[gcomputers]

Hi to all i m working now with that g62.
Come to me with black screen issue .Some time start hp logo and freeze totaly, reballed NB but no screen , some time start but freeze.

I think is BIOS issue , flashed with 2 dump that i find on 1biosru and one from original HP website but not charge with those dump, are diferent with the original dump.


Does anybody have original dump or can repair my old dump...
Thanks for your time.
