Hi, I recently bought a new computer system with the Asus P4S333C M/B and am using XP (home). I did a clean install but I have an IRQ sharing device conflit. This conflict is between Memory Stick Device Driver A and Secure Digital Device Driver B trying to share the same IRQ - #5. I have no idea what this is or what these devices do, but the drivers came with the m/board. So far, I have not been able to work this out. I can't seem to find a solution, other than disabling these devices. They don't seem to be causing any problems with my system and when enabled, the "!" icon appears next to them. Can someone please help. I am just wondering if someone out there has had a similar problem. Thanks in advance.
