How to fix a slow computer?
One of the most common reasons for a slow computer are programs running in the background.
Below are steps for Microsoft Windows users that can help speed up the computer or at least determine why the computer is running slow.
3. Delete Temp Files
First, we suggest using the Windows Disk Cleanup utility to delete temporary files and other files no longer needed on the computer.
Unfortunately, the Disk Cleanup may not delete every file in the temp directory. Therefore, we also suggest deleting temporary files manually. To do this, open the Start menu and type %temp% in the Search field. In Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field. Press Enter and a Temp folder should open. You can delete all files found in this folder and, if any files are in use and cannot be deleted, they can be skipped.
2. Background Programs
One of the most common reasons for a slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.
To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resource Monitor to get a better understanding of how your computer resources are used.
If you have an antivirus scanner on the computer, spyware protection program, or another security utility, make sure it is not scanning your computer in the background. If a scan is in progress, it will decrease the overall performance of your computer. If this is the case, allow the scan to complete, and the computer’s performance should improve.
4. Free Hard Drive Space
6. Scan for Viruses
It is also recommended that you install an antivirus program for active protection against viruses.
5. Bad, corrupted or fragmented hard drive
- Run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer’s hard drive.
- Run Defrag to help ensure that data is arranged in the best possible order.
- Use other software tools to test the hard drive for any errors by looking at the SMART of the drive.
7. Scan for malware
Use the free version of Malware-bytes to scan your computer for malware.
8. Hardware conflicts
10. Update your drivers
9. Update Windows
If you are on the Internet when your computer is slow, make sure all browser plugins are up-to-date.
11. Reboot the computer again
12. Memory upgrade
By having enough memory for programs to run within memory, your computer will not need to swap information stored in memory to the swap file. If the hard drive light is constantly active, it can be an indication the computer is frequently swapping information between your memory and hard drive.
14. Computer or processor is overheating
Dust, dirt, and hair can also constrict proper airflow inside your computer, which can cause a computer to overheat. Make sure your computer case is clean, and that the fans are not obstructed.
13. Hard drive upgrade
15. Erase computer and start over
Erasing everything on your computer and reinstalling the operating system can increase performance by getting rid of old software or drivers. Installing a fresh copy of Windows, software programs, and the latest drivers help verify there are no software related issues causing your computer to be slow.
