got a new pc this year (7900 xtx 7800 x3d) and its been good except for the fact that sometimes my monitor screen goes black for awhile and then the pc restarts. its been happening for awhile now. kind of annoying also worrying. anyone know what it could be? been looking into it for awhile and have no answer.
