I think it might be the video card.
My system configuration:
AMD Duron 850
ABIT KT7A v1.3
Cooler Master DP5-6I31C
256 MB Kingston Sdram PC133 RAM
Inno3D Tornado Geforce2 MX/MX400
SMC Etherpower II 10/100 Ethernet Adapter
C-Media CMI8738/C3DX PCI Audio
Sony CDU5221 CDROM
I have to install the VIA service pack drivers before installing the video card driver.
Or I will get no display. (For 98 and 2000)
I will try to install Windows XP as soon as I backup my HD.
