System corrupted when trying to reset time desplay. Screen went black then came on in dull gray with "triangle containing skull and bones" in center of screen. This was a new install a week ago of Mepis 7.0 Linux, replaceing Vista. System has been better than perfect since install untill this happening. Am presently wiping the whole system with Killdisk to reload. My question is... Does any one have a clue, of what it might be? It is deffinately new to me. Thanks.
