Computer owners should be ready to face the fact that any moment, the computer will slow down. The older it is, the bigger the chance that the computer will slow down. So what are the main reasons why a computer tends to slow down? Well one reason can be linked to the actions and the effects of spyware, viruses and hackers. Once a computer becomes infected by a virus, then that computer starts to slow down. So one when that happens you have no other option but to introduce some form of repair. Slow computer affected by viruses and Trojans can be addressed by using many anti-virus programs that can be purchased and that can come for free.

To effectively repair slow computer, you have to remember that its slow performance isn't always related to malware. The slow performance of the computer can also be linked to disk fragmentation, disk errors, corrupt system files or the presence of too many start-up programs. Other culprits include unnecessary services and programs running and not enough RAM in the system. And as the system and the computer gets older and the computer is already filled with more and more files and programs, then that computer has now the tendency to slow down. And your reaction should be to conduct some repair. Slow computer should be cleaned by.

This can be done by effectively removing the rarely used programs and software and you can also transfer the old data and some files to a CD or to an external hard drive like a flash drive. The moment you already transferred the files and data out of the system, then it is suggested that you run the Disk Cleanup and allow this to scan the system for files removed. And make sure that you don't clean the Pre-fetch folder. To repair slow computer, you need also to check for any unnecessary running programs and services. The simulation game that you downloaded may be nice, but if this is rarely used then might as well remove the program to lighten the load of the computer. Fine-tune the many programs and software inside your computer by manually doing that or by using third-party software.

When you repair slow computer, keep in mind that a disk errors can be the culprit as well. You can address that by checking for disk errors by effectively running the CHKDSK in Safe Mode or you can do that from the Recovery Console. Also check for the damaged, altered or any missing critical files by running the System File Checker. This checker is necessary in a sense that once it discovers the protected file has been damaged, missing or altered then the System will restore the correct version of the file. To run this System, just make sure that you log in as an administrator. Defragging the system can also do the trick but exercise care when doing this type of repair. Slow computer that is scheduled for defrag should be ready. All applications including the anti-virus programs should be turned off.
