Hi there, I am in need of some help and I just can't figure this one out. For several years now I have been dealing with mouse problems. Double clicking and even clicks that don't register. My husband's and I's computer are on the same outlet for our computers. We both also use surge protectors. For some reason only my computer has ever had a double clicking problem. I've tried: a different surge protector, a different psu power cord, 3 different mice, constantly grounding myself, different USB ports (even my keyboard usb port), and leaving my mouse unplugged during the night. Not only that but my humidity is always between 50-70%. Nothing seems to be working at all! How can this happen to 3 different mice? Could it be my 8 year old psu is becoming faulty? This double clicking is very enraging and I really need some help.
