I have XP Professional, still at SP-1. I built my own pc last year and have had no problems so far. I have a microsoft intellimouse optical usb - it has the buttons on the sides. Recently, while using my computer, I hear the hardware disconnect tone and immediately the reconnect tone, and the optical light goes on and off - it's as if I am unplugging the mouse and putting it back in right away.
My first thought was that the usb port was going bad, but I have moved to a port in the front and it is still doing the same thing. I have drivers from the internet, and have not changed those drivers since I got the mouse. Now I am wondering if either my mouse or my motherboard is going bad. I would be surprised if the mouse was, because these things are typically pretty tough to break. I do game quite a bit so maybe that has had a bad impact on it. If it is the motherboard acting up, I would NOT be surprised - as I went with a cheap, generic provider when I built the pc - matsonic is the manufacturer.
Does anyone have any ideas? Also, could a virus / trojan cause this? I downloaded something that seemed suspicious the same day that this started happening, but I updated norton, ran a full scan, and it didn't find anything. Also have scanned with adaware up-to-date. No other hardware is doing this, just the mouse.
Thanks in advance.
