Hi, I just installed a new XP pro SP2, but my ATI x1950 pro share the same IRQ as my build in Gigabit NIC card at IRQ 16. My previous operation system has both separated. I tried safe mode and delected both and let it redected but no help. I dont want to take another 2 hours to reinstall again. They could share, but I can tell by when I press the IE, screen turns black and the starting of windows before the login screen that my monitor couldn't detect any signals. Does anyone have ane trick on this or regedit? Thanks in advances.
