PC/Games are suddenly crashing

[Zic]

ok so my PC has been running fine for the last few weeks (one day it had a weird screen that looked like this https://goo.gl/images/8OD1qj exept the lines were vertical and on the same day windows restarted and fixed it) now after following this OC guild (https://rog.asus.com/forum/showthread.php?86398-Strix-GTX-1070-Overclocking-Guide) and now my PC cant even run CSGO which is CPU intensive i have the 6700k with a kraken x52 nor rainbow 6 seige or witcher 3 and when i played rainbow eariler today every two secounds the screen and audio stopped for a split secound than went back to normal and i was wondering if i freid my GPU with to much voltage even though pascle chips have regulators (here are two threads asking bout this https://tinyurl.com/lfxul6z and https://tinyurl.com/m4febve) i know its not bottlenecking because i have the 6700k and a 650 watt 80+ titanium PSU with 16gb DDR4 3000mhz and when playing these games only the GPU was overclocked. so i think i brunt my GPU but i want to know what you guys thought (i downloaded the lastest drivers today for the GPU) oh and one more thing that might be affecting it is that today i downloaded the software that comes with my motherboard (ASUS Z270-H) like ROG game frist,IV, ROG ram cache, ROG cpu-z and GPU-z and maybe that was slowing it down, turned off malwarebytes but not avast, at first my GPU could run heavan benchmark no problem now it cant even run it for two secounds and my CPU was not overclocked during any of this so its probably obvious by now but i think i did something to my GPU and if i did how do i do a hard reset or reset windows without losing files and if there is what will it reset

Thanks

I figured it out all I did was lower the OC and it worked
