Hi guys,
I have an old dell optiplex machine (I need it as I have old hardware that only runs on XP). Been working fine for a long time but the other day I was using it and got the blue screen of death. When I turn it on now I get 6 bleeps and nothing coming up on screen. Any idea what's caused this??
