HELP! My optical mouse has been locking up of late where a beep sound comes from the motherboard and my optical would lock up for a few seconds, the laser also goes out. This also happens without the beep. My keyboard works fine when this happens. I've tried everything, switching from ps/2 mouse port to usb did not help. Tried other optical mouses and the problem still occurs. Tried other things in the usb slot where the mouse was and no problem there. Downloaded the lastest mouse drivers did not work. However, I switched to a regular ball mouse and no problem. Is it my power supply can't handle an optical anymore, or something wrong with my windows or is it my motherboard. My system is a 2.4 P4, 512 DDR, running windows XP professional. Please any help is appreciated as I am sick of using a crappy ball mouse. Thank you.
