Your whole system is an agglomeration of parts, all made, and serviced, by different people; sometimes, but not always, used to dealing with different people. I can only help with my own example. I have a processor made by AMD.
I have a chipset and drivers, ethernet software,utilities, network connections, 1384 etc. made by Nvidia. Mt graphics card is ATi 9700 pro, made by Ati. My chosen o/s is Windows XP pro made by Microsoft.Now if one, or any of these don't function, or function badly, you step into a minefield of troubleshooting. I have only one remaining piece of advice, find out about your system in it's detail A.S.A.P. to save long term heartache and head scratching.
