Not sure if this will or not but it a general post about checking on things that might be slowing down the computer.
Computer and browser slowness are not always malware related
Poor performance and other problems can be the result of disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.
Listed below are a few things you can do to improve speed and system performance. Many of the these suggestions will apply if you're using Windows Vista but may be done a bit differently. Near the bottom of this thread there is a section specifically devoted to Vista Users.
For browser problems, see:
If your having connectivity issues or errors such as Page cannot be displayed see
If you're using Vista or Internet Explorer 7, see
If you have a lot of toolbars and add-ons attached to Internet Explorer, you could try improving performance by disabling those which are unecessary. See:
Vista users see:
Clean up your hard drive by removing unused programs and transferring old data, pictures, music files to a CD or an external hard drive.
When you have moved/saved the files you want to keep, run
Disk Cleanup and let it scan your system for files to remove.
Don’t clean out the Prefetch folder - This is a common myth that will not improve performance.
You may be instructed to remove prefetch files if you had experienced some virus/malware issues otherwise removing prefetch files is not really necessary. Although the prefetch folder can become quite bloated in time, removing old prefetch data as a matter of routine is not recommended. Your boot time immediately after clearing the prefetch folder is much slower...but it will speed up after the first reboot when windows begins to put back some of the files that you removed.
As an alternative to Disk Cleanup you can download and scan with
CCleaner.
(Scroll to the last one and click the "CCleaner Slim"...it has no toolbar that comes packaged with it)- After installation, see see the CCleaner Tour: Using and Understanding CCleaner
- Make sure you go to Options-->Advanced and uncheck the box to Only delete files in Windows Temp folders older than 48 hours before running a scan
- An added benefit of using CCleaner is the Issues scan which allows you to clean the registry
- Always back up your registry before making any changes
Check for any unnecessary running services
If you have a typical installation, many services are configured as "automatic"; that is, they start automatically when the system starts or when the service is called for the first time. Use
Black Viper's "Services Configuration" to help fine tune this area.
Check for disk errors by running CHKDSK in "SAFE MODE" or from the Recovery Console
In the Check Disk dialog box, select the
"Scan for and attempt recovery of bad sectors" check box, click "Start" and have it repair anything it finds. As you use your hard drive, it can develop bad sectors which slow down hard disk performance and make data writing difficult. Check Disk scans the hard drive and verifies the logical integrity of a file system by checking for system errors, lost clusters, lost chains, and bad sectors. When encountering logical inconsistencies in file system data, it will perform the necessary actions to repair the file system data.
Check for damaged, altered or missing critical system files by running the System File Checker
If SFC discovers that a protected file has been damaged, altered or missing, it restores the correct version of the file from the cache folder.
You must be logged on as an administrator or as a member of the Administrators group to run sfc and it may ask you to insert your XP Installation CD so have it available.
Defrag your system
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when a file is opened. Disk Defragmenter consolidates fragmented files and folders on the hard disk so that each occupies a single space on the disk. This speeds up reading and writing to the disk. Read
"The Importance of Disk Defragmentation" for instructions.
Note: It is recommended to shut down all applications (including your Anti-virus) before running Defrag to ensure that no programs attempt to write to the drive while it is being defragmented. Not doing so may cause you to have to restart the entire process. If you have disabled all running programs and still find that the defrag routine is constantly interrupted, you can defrag from "SAFE MODE".
Check for any unnecessary applications loading at startup when Windows boots by using MSConfig
Some startup programs are necessary so be careful what you disable. If you are unsure what any of the startup entries are or if they are safe to disable, then search one of the following Startup Databases:
Note: MSConfig.exe is a troubleshooting utility used to diagnose system configuration issues. Although it works as a basic startup manager, msconfig should not be used routinely to disable auto-start programs. It is a temporary solution and not a good practice for several reasons. When uninstalling programs while disabled with msconfig, they may not be uninstalled properly and orphaned entries often will be left behind. When used to switch back to normal startup mode, these orphan entries can result in boot up errors. Further, msconfig does not list all applications loaded in all possible startup locations (some entry points are hidden and unknown to the user) and does not allow the complete removal of disabled entries from its list.
You should not use msconfig to disable startup applications related to a running service. Doing so alters the registry and there are services that are essential for hardware and booting. When you uncheck a service in msconfig, you completely disable it. If you uncheck the wrong one, you may not be able to restart your computer. You should only disable services using Control Panel-->Administrative Tools-->Services.
A better alternative is to use a startup manager. If you have
Spybot S&D installed, launch it, go to Mode and select Advanced. Then go to
Tools, select
System Startups. You will be provided with a list of programs that load when Windows starts. If you untick an entry it will no longer run at startup. This will allow you to experiment and see how your system performs with any of them disabled. Other startup managers you can download and use for free are:
Remove any third party "Memory Manager" or "Optimizer"
Windows XP memory management was designed to make the best use of Ram and these memory management utilities defeat that purpose. They push applications out of RAM into the pagefile, creating holes in the RAM and slowing down your computer's performance by doing so.
Disable some visual effects
While visual embellishments may be attractive, they don’t do anything else for you. Disabling some of them frees up system resources and makes the operating system perform better.
- Right click My Computer, choose Properties-->Advanced then click on Settings
- In the Visual Effects tab, select Adjust for best performance or uncheck all the visual effects, except for the last three
- Click "Apply", then "Ok", then "Ok" again
- Then right click your Desktop and choose Propertie-->Appearance-->Effects
- Uncheck the first two boxes and hit "OK"
Add more RAM
This is a quick solution that can have a dramatic affect on your system's speed and responsiveness. You can check how much RAM you have by going to Start-->Program Files-->Accessories-->System Tools-->System Information and look at your System Summary.

When you are all done be sure to
Create a new Restore Point to enable your computer to "roll-back" to a clean working state keeping all the changes you just made. Then use
Disk Cleanup to "remove all but the latest Restore Point".
