Q: Strange intermittent problem with macbook pro

Hey there ppl,

So, i have a Macbook Pro (retina, 15 inch mid 2014), 2.2 GHz i7 processor, 16gb memory. Running OS X El Capitan.

My problem is a strange one because it only happens intermittently. Id say like 10-15% of the time. But its very frustrating and annoying when it does and because i work on my computer (poker) it is also costing me. Anyways, the problem usually arises after ive been using the computer for 1.5-3hours or so. Usually ill be playing poker online, listening to spotify, and using the internet for random stuff. Everything will be fine, then suddenly ill notice that my mouse cursor will suddenly shoot across the screen occasionally. like ill be going right with the cursor but itll jump to the left a couple inches or so. Also ill notice that some of my "clicks" wont register, so ill be using the calculator for instance and ill want to press 543, and maybe the 5 registers but then when i go to click the 4 it doesnt, and ill have to like wait for a sec and click again for it to register the click.

Additionally, if im typing something, like in poker i sometimes take note of the way an opponent played a hand or whatever, a letter or a spacebar press wont register, so ill be typing a sentence and the spacebar wont register and ill have to press it a couple times, and then a letter wont register, etc. Its very disorienting and makes it hard to continue on the task im doing because it doesnt run smoothly anymore because of the lags, non registers, mouse jumping, etc.

Im really unsure of whats the root of the problem and what it is. Ive run the malware bytes anti malware but that hasnt fixed the problem. Generally when this happens ill try restarting the computer, or shutting down and turning back on but usually the problem persists. Then, after some time, maybe 20-45 minutes or so, when i try using the computer it works totally normally with none of these problems.

Very bizzare. Any help or insight is much appreciated, let me know if you need any more information
