Mouse Lag, and Screen Tearing

So im not sure on the etiquette on this but i have three issues.

my computer is brand new with good ventilation and clean environment. And i get near perfect scores in the system operations index check ( if that really means anything).

1) After start up when no programs are running i get a mouse lag for about 5 minutes. the mouse will move fine then it pauses every 3ish seconds.

2) I am getting some very bad screen tearing while playing video games. it recently started getting worse. i am no where near my RAM capacity and my graphics card can easily handle it. i can even see minor tearing on my home page with my 1280x920 HD background.

3) This is what might be causing issues but when i go into the error notification it has been giving warnings and errors on start up. the event ids that keep repeating with warnings and error are 100,101, and 200.

the game it happens the most is civ 5. also happens with games that use a lot darker lighting or thats when i notice it the most like MOH:Warfighter.

1) Is it a wireless mouse?
2) What driver version do you have for your video card?

no my mouse is wired its the razer taipan mouse with the latest update on that.

and as far as my video card. its the NVIDIA GeForce GTX 660. the driver version is 9.18.13.2049 when i search driver updates. and also in the geforce experience app it says version 320.49.

k thanks for the little trouble shooting tip. i believe i fixed the issue as of right now. i went and checked for updates on all my drivers and i my monitor was out of date. i updated the required driver. then i went onto the website for the driver installation and they gave me another update. the mouse didnt lag at all after start up and so far there is no tearing.
