i7 6700k lag problems

[sunnypsidup]

so i just upgraded my pc's processor from a old fx 8320 to the new i7 6700k i've downloaded all of the drivers for the motherboard, cpu and my gtx 980 drivers are also updated but im having trouble playing games. i have crazy frame lost and its stutters when i move my mouse, even just watching a youtube video on one of my monitors makes the video lose frames if i move my mouse back and forth rapidly. i mostly play league of legends which isn't a demanding game at all so i shouldn't be having these problems i also checked Ark,  csgo, life is strange, tomb raider and and they all have the same problem 

 

 i ran intel's processors diagnostic tool  and it had my cpu under 99% load and here is the interesting part  the game started running completely fine no stuttering no frames dips below 100, as long as the cpu was under full load the game didn't stutter or lose frames and i have no clue how to fix the problem please help

What motherboard are you using and what is the cpu running at in mhz?

Problem with switching an OS between two setups are the drivers. Changing a drive isn't a big deal but changing the architecture has drastic implications.

im using a msi z170a m5 and i haven't overclocked the cpu or anything its running at 4.0 right now

From what I understand when Windows installs, it uses information from your motherboard, CPU, things like that to optimize itself. Last time I did a motherboard swap a reinstall was needed because Windows wasn't very happy with what I did, and decided not to allow it to boot from my OS drive. Do a backup and when you can do a reinstall, that's your best bet.

okay last resort it is lol  i guess i'll go buy another flashdrive and try the fresh windows install tomorrow i hope that fixes the issue
