My computer is running slow, what steps can I do to fix it?
All computers get to a point where they start running slow and sometimes freeze up. If this is happening at work please call me. But if your home computer is acting this way here are some things you can do to speed it up. You can always ask me if you need help.
Tip: This page only covers an overall slow computer and not a computer that has a slow bootup or slow Internet. Below are steps for Microsoft Windows users that can help speed up the computer or determine why the computer is running slow.
If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below.
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.
Tip: 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 Resmon to get a better understanding of how your computer is being 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 can decrease 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 can help improve computer performance.
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.
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, as well as room for temporary files.
Today, spyware and other malware is a big cause of many computer problems, including a slow computer. Even if an antivirus scanner is installed on the computer, we recommend running a malware scan on the computer. Use the free version of Malwarebytes to scan your computer for malware.
Scan for viruses
If your computer is infected with one or more viruses, this can cause your computer to run slow. If your computer does not have an antivirus program installed, you can run Trend Micro's free Housecall online utility to scan for viruses on your computer, as well as remove them. It is also recommended that you install an antivirus program for active protection against viruses.
If you have done any of the above steps but your computer is still acting slow try rebooting the computer again at this point.
If you have had your computer for more than two years, you may need more memory. Today, we suggest computers have a minimum of 1 GB of memory (RAM) for 32-bit system and 2 GB for a 64-bit system. 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.
Hard drive upgrade
One of the biggest bottlenecks of a computer is the hard disk drive. Upgrading from a hard drive to a Solid-State Drive (SSD) can significantly improve the performance of a computer.
Make sure your computer and processor is not overheating. Excessive heat can cause a significant decrease in computer performance because most processors automatically reduce the speed of the processor to help compensate for heat-related issues.
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 fans are not obstructed.
Erasing everything and starting over can increase performance by getting rid of old software or drivers that may be on the computer and causing the computer to be slow. 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.
Finally, if your computer is still slow after trying all of the above recommendations, there may have a more serious hardware related issue, such as a failing component in the computer. Examples of failing hardware could include a failing or bad hard drive, CPU, RAM, motherboard, or another component.
You can run hardware diagnostic tests using the Ultimate Boot CD (UBCD) utility. This utility provides many diagnostic tests that you can run and determine if your computer has a bad piece of hardware.
If your computer is more than five years old, the age of the computer could be the cause of the slow performance. As more advanced software programs are released, they are optimized to run more efficiently on newer computers. Older computers are not able to run these new programs as well, which can cause them to perform more slowly. We recommend that you consider purchasing a new computer or accept that your computer is not going to be as fast as a newer computer.
