Summary:

>The computer was infected with viruses, namely Trojan and Worm Agents which causes the corruption of the Operating System. This is the main reason why the computer cannot boot up properly. In order to solve this problem, re-installation of the operating system without formatting was done in order to have a fresh copy of the operating system file and the virus to temporarily be inactive so we can backup. After the backup process, we re-installed the OS with formatting and now, the computer is functioning well and ready for operation.
