My dad has a Athlon 900mhz, on a Gigabyte GA-7ZX mobo. He recently installed a pinnacle firewire and seems to be having a conflict somehow. An IRQ problem he was told maybe? Whatever that is? Anyways, when he tries to shut down his computer it just hangs and wont shut off. I think it even might start up again sometimes? Im not sure. Has anyone else had this problem or knows how to fix it?
