You many face boot hang problems during the boot up of Windows 7 operating system. Hanging means booting cannot be processed after starting the boot process. Slow boot problem indicates that it takes a long time to complete the boot process; from starting till the end. Virus or malware infection is the main reason for the boot process hanging. If your PC contains many startup processes, you may face slow system boot up. Also limited RAM space could result in the slow boot process.
