Performing system cleanup without using HP Support Assistant
A computer's hard disk drive can have a major effect on system performance. Over time the hard drive can become cluttered with unwanted or temporary files, the data can become fragmented and stored in an inefficient manner, or there may be disk errors on the drive itself. All of these issues can impact system performance, and all are easy to maintain. This section describes methods to maintain hard drive performance through removing unwanted and temporary files, checking the hard drive for errors, and defragmenting the drive.
Removing viruses and spyware with Microsoft Security Essentials
If the computer is performing slowly after connecting to the Internet, adware or spyware programs might be installed. Spyware and adware software programs use the Internet to download and upload data in the background. Some of this data might be sensitive information or unwanted advertising. Removing these malicious programs will improve the performance of your system. For more information, see About Spyware, Adware, and Browser Hijacking Software.
Microsoft Security Essentials is a free download for all computers running a genuine version of Windows. It provides protection against viruses, spyware, and other malicious software. Information on downloading and using Microsoft Security Essentials can be found in the document Using Microsoft Security Essentials to Protect Against Viruses and Spyware.
Managing applications in Windows 7 to improve system performance
Having unused applications installed to the hard drive, or leaving applications running when not being used, can both have a negative impact on system performance. This section describes how to remove unwanted applications and close applications that are not in use.
Managing startup programs by preventing background programs from loading
A startup program is software that opens when Windows opens. Over time, as you install more and more software programs, the number of small icons on the notification area increases (usually these icons are in the lower-right corner, next to the time). Each of these small pictures represents a program running in the background, and each one uses valuable system resources. Move the mouse pointer over each icon to identify what software it is. Common programs that load and run in the background are security software, Windows Update, instant messaging software, and multimedia programs. You can increase system resources by stopping some of these tasks from loading, or by changing their settings. This can be achieved in a variety of ways because these programs open from various different places.
This section describes how to remove unwanted startup programs using System Configuration and the Startup folder.
Upgrading memory
Upgrading memory can improve system performance. You can upgrade random-access memory (RAM) on most HP and Compaq notebook computers. For step-by-step insturctions please see the help document HP Notebook PCs - Upgrading Memory (RAM).
Adjusting System Restore settings in Windows 7
System Restore is a feature of Windows that can revert system software and settings back to a particular date. System Restore does this by saving the changes made to system files in a restore point. These restore points use a lot of hard drive space. System Restore uses up to four percent of the hard drive with restore points if left unadjusted, regardless of the size of the hard drive.
 caution:
If you are experiencing system problems and may need to restore your computer to an earlier time, DO NOT remove the restore points.
 caution:
Selecting Turn off system protection will prevent the system from creating future restore points. You cannot restore the hard drive without restore points.
The following sections describe how to reduce the hard drive space system restore uses and how to manually create a restore point.
Turning off nonessential graphical features to improve system performance
Graphical features and programs can use a lot of system resources. Turning off these features can improve system performance. This section explains how to adjust visual effects for best performance and how to disable Windows Aero.
Reducing heat inside the PC to improve performance
Heat buildup can cause problems for any computer. Generally, when temperatures inside the case rise above 95 degrees Fahrenheit (35 degrees Celsius), the risk of damaging important internal components increases greatly. The most common cause of overheating is the accumulation of dust inside the computer. The electrical components in a computer generate heat and fans inside the computer help move the air to keep the components cooled to normal operating temperatures. Inadequate cooling can cause excess heat to build up inside the case which can damage components and decrease system performance. The sound of the fan running constantly may indicate that the computer is not running as efficiently as possible and that there is a problem with accumulated dust clogging the air vents.
Follow these steps to reduce the risk of your computer overheating.
  1. Computers have vents located around the case to allow air to flow through the case. If these vents become clogged or heat generating parts become covered with dust, the fan cannot cool the components properly and overheating can become a problem. Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder. If there is dust in the vents, you should clean the computer by blowing out the dust from around the fan and heat shield. This prevents dust from accumulating.
     caution:
    Ensure that the computer is turned off and the AC adapter is disconnected before spraying with compressed air to prevent damage to the PC.
    Use a can of compressed air (a vacuum cleaner on blow function or a hair dryer in cool air mode can also be used, though the can of compressed air is better suited for this task) to remove dust from the computer's vents and prevent overheating. Removing the dust increases the air flow to improve cooling and allows the fan to run quieter.
    The cooling vents are located in various places depending on the PC model. You can identify the vents by looking for the copper or black fins inside the vents. You should also blow the compressed air into other openings such as the fan intake vent to help keep the air circulating and prevent dust from accumulating on components. By taking this action periodically as a preventive measure, you can greatly reduce the possibility of component damage and prevent the slowdown of the computer's performance.

  2. To decrease the likelihood of overheating problems, ensure the fans on your computer are able to ventilate properly. Proper ventilation for the system is important for system operation. Follow these guidelines to ensure adequate ventilation:
    • Keep the computer upright and on a sturdy, level surface.
    • Provide at least 6 inches (15.25 centimeters) of clearance around each vent.
    • If the computer is being used at high altitudes, above 5000 feet (1500 meters), take extra care to keep the computer cool. The maximum limit of 95 degrees Fahrenheit (35 degrees Celsius) drops about 2 degrees Fahrenheit (1 degree Celsius) every 1000 feet (300 meters) of altitude.
  3. If using an HP Notebook PC, HP CoolSense technology can modify your notebook computer's temperature by using its motion sensor to determine whether the computer is being used in a stationary environment or a mobile one. By using this information it automatically adjusts both computer performance and fan speed to keep the computer cool. You can set HP CoolSense software to your specifications. For more information on this see HP Notebook PCs - HP CoolSense Technology.
  4. If your computer is overheating, place it in a cooler room. A small difference in temperature might be all that is needed to prevent a component from failing. Move the computer to a cooler room in the house or office. If this is not an option, continue with the next step.
  5. If overheating issues persist after cleaning the vents and moving the computer to a cooler room, a hardware component might be damaged. Test the computer to see if any hardware, such as memory, the processor, or the graphics hardware, have failed. Most HP and Compaq notebook computers have diagnostic software to verify hardware failures. For more information, see HP Desktop PCs - Testing for Hardware Failures (Windows 7) or HP Notebook PCs - Testing for Hardware Failures (Windows 7, Vista).
    If hardware has failed, either replace the bad component or contact HP for further assistance.
