Does playing games on a computer always damage it?

First of all, it depends on what kind of computer you buy and what kind of hard disk you use.

The only damage that can be caused by downloading is the number of readings and writings that occur when the data is copied and the burden on the hardware when the data is processed.

To be more precise, it is the hard disk problem. In other words, if you have a problem with your computer because of downloading, it's a bad hard disk.

Hard disk problem here, divided into 2 kinds, one is the traditional mechanical hard disk, and one is (Tablet, Superbook, Notebook) solid state hard disk.

Mechanical hard disk, in the high-speed download, the hard disk to run at high speed, a long time will be a burden (heat), easy to break.

Solid state hard disk has read and write limitations, repeated copy read and write large data will be illuminated by the trial life is reduced.

But I think your worries are unnecessary. Because SSDs can be used for at least 4-5 years.

And mechanical hard disk, as long as you do not long uninterrupted download. Basically, there is no problem.

And with that said hard disks have a practical lifespan of just over 2-3 years. And hard disks are cheap.

What are you afraid of. If it breaks down, you can get another one.
