Ok. So a couple months back I had my cooler master hyper 212 evo installed... That's when I had my gtx 970. So I had my i5 4670k oc to 4.4ghz, and I was fine. For some reason though, Task Manager says it's at 5.3ghz.. But I didn't question it.. So about a month ago I got an asus 1070 strix III (or whatever the name is, im usually and MSI guy but I got asus) and I used the strix III app to oc the life out of my 1070.. I didn't have problems, until I used EVGA Precision X oc it instead, so I could oc more than the ASUS app would let me. I closed ASUS STRIX OC tool, and made sure it wasnt stil running by checking the process in Task manager, and For a couple hours my gaming was fine. Had like 60 degress on gpu. Then after like 4 hours it would say "oops your pc has shut down." blah blah blah. I tried turning it on, and i'd hear the gpu fans at max speed on bootup. Then that blue screen that said oops again. Then the next time it booted up, my gpu fans were silent which meant the oc was off. I had no problems till I oc it again with precision X... so I uninstalled it and then I used the ASUS app to oc it.. But then more crashes... which made no sense because it was fine before I got precision X.. It cant be a PSU problem because I havbe a corsair cx600 and the gtx 970 used more power... So what I DO remember is it took me 3 hours to install the cooler master hyper 212 evo and it almost fell out and I had the thermal paste constantly ebing removed... So maybe the air bubbles and blah blah might be the issues and maybe the cpu is overheating but I havent checked that.. Help pls because I dont want this 1070 dying on me thats my baby <3
