Installing Windows XP Professional

Hello! I have been attempting to install Windows XP Professional on my PC. The PC is about 3 to 4 years old. I built it for myself. Hardware is as follows-> 900 Mhz AMD Processor, 256 MB of RAM. 20 GB Western Digital HD. Soyo motherboard K7-VTA (?) forget the model of the motherboard. When I put the Windows XP CD in and let it boot from CD. After copying files and just before I can set the partitions, in the gray at the bottom of the screen it reads "Start Windows." Then just sits there. I left it sit for about 3 hours one time and it did nothing. Wanted to know if anyone has ran into this issue? I followed some suggestions from Microsoft's TechNet articles and from the Knowledge Base and they recommend updating drive controllers drivers. I did that and still not having any luck. Maybe I am out of luck and will need to build a complete system all over again. Could someone let me know if there is hope.

Current OS on the PC is Windows 2000 SP3.

 

when it stalls you are supposed to turn it off by the power button
and then back on,and it is supposed to resume the installation.
if it does'nt i would try a low level format and then try the install again
