Surely all Internet users are already accustomed to the fact that on the pages of numerous sites it is possible to view videos. And almost everyone knows such an unpleasant effect as a slow video.
Major hardware issues
Like any other electronic device, a computer can also break down. Most often, one of the devices ceases to function normally, however, in this case, not only the slowing down video appears, but also other freezes. But situations are possible when this manifests itself precisely on videos viewed via the Internet. The reasons may be in the RAM or the processor. Only replacing them will help here.

If the video on the Internet freezes, then another reason may be the video card. Even if it functions normally (i.e., the monitor shows an image), this does not mean that it is operating at full capacity. In this case, you need to check the drivers for the video card - they may have been damaged, not installed at allor outdated.
If the video you are watching is of high quality (for example, HD), then there are often cases of lack of hardware resources. There are a number of requirements for devices, failure to comply with which leads to the braking of high-quality video. Only replacing computer components will also help here.
By the way, the higher the quality of the video, the more Internet speed is required. Therefore, a low network connection speed also leads to video slowdown: it does not have time to load in a timely manner. You just need to pause the video and wait for it to fully load.
Slowdown video: software issues
If drivers are installed for all the necessary devices, they all work properly and are the latest, then most likely the software is the cause. What should be checked first? And the first thing you should pay attention to is the plug-in for the Internet browser, which displays video from the pages. The most commonly used today is Flash Player, which can fail from time to time. However, the browser itself may behave “inappropriately.”

In order to find out if a plugin or browser is really bad, you can use the task manager. Press Ctrl, Shift, Esc at the same time. We go to the "Processes" tab from above and find the name of your browser (for example, Opera.exe, Chrome.exe, etc.), look at the "CPU" and "Memory" sections. If you have only 1 GB of RAM on your computer (1048576 KB), thentoo high a figure in this section (about 30-40% of the total memory, in kilobytes) indicates that the browser or plugin hangs. If the percentage rises to 80-90% in the "CPU" section, this also means that the browser or its plug-in is hanging.
The first step is to change the browser and go back to the "Task Manager". If the picture repeats, we update or reinstall the plugin, downloading it only from the official site. You can also try clearing your browser's cache, cookies, and removing all other plugins from it.

Sometimes, even after this, a slow video can remain so. In this case, you should pay attention to the possibility of viruses infecting your computer. Usually, viruses also greatly slow down the entire system or any individual program - in this case, your browser. You should scan the system with the latest antivirus database.
If the video on the Internet continues to lag, then the operating system itself may be the last reason for this. This is also a fairly common problem. Laggy video may appear as a result of the fact that the OS incorrectly processes video streams, requests from various programs, etc. (many reasons). In this case, you need to reinstall the OS or completely restore it.
So, by solving all of the above problems, you can eliminate the causes of video freezing. But in many cases, a simple restart of the computer can help.
