The first day after it came back, everything was stellar. They exchanged the entire cooling system, and sent it back. Out of ideas, I used my guarantee to send it to an MSI store for repairs. But everything seems to be wasted effort. So far, I've tried a lot of things - plugging the laptop pc in, updating the drivers, setting the proper graphic card as default while running games, disabling whisper mode, disabling fps limits, changing priority, shutting down background programmes, lowering graphic setttings of games, running as admin, uninstalling Mcafee, turning off battery boost, cleaning out the dust, adding a cooling pad. Also, my wallpaper sometimes turns black. So here is the issue I'm struggling with: After about a minute of smooth processing (70–130 fps), my games grind to an agonising 30 frames per second.
