Okay, so i bought a mouse from china and i got it 2 days ago. It was working great until yesterday, it stopped working but the light was still on, but the LED light for the DPI was off. I tryed to reconnect, update drivers etc but it didn't work. The only time it works is when i restart my computer. then it turns off after about 5 minutes. I have tryed it on all other computers in my house (6) and it does the same thing. Please help, thanks.
