Good day! I want to upgrade my old pentium II, 128MB PC133 SDRAM & 40GB HDD PC by changing with a pentium III capable motherboard. I want to change the motherboard only and utilize the existing memory card & HDD. What are the procedures (step by step) in doing the change? What will I do to my HDD files. I can do a clean HDD installation but how to for an HDD with existing files is beyond my little pc knowledge. Anybody to help me? Thank you.
