I’ve been having a problem with my mouse since last fall, and it’s getting worse. When I left-click on the mouse, about a third of the time it does what it’s supposed to. Occasionally, it does nothing. Mostly, though, it does a double-click, and sometimes a triple-click.
The computer is a 4-5-year old Gateway running Windows 7 64-bitwith 8GB RAM and dual Intel Core i5-2320 CPUs @3.00Hz.
The mouse is wireless, so my first thought was that the batteries were going dead. Replacing them didn’t help. I switched to a spare wired mouse that I had lying around; same problem. I have tried both mice on pretty much every USB port I have. I have uninstalled the mouse drivers and rebooted to force a re-install.
I tried running sfc –scannow; it showed no problems.
Everything else I use in my USB ports works with no problems: keyboard, flash drives, MP3 player, smart phone, tablet, etc.
Does anybody have any idea what could cause this, and/or what I can do about it (short of buying a new computer)? I’ve even considered upgrading to Windows 10 to see if that solves the problem, but would be a last resort.
PS. Here's another issue that I forgot to include above: when I have managed to click and hold on something to drag it somewhere else, it will often release the object without me moving my finger off the mouse button. Or if I try to click and drag something, the actual click might not happen until after I've started moving the mouse, and I end up dragging something other than my intended target.

It could be that it is the USB ports on the motherboard. We had a similar problem with a particular set of Dells at work. I put in multi-port add-on USB cards in them and problem was solved. the cards were only a few bucks each.
