Operating System Troubleshooting and Reinstall/ Repair

The Operating System has a number of responsibilities:

1. It must keep all the programs and background tasks executing, which is known as process management.
2. It must provide file services such as reading, creating, and modifying files on storage devices.
3. It must allocate and deallocate blocks of main memory, which is memory management. A key part of memory management is virtual memory, in which a larger main memory is simulated through the use of the hard drive.
4. It must route events, such as user actions, to the appropriate program, and then route program actions to the proper output device. In general, this routing forms the connection between application programs and the devices in a computer system.
5. It must protect programs from interfering with each other or with files they should not access.
6. It must store key data about the system and applications that run on it.

All these responsibilities are very important, but sometimes happen failures of the occur Operiting System. All computer faults can be divided into two types: the failure of hardware (PC component failures), and errors in the software component (OS, drivers, antivirus and other software). In the latter case, you may need to reinstall your operating system. Most often, such a need arises after the defeat of the operating system viruses.
