Check your computer’s speed and malware by UPCleaner

Add more memory

This isn’t a guide to buying hardware that will speed up your computer. But no discussion of how to make Windows run faster would be complete without mentioning that you should consider adding more random access memory (RAM) to your PC.

If a computer running Windows 7 seems too slow, it’s usually because the PC doesn’t have enough RAM. The best way to speed it up is to add more.

Windows 7 can run on a PC with 1 gigabyte (GB) of RAM, but it runs better with 2 GB. For optimal performance, boost that to 3 GB or more.

Another option is to boost the amount of memory by using Windows Ready Boost. This feature allows you to use the storage space on some removable media devices, such as USB flash drives, to speed up your computer. It’s easier to plug a flash drive into a USB port than to open your PC case and plug memory modules into its motherboard.

Check for viruses and malware by UPCleaner

If your PC is running slowly, it’s possible that it’s infected with a virus or malware. This is not as common as the other problems, but it’s something to consider. Before you worry too much, check your PC system using the best pc optimizer.

A common symptom of a virus is a much slower-than-normal computer performance. Other signs include unexpected messages that pop up on your PC, programs that start automatically, or the sound of your hard disk constantly working.

Malware is a type of program that’s installed, usually without your knowledge, to watch your activity on the Internet. You can check for malware with Windows Defender or other anti malware programs. For more information, see How to tell if your computer is infected with malware.

The best way to deal with viruses is to prevent them in the first place. Always run antivirus software and keep it up to date. Even if you take such precautions, however, it’s possible for your PC to become infected. For more information, see how can I tell if my computer has a virus?

Check your computer’s speed by UPCleaner

If you try these tips and your computer is still too slow, you might need a new PC or some hardware upgrades, such as a new hard disk or faster video card. There’s no need to guess the speed of your computer, however. Windows provides a way to check and rate your PC’s speed with a tool called the windows experience index.


The Windows Experience Index rates your computer on five key components and gives you a number for each, as well as an overall base score. This base score is only as good as your worst-performing component subscore.

Base scores currently range from 1 to 7.9. If your PC is rated lower than 2 or 3, it might be time to consider a new PC, depending on what tasks you want to do with your computer.
