Most computers begin to suffer stability problems with continued use, although to a different degree that may depend on different factors. Reduced stability that manifests itself in various PC errors may be caused by a wide array of issues, most of them related to the Windows registry and the damage it may have sustained.
Advanced PC users may be able to fix Microsoft Windows XP, Vista, Win 7 or 8 problems by manually editing the registry or removing individual keys found to be corrupt or invalid, as well as applying other manual PC bug fixes. Users may seek professional help from an IT technician, who can help avoid a full PC crash, fix PC power supply and other hardware, as well as clean the computer from issues that may be causing stability problems or general malfunctions. However, since any manipulations with the registry always carry a risk of rendering the operating system unbootable, whenever a user is in any doubt of their technical skills or knowledge, they should only use special software that provides safe PC fixes and is meant to fix system errors and other computer problems without requiring any special skills.
