When I decided to buy a new pc My budget was Rs. 25000. Finally it ended in Rs. 42000 for the above mentioned config. I have installed Windows XP pro with sp2 in my new pc. I want to know the things that are to be done in my new PC to increase its performance. I have changed SATA I to SATA II. What are the other things that is to be done to increase the performance of my new machine ??? I have not upgraded any driver and BIOS. Is there any risk in upgraded driver and BIOS???
