      That's too bad, was worth checking, though.

        Not sure which generation you have, but here is a link to all the light codes and beep codes:

          @scottalanmiller No beeps unless memory is removed. Otherwise, high fan speed, indicator 2 and 4, no video.

          What are the beeps that you do get when the memory is removed?

            I'm guessing the graphics card is integrated on an SFF.

              @rojoloco Yes, it is integrated. I don't have a pci express to test, but I am not sure if it will post anyway with the video error.

                Reseat the minimum amount of memory, see what it does.

                      @scottalanmiller Tried that. Also cleared cmos. No change. Still black screen, high fan speed, solid green power light, and indicator 2 and 4 lit.

                        Do you have anything plugged into that box that could be removed? Any extra cards, USB or anything like that? If so, remove them.

                        If not, likely the mobo is dead.

                            I think that likely the desktop is just dead, then. unless you can acquire a replacement motherboard, of course.

                              @reid-cooper I tend to agree. I will look for something.

                                Probably worth retiring that box. How old is it?

                                    Not ancient, but might be time to retire it.

                                      @reid-cooper Maybe I can find a cheap mobo and give it a few more years. Thanks for the insight!

                                        Possible, if you can find one cheaply.
