Can anyone help with this problem i have it`s driving me nuts !!!!!! . When i turn on my pc my optical mouse LED light is on ok as pc boots up but as soon as the page windows is now starting comes on it goes off and is un-useable , i get the same result wether it`s plugged in the ps2 port or usb , i`ve tried uninstalling the mouse , usb drivers and my modem , because if i unplug the modem from the back of my pc the mouse lights up instantly . All the things i`ve tried don`t work another puzzling thing is if i leave the mouse alone for about 30 mins on average it then starts to work as the light on the mouse starts to flicker then burst into life , once this happens it works fine all the time until i next turn the pc on . I hope someone can offer me something new to try as it`s really P***ing me off now , many thanks in advance .
