I have an Acer Aspire 6360S. It has a celeron 500mhz and the motherboard chipset is an SiS 620. I want to put a new hard drive in this computer an install a new version of windows xp. The disk that originally came with the computer is scratched up beyond use. I went to driverguide.com and found the drivers that I think I need. However, I'm not really sure what drivers I do need, and when I get them I don't know what to do with them. Also, is it possible to upgrade this system to a pentium III? It is a socket 370 motherboard. The number on the motherboard is v76m. Any help would be greatly appreciated.
