I have windows 10 that I just uploaded and installed last week without a hitch, well at least until tonight. I left my HP Z 200 Intel i7 2.93 w16GB RAM and an nVidia Quadro 4000 card, with a 240GB SSD, and 750GB HDD. on all day, which I don't normally do, but I forgot. So when I turned it off it made a reference to the install of windows and when I tried to start it back up that is when I get the 6 beeps...Please help me. I am 69 but computer literate and a lot younger than my age in thinking.
