Why is the CPU usage rate 100 when watching TV with video and audio?

Reasons for high CPU usage:

1."Poor heat dissipation": the monitor, power supply and CPU generate a lot of heat during work, so it is very important to have a good ventilation condition, if the monitor is overheated, it will lead to color and image distortion and shorten the life of the monitor.

Working too long can also cause the power supply or monitor to dissipate heat poorly, causing the computer to crash. CPU heat dissipation is an important issue related to the stability of computer operation, and it is also the "hardest hit area" where heat dissipation failures occur.

2."Dust killer": Too much dust in the machine can also cause crashes. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, and in serious cases, it will cause the computer to crash.

3."Software and hardware incompatibility": For example, 3D production and some special software may not be installed or started normally in some computers, and there may be software and hardware compatibility problems.

4."Memory module failure": This is mainly caused by loose memory modules and their quality. Faults in memory module corners should be eliminated on a case-by-case basis, and if there is a problem with the quality of the memory module, the memory needs to be replaced to solve the problem.

There is a virus problem.

You may have fallen for a Trojan horse, a worm, or a rogue software or plug-in. Hardware is also possible. In line with the principle of soft before hard, it is recommended to choose Kaba to upgrade the antivirus software to the latest version and virus database antivirus.

Then the next Security Guard 360 scans the system to clear the rogue and plug-ins, and patches the security patches. If the computer can't solve the problem after restarting, then remove the computer and clean it to strengthen the CPU fan heat dissipation, which is generally okay.

Maybe you don't have the driver installed, you right-click"My computer"properties, in"Hardware"tab"Device Manager"Click on it to see if there is a yellow question mark or exclamation mark on the graphics card. If there is, then install the disc that the graphics card driver is in the graphics card box. All the way to the next step is fine.

If it doesn't work, it's a hardware problem, most likely a graphics card cooling problem or a motherboard failure.

Sell an exhaust radiator.

Or dust and see.

Too normal Luo, I atom dual-core general poison is not less than 80%.

The CPU usage is 100% due to insufficient GPU performance.

**The processor (Central Processing Unit abbreviation: CPU) is a very large-scale integrated circuit, which is the computing core and control unit of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

Graphics Processing Unit (GPU), also known as display core, visual processor, display chip, is a microprocessor that specializes in image computing on personal computers, workstations, game consoles and some mobile devices (such as tablets, smartphones, etc.).

When the GPU is unable to complete the task, the system will increase the CPU operation to achieve the required performance, resulting in 100% CPU usage.

The CPU is too old, and the god horse is still in the age of galloping!!

1. Hardware:

2) Low graphics card performance: The low performance of the graphics card will increase the amount of CPU computing and increase its proportion. If it's an integrated graphics card.

You can consider replacing it with a discrete graphics card, or replacing it with a discrete graphics card with better performance, especially strong hardware decoding capabilities.

2. Software:

1) Running memory.

Insufficient: There are too many auto-start programs at startup, or too many front-end software are running at the same time, resulting in insufficient running memory and increasing the amount of CPU computing. 360 Security Guard is available.

Optimize acceleration and clean up memory on a regular basis.

2) Software issues: There may be problems with the support of some software, or the settings are not correct, or the cache is not cleaned up, etc. These need to be adjusted in a targeted manner.

Maybe it's a version issue, you can update it, or change back to the old version.
