Recently built my first PC, all new parts, made sure to check every single component over making sure the wiring was all good and been using it for about a week now. It runs really well and games run pretty good aswell. Apart from when the GPU usage randomly drops to 0% and my games stutter. It isn't as bad in Modern Warfare but on Rainbow Six SIege it is really bad. Can play for about 30-40 minutes and then it will start stuttering every 5 seconds. Radeon software shows that it is dropping GPU usage to 0 during the stutters. Also all drivers are up to date and I have tried the recommended and optional Radeon drivers but the issue still persists. DDU hasn't helped either. DXdiag file is attached.
If any other info is needed just ask. I will get a screenshot of the GPU usage drops when I see it again. (i know i should have come prepared, my bad).
Help is appreciated
