Download Google and other browsers to test it. If it works, use the software when watching videos or browsing other web pages. These are all without IE as the kernel, which does not conflict with your use of IE (the main reason is that the browser is not easy to use, and I picked it out from multiple browsers in practice. This browser is famous because it is not easy to crash, because the problem of each page will not affect the whole browser. Ask me if you have any questions.
In addition, be careful not to do other operations at the same time while watching. If it's a website's own problem, look at it another time.
If you watch it for too long, it is easy to go wrong. My own experience is that you can just watch it for a while and restart the computer.
If you watch online video on the software platform, it is more likely to go wrong. There is no better way. If the software platform is not easy to use, then change it, change the time period, and don't do other operations while watching it. In short, be careful.
If it is due to hardware, it is usually caused by small memory, high CPU temperature and slow network speed, but this is not the main problem, mainly because the browser is not easy to use, and other operations are being done while watching videos.
The above answer is what I did when I watched the video. If you have any questions, ask me.
