  1. I got the message: "Operating System Not Found" on startup and may be lucky to have it booted the second time I hit the reset button, sometimes I have to restart 3,4,5... times or turn the power OFF and back ON for it to work. Before it happened once in a while but it is everytime I start the PC now. I did check all the connections, cables,...to make sure everything OK but such problem is still there. Any help is greatly appreciated, thanks!

    This intermittent behavior could be a sign of a faulty hard disk.

    You may want to run a disk diagnostic on your drive to verify it is good.

    Check the storage forum near the top for more info on disk diags.
