Why the computer slow down?

If you usually use a computer, you'll find that over time, you've run into a common problem - computer slowness. Why does the computer slow down? The following are possible reasons.

✦ C drive is full. C drive refers to the system disk. When the C drive space is insufficient, it may cause the computer to slow down or even computer freeze.
✦ Malware in the computer. When malware invades the computer, it will automatically generate a lot of useless files to occupy the PC space.
✦ File fragmentation. The distribution of file fragments in the computer can also reduce PC work efficiency. Because when reading a file, the head needs to keep jumping around the disk to find the file fragments all over the computer.<
✦ Too many junk files. If too many junk files accumulate in your computer, your computer will undoubtedly slow down.
