Some people including myself have encountered the problem that when I open the “My Computer”, the disk C shows a red bar. It means the disk is almost full and has very low space, which can cause Windows to run more and more slowly, and even can be reason why your computer often crashes. In this case, you need to free up disk space to fix Windows 7/8/10 running out of space.
