You have probably heard that tweaking your system you can significantly improve your PCs performance. Although, that statement is true, do not try to do it just by moving settings or altering the system's registry if you have no idea about Computer Diagnostics, or at least the basics of your system settings, use and abuse.

In cases like this, PC diagnostics software is particularly rewarding, because not only you can determine if there is any failure or wrong setting affecting your system performance, but also to find where the settings are that you need to modify manually to improve the performance.

After running the PC diagnostics for the first time, try to clean up your system registry on a daily basis. Most users are unaware of the huge amount of useless information that the registry saves. Computer diagnostics often return a list of "orphan" entries recorded in the registered and staying there forever.

Those orphans are the result of installed and uninstalled programs with information that is retained in the registry, the same as unused drivers, spyware and other issues causing conflicts that slow down the system. Running PC diagnostics software or editing the registry manually using regedit.exe or other utilities will help you to improve performance.

However, be carefully making changes to the system register because you can cause major problems. That is why it is preferred that one uses Computer diagnostics applications instead of doing a manual change of the settings.

Another problem causing system slow down is a Recycled Bin full above the 80% mark. Due to the large amount of data that can be stored on modern hard drives, the Recycled Bin usually sets up automatically a large amount of disk space to let you throw away whatever you do not want... and sometimes what you want, discarded by mistake.

You do not need any PC diagnostics software to know that your desktop trashcan is almost full. Empty your Recycle Bin at least once a week to release hard drive space that improves PC speed performance, even when Computer diagnostics tools are used, as they will not have to scan the useless files when running.

Whether manually or with the aid of PC diagnostics applications, one of the most tedious, but necessary tasks to do in order to improve your PC performance is run your disk defragmentation. Due to the large size of actual hard drives, this process may seem never ending so run it once quarterly, but do it.

Some PC diagnostics software includes a defrag utility, otherwise you need to use that which is part of the Windows operating system, but before starting you need to run another native PC diagnostics application "scandisk". Without scanning your disk first for possible errors, defrag may refuse to continue its defragmentation routine.
