Dell Optiplex GX150 will not turn on properly. It now gives these messages when I turn it on:
Primary hard disk drive 0 not found
Primary hard disk drive 1 not found
Secondary hard disk drive 0 not found
Secondary hard disk drive 1 not found
This is followed by two beeps and a message:
Strike the F1 key to continue, F2 to run the set up utility.
Sometimes F1 key starts up Windows..
