in the last several months my mouse has acted strange. not registering click and such. I' ve tried 3 mice, wired and not. checked all drivers. same on all games. finally decided it must be my old {5 years} motherboard. so I up graded everything but the graphics card to the newest stuff. still happening. I am using a Fnatic mouse. do yoou think it may be the graphics card (invidea 970}? seems odd.
