My Computer Boot Slowly After Adding Memory

A slow-running computer, even after upgrading the RAM, can be caused by factors such as malware, virus infections, too many start-up programs, too many installed programs, poor maintenance habits or an overly full hard drive. Perform a few simple configuration changes and maintenance procedures to make Windows start up faster

   

Eliminate Start-up Programs

1. Click the "Start" button and the "Control Panel" option. Select "System and Security" and "Administrative Tools." Click twice on "System Configuration." 
2. Locate all of the start-up programs in the window. Uncheck the familiar-looking programs that you do not want to launch when the computer starts up. These may include MSN messenger, Yahoo Messenger, Skype and other applications you might have installed. 
3. Leave the antivirus program checked, as you always want this program to start with Windows. Click "OK" and close the window.

Performance Troubleshooter

1. Go to the "Start" button and click "Control Panel." 
2. Locate the "Search" box in the left side of the window and type    "Troubleshooter." Click "Troubleshooting" in the new window.
3.  Select the "Check for Performance Issues" under the System and    Security category. Wait for Windows to analyze the system for any    performance issues that are causing the slowdown. 
4. Fix these issues or close these issues as instructed by the    troubleshooter.

Maintenance

1. Open your antivirus program and click the "Update" option. Scan the    computer for viruses or malware by clicking the "Scan" option. 
2. Download and install a registry cleaner such as cleaner, Registry Cleaner Free or Wise Registry Cleaner Free. Run the registry to clean up any misplaced or corrupt registry files. 
3. Go to "Start" and "Control Panel" and select "Programs." Locate and uninstall any programs you no longer use. 
4. Eliminate file fragments that over time can make it difficult for the hard drive to retrieve information. Go to "Start" and     "Accessories" and select "Defragment." Click "Analyze" and      "Defrag."
5. Check the hard drive for errors. Go to "Start" and "Computer" and right-click on the "C:" drive. Select "Properties" and click the     "Tools" tab in the new window. Click the "Check Now" link under the     error-checking category. Reboot your computer and start-up should be faster.
