i have a normal hp mouse that doesnt require any software to use. it disconnects randomly from time to time as i play games and use windows. i tried my mouse on my friends computer for a few minutes it worked perfectly. i bought a new mouse from a shop and used it .... although the new mouse didnt disconnect it started to shiver on screen while i didnt even touch the mouse... please help me guys ... i ordered a razer abyssus thinking it was a problem with my mouse but i want to figure out wheather the fault is in my pc or the peripheral device
thank you soo much in advance for any help that u give me
