problems installing win2000/winxp

i’ve tried to install win2000/winxp many times on my system. my system is:
GigaByte motherboard GA-FAX (nothing built-in), with
AMD K-6/2 500 Mhz ,
VGA : intel i740 8MB

windows install successfully but fails to run after first time, it hangs the system after its progress bar finishes.

i’m looking forward for a solution.
thanx
