I think most irritating thing happens when you are doing some urgent work and
the PC gets slow! Okay! Don't be worried!
Just follow the rules below which'll instantly boost
the performance of your PC!
***Backup files
Most of us have the hideous habit of downloading stuff like programs,
audio, and video files and letting them remain on the hard disk drive.
This affects the overall performance of the HDD which reduces the speed of your computer too.
It is way better to back up these files on DVD disks or on a portable drive.
***Clean the registry
A brand new PC contains only the operating system and a
couple of other programs that the vendor included as a part of the deal.
However, each time you install a program, it writes information on the operating system's registry.
Unfortunately, the process of uninstallation only removes the files and folders of the software.
Traces of that program remain in the registry, bloating it.
Use a dedicated registry cleaning program to remove these traces.
***Defragmentation
Use the defragging software of your operating system
to remove clutter from the hard drive and arrange folders and files in a contiguous manner.
This can speed up computer significantly.
Perform this task on a weekly basis.
***Anti-virus
Install a good anti-virus software plus an anti-malware and update their signatures regularly.
Malicious hackers often use Trojan programs to control your computer remotely and use it to send DDoS attacks.
Removing malware can boost the speed of your slow computer.
***Remove unnecessary auto-start programs
When you reboot, some programs automatically start up, sapping your machine's resources.
Remove programs you don't want to open
when you restart your computer and that should make it a bit faster.
