IRQs is located in the Hardware Resources category in System Information. It displays information about interrupt request (IRQ) channels on your system, and it indicates which devices are assigned to each channel and their status. The operating system allows you to use only certain IRQs. Other IRQs are reserved for a standard set of devices.
If there is a sharing conflict with an IRQ, such as a mouse not responding, use Device Manager to locate and troubleshoot the problem.
