What if the video in the win7 computer cannot be buffered?

What if the video in the win7 computer cannot be buffered? So what should we do if we encounter such a problem?
The first situation: the video cannot be buffered, probably because the video corresponds to insufficient write space on the disk, so we have encountered such a problem, first of all You can check to see if the video corresponds to the directory or if there is a red emergency in the disk space. If this is the case, we can choose a larger directory as the cache space.
The second case: network restrictions. Everyone should encounter such a situation. For example, in a company, opening other programs is very fast, but when it comes to such a video website, it will be very slow. In fact, this is because someone has set a network limit. You need to modify the settings, otherwise you can't solve it yourself.

third case: the use of Chinese writing to the directory. This is a mistake that many friends are likely to make. In the system, writing to the directory is not allowed in Chinese. If there is Chinese, there will be a failure.
