2) I am asking question 1 because this machine had a virus... which upon rebooting to complete removal the machine would show the windows moths flying around and coming together, than a fast flash of a blue screen with white letters, then it would begin to boot again... in an endless loop.

I am now part of the "extensive" club which is having major issues with my Inspiron 17R 5720 laptop. It crashed last night and will not boot properly. I have read numerous identical posts which, unfortunately, no solution has been given.

Also I try to reduce as much as possible the brightnes to the minimal 22 but the problem persist and the experiance is not adecuate due the brightness of the two monitors are not equal.
