I have newly assembled my PC. All parts are new except for the reused old GPU. Booted up and installed Windows without any issue. System is stable except for random freezes a few times a day. It happens often whenever I played a video or played a youtube video. I downloaded installed all the drivers from scratch as it is a new system so it shouldn't be a driver issue. I press ctrl+shift+escape to bring out the taskbar. However it will freeze too including cmd. The Aura effects RGB lights would also freeze. However, the mouse cursor can still move and the video will continue to have audio for a few seconds before it totally freezes. I pressed restart or shutdown but it will take forever until I am forced to press the power on/off button. Sometimes it will be able to wake up from sleep and I had to do a hard restart to get anything on the screen. Is it due to my old GPU card? Tried to reseat the GPU but still the same problem.
