Why need a deep PC cleaning?

Why is my computer running so slow? It is normal for computers to run slower with age. Aging hardware, network issues, junk files, dust are all causes of PC slowdown. If it is the first two, there is no other way but to replace the hardware device or network. If it's the latter two, then you may need to deep clean your PC.

The host will generate static electricity, and static electricity will attract dust. Excessive dust will cause poor heat dissipation and affect the performance of the computer. In order to make the computer's heat dissipation better, regularly cleaning the excessive dust in the chassis can not only improve the running speed of the computer, but also prevent the hardware from being burned out due to excessive temperature and prolong the life of the computer.

▶ Deep clean PC junk files

After using the computer for a long time, a lot of junk files will appear on the computer. Such as caches, unwanted files, corrupt registry keys, duplicates, outdated data, cookies, temporary files, recycle bin files, etc. Since junk files take up a lot of drive space, insufficient drive space may cause PC suddenly slow down or experience other performance issues. In order to make your computer run faster, it is very important to clean up junk files regularly.

For healthy, whether it is junk files or dust, you'd better clean your PC every 3 or 6 months, so as to keep the performance of the computer in good condition.
