These are some of the common reasons why my computer work slow all of a sudden, and some measures you can take to fix that problem.
Tip 1: You Have Too Many Startup Programs
According to computer experts, the most common reason for a system (computer or laptop) to work slowly is— too many startup programs.
If you download a new program in your system (computer), it will try to scramble their way into your startup menu and starts as soon as the system boot. This would elongate the time of booting and also the initial lags to the system. However, approx 90 percent of all programs require permission to start when your system (PC or laptop) is starting.
So, when the system boots up, there are tons of additional calculations is done by the processor to starts all these dozens of useless programs. This, will slowing downgrade the overall performance of your system, as even after the startup, they are consuming your vital processing and memory resources that you and your system don’t require at that time.
How to Fix it?
On Mac: Application> system preferences> user group> Login Items> uncheck unneeded programs.
Windows 8 and 10: Press Windows + X> Task Manager> Startup tab.
Now, you have to right-click on the program which you want to remove from the startup menu and select Disable.
But there are some programs that should be allowed to run from startup menus such as antivirus, firewall software, iTunes, or other important drivers.

Tip 2: Your Hard Drive is Failing
Failure of the hard drive is also a common reason for slow computer performance. After 3 to 4 years of continuous use, there is a greater chance that a hard drive gets failed because these hard drives have a mechanical rotating disk that rotates millions of times a day. So, it get degrades with time.
In case you are using solid-state drives (SSDs), you may have a better experience than standard hard drives because SSDs have a lifespan of about eight to ten years, which is 3 to 4 times higher than a normal hard drive. It also works ten times faster than a standard hard drive.
How to Fix it?
Windows 7/8/10: Open Windows Explorer> Computer> right-click on drive> Properties> Tools> Check Now. If it shows a problem, try to use the troubleshoot option.
Mac: Firstly open the application head, then utilities. It will open a new dialog box. Click on Disk Utility and then highlight the hard drive in question. And at last, click “First Aid” which is at the top of the screen.
Tip 3: Your Hard Drive is 100% Full
When your hard disk capacity encores at 95% to 100% then it means that your system can’t use additional data from the hard drive to compute the next operations. This means that the overall performance of your system drops to 50% or even low.
In short, it means that there is no space available at this level to save temporary files that require operating programs to operate. If the OS does not know how to run applications on a full hard drive, it will slow down your computer.
To get a better experience of the hard drive once again, you may have to free up a significant amount of space by deleting the files you no longer need. You can also backup some files on clouds or some external hard drives.
How to Fix it?
To fox it, you have to find and delete junk files or files that you no longer use. Try to backup some important data on the remote cloud backup and external hard drives.

During web browsing, if you are using a 4GB Ram variant PC, then opening a lot of tabs might slow your computer speed. This is because, whenever you open a new tab in the web browser, the data is saved in RAM (Random Access Memory).
So, if you didn’t have space on it, then the system deviates some of its tasks to the hard disk, which of course, works slowly. This also happens when you open heavy blog pages or auto-refreshing web pages such as a live blog.
How to Fix it?
The best way is that you can bookmark those necessary links and shut down all unnecessary tabs. You can also use the Chrome and Firefox web browser instead of the default browsers because it can compile all the open tabs into a single list so that you can easily access as per the requirement and also takes less RAM space.
Tip 5: You have an Overeager Antivirus Program

A dusty pc could be the reason why your computer work slows. This is majorly due to the deposition of the dust on the motherboard, processor fans, SMPS, etc. This majorly affects CPU performance as these dust deposits over the cooling fan can make the CPU to heat up quickly that decreases the CPU performance.
This happens because the CPU is designed in such a way that it cannot get damaged with the heat. So, when the heat is beyond the expected markers, the CPU slows down its performance and even stops and shut down the pc.
How to fix It?
To clean a desktop CPU, you can either disassemble each of the components and reassemble them after cleaning them with a dry brush. For a laptop, you can use compressed air cans, to blown-off all the settled dust.
