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.
