I'm looking for some help or signposts to clear a weird software problem. when i key either numeral 7 or 8 my laptop immediately shuts down and will not restart unless i remove power supply. i have run scans, ccleaner, defragged, culled file but get no nearer than the suggestion this might be something akin to a batch file that has infected.
I'm using Vista
i'm presently googling for ideas and found this forum.
thanks for the opportunity to pose my question.
