Why do computers get slower over time?

Answer 1

Besides the technology becoming dated and therefore slower than when compared to newer models, there are a number of factors:

Excess of old and redundant software. Every time the computer boots it loads small fragments of these old programs which are not necessarily used.

The disk drive becomes fragmented, meaning that data for a single program or file can be stored over many physical locations on the drive. This means the read/ seek time when accessing the file is slower as it has to physically load from a number of disk locations.

Easiest way to speed up an old computer is:

1. Uninstall all old programs that are no longer needed on the computer.

2. Empty the recycle bin, delete all old temporary or cache files (ie. Explorer cache files).

3. Use a program such as Piriform CCleaner to find and delete all old registry entries from the file registry; you can use the same program to delete old temporary and cache files.

4. Use a disk de-fragmenter program to consolidate physical files on the drive so that the access speed is increased.

ALWAYS MAKE A BACKUP BEFORE RESORTING TO SOMETHING LIKE THIS, DO NOT DISTURB THE PROGRAMS ONCE THEY START CLEANING UP YOUR PC, THIS CAN CAUSE FILE CORRUPTION.

Answer 2

There are many reasons that cause a slow running computer:
* Bloated registry with errors
* Fragmented registry and hard disk
* Too many junk files take up the memory
* ......

In order to speed up computer, there are quite a lot of work to do: clean and fix registry errors, defragment registry, clean hard disks, optimize Windows system, etc.

Most of these tasks can't be done manually, thus you'd better use a Windows system optimizer to have them done. Go and learn such software and you will know how to speed up your computer.

Answer 3

When some registry errors stores in registry of computer it slows down your PC......This will decrease speed of our PC..............
