Here steps to take – why is my computer running so slow

Reboot

If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below. Rebooting the computer can fix many problems and is an easy first step.

Background programs

One of the most common reasons for a slow computer is programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots. If you have an antivirus scanner on the computer, spyware protection program, or another security utility, make sure it’s not scanning your computer in the background. If a scan is in progress, it decreases the overall performance of your computer. If this is the case, allow the scan to complete, and the computer’s performance should improve.

Delete temp files

As a computer runs programs, temporary files are stored on the hard drive. Deleting these temp files help improve computer performance.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size and give room for temporary files.

Bad, corrupted or fragmented hard drive

Check the hard drive for errors

On a Windows computer, run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer’s hard drive.

Scan for viruses

If your computer is infected with one or more viruses, it may run more slowly. If your computer doesn’t have an antivirus program installed, run Trend Micro’s free Housecall online utility to scan and remove viruses on your computer. We also recommend you install an antivirus program for active protection against viruses.

Scan for malware

Today, spyware and other malware is a big cause of many computer problems, including slower performance. Even if an antivirus scanner is installed on the computer, we recommend running a malware scan as well. Use the free version of Malwarebytes to scan your computer for malware.

Hardware conflicts

Verify that the Device Manager has no conflicts. If any exist, resolve these issues as they could be causing your problem.
