Your motherboard size is called "MICRO-ATX" and you CPU socket model is "LGA775". So any "Micro-ATX LGA775" motherboard will work (Assuming your CPU and other components are still good).

Here are some motherboards I found online:


My personal opinion, I would recommend buying a new computer. Your machine is 8 years old now. A lot has changed since. I don't think you will regret this decision :)

Best of luck!
