.
Can you mention the rest of you pc specs like ram(ddr2 or ddr3),proc,...etc to simplify the process..
As i mentioned i don't know much about the hardware, i know that ram is ddr2 and the graphics card is an asus EAH5450 Silent. The processor i have absolutely no clue, sorry for not making it easier :/
