problem with davinci

perhaps it's all because of the video card. or is it not so? maybe you know how to fix it. all the actions I hope will be clear on the video. in short: over time, everything or almost everything freezes, the menu buttons that are located at the bottom do not work. clip preview is not included. the video card is loaded up to 100% and the program no longer works adequately.
