So i got this Silvertec mouse (wired optical mouse) and i used it on my old sony vaio laptop . Just last night when i was about to play a game , all of a sudden it wouldn't work . It lights up on the bottom but when i move it or click it , it doesn't work . I've tried to look it up on my device manager if it's driver was there and the only thing that was there was the touch pad driver which was the "ps/2 compatible mouse" . I tried to look for solutions online but nothing worked . Can anyone help me?
