Update:
So i replaced the 1070 with the only other gpu i had on hand which was an rx 570 and the issue disappeared, but because the rx 570 is less power hungry than the 1070 i assumed i had narrowed down the issue to either the gpu itself or the psu. So i headed down to my local pc shop and we started by trying the closest gpu to the 1070 they had (a 1070ti) but the issue still remained. At this point we thought the issue was defo just the psu but after replacing the psu with a corsair cx 750 THE ISSUE STILL REMAINED. So far i have removed the gpu and power supply as possible hardware variables but i still haven't found the root of the issue. Could it be ram??? Then again why would using a less powerful gpu get rid of the issue ?!?
Idk what to do at this point any advice is greatly appreciated
