Hi everyone, This past month my Mac G4 700 tends to lose it's USB signal and I have to keep removing and then plugging the USB back. It's a hassle when my mouse or keyboard dies, then having to keep that routine going. I usually have my computer on 24/7, never shut it down, I put it on sleep mode when I'm not doing anything but was wondering if anyone has had this problem or no what can cause my USB devices to keep shutting off (is it power supply, memory or processor related)? - daa
