Yes I had tried ALL the solutions mentioned and nothing worked, not even the fresh re-install. I posted the solution that worked for me. I am not urging anyone to follow it, but if ALL other solutions don't work then there is mine that worked, that's all.
Thanks everyone for your concern but my problem is solved and if you make backups of your pictures, the bookmarks and settings of your browser(s) (chrome excluded, if you have a gmail account your settings will be intact) and everything valuable to someone
(I don't mean the backup of Windows but a backup of those files on a different HDD) than it is not a big problem, not for me anyway.
