I can see a marked improvement in the boot up process; it much swifter now. I can't be much more objective as I'm not a tech savvy guy. Hope you understand. Thanks for all the help! By the way, in one of the earlier messages, you've mentioned that my USB drives need tobe taken care of. May I ask you what are the procedures for it. 
For your information, I've two pen drives, one HDD, a printer, an additional monitor and occasionally my android phone used by laptop (the current system).
