?There are hundreds of different devices available to use with PCs, including printers, memory sticks, digital cameras, CD-ROM readers and many more, and these are manufactured by different manufacturers and have different operating intrusions. Device drivers are a kind of program that tells your PC how to operate a particular device, and all PCs are built with a specific number of device drivers installed into the system. However there are so many different devices you might not install each single version onto a PC, and new versions are being created all of the time, so when you purchase a new device you'll often receive an installation CD ( or you will need to go to the manufacturers websites for the even if you de-install or update old devices from your computer, the driver can still remain in your system, and after time this means that your driver files ( generally with a suffix of or EXE or DLL ) can become cluttered and disorganised, making it tougher for your operating system to find the driver it needs to run devices efficiently. This could cause a number of operating issues, from slow performance speeds to difficulty opening applications, and will even cause major PC instability, with system crashes and possible blue screen blunders. therefore as part of your usual PC upkeep you need to run a device driver scan, which is a cleaning program that will scan your Driver Robot files and identify any outdated, corrupted, duplicate or new drivers and clear them from your system. You can get a free basic driver scan from web sites such as Driver Cure, Driver investigator and Driver Robot, and these also supply a more in depth driving scanning software for those folks that are having major issues with their driver device registry.
