    I have recently added a cordless rechargeable Logitech mouse to my computer, It seems to have created a usb conflict with my Radeon 9000 vid card. now the system is less stable on my online game (everquest) and causes the system to crash in graphic intensive areas. Any help on how to resolve this conflict would be greatly appreciated.

    Thanks

    AFAIK there is not a lot you can do about IRQ or other resource conflicts under modern PCs. Does it actual show a conflict in device manager? if not then it is just a case that the resources are shared, which should be fine in theory.

    If you want to free up more IRQs you could try disabling some unnessecary devices such as the Parallel and Serial Ports, in the BIOS if you don't use them.

    Additionally, try moving the mouse to a different USB port if possible, on most new motherboards they have at least 4 ports, of which 2 are on one USB controller, and 2 on another.
