Rebuilt an old computer

[brandyk]

I have rebuilt an IBM Aptiva, place a new motherboard, power supply, video card and update to windows xp from 98 edition but now it is freezing up lately and Im not sure why? Also place a wireless card network card.
Any suggestions on how to fix it to run correctly? It has windows XP with service pack 2, ram of 512.

Track down and re-install your MBoard drivers...
Remove the Network card first then re-install it along with it's drivers as well.
Make sure to re-boot after each operation...
