kindly solve my problem

With slow booting pc. Start with some house cleaning. Check that you don't have more then one anti virus or malware program running. Use msconfig and under the start up tab turn off stuff you don't need to load at boot.
Run ccleaner and defrag. Clean dust out of the pc and see if there any o,d programs or files you can move to backup drive to free up space on the main drive. If you have windows 32 bit make sure your pc has four gigs of ram to max it out. If you have windows 64 bit and four gigs of ram add some more ram. On your house cleaning also update all of the mb drivers.
