Death Adder Elite and Black Widow - Synapse 2 Issues??

I understand this will be a difficult one to diagnose but I suspect it is a software/driver issue. But am open to opinions/solutions. I suspect these issues are related. Using death adder elite and black widow keyboard with synapse two on windows 7. Last night while playing a card game, my left mouse click key began to act erratically. It would ignore 90% of my clicks, but some would go through. There was no obvious onset of the problem. It was sudden and during the middle of a game. As I was testing the issue for the next 10 minutes, the left mouse click began to stop working entirely, but at the same time, my right click mouse key began acting as my left mouse clicker, with the left mouseclick not working at all. I was able to open synapse (with great difficulty) to check and see if the mouse settings had been changed somehow- they had not. I restarted the computer entirely, rechecked synapse, tried to update software but was informed it was up to date. Logged in and out of synapse. Now the left mouse was working maybe 50-70% of the time. Uninstalled synapse. Reinstalled and im around 90% of my left mouse clicks going through currently. But I am not getting full use of the left mouse clicker at this time to my obvious frustration. - Curiously, about a month or so ago, I noticed when I type, random keys will act as if I have pressed the key multiple times. Not a big deal really, i cleaned the keyboard by removing individual keys, no improvement or solution has been found (I had assumed it was synapse issue). - Curiously, some of my in game settings have changed in the games I am playing. This all coincided with the mouse behaving poorly last night. I have updated and run my antivirus software, no issues found.
