Problems with over exposure Nikon D100

got a D100 trying to make it work right but I am getting an "odd" result
Pretty much no matter what I do it insists on shooting 2 to 8 second exposures. WTAF now I can hand hold a 2 sec exposure at times but as expected the pictures are white way way over exposed. at iso 1000 it should be shooting around 1/10th of a second
sure enough I switch it to shutter priority and set for 1/10th of a second and I get the shot I expected.

Then just shoot shutter priority.

but I switch it back to P program auto mode and its wacked again insisting on taking multi second exposure. I hit the reset button figuring some settings might be out of wack. the camera did reset but it did not reset all settings (it still remembers I had set ISO to 1000 so it did not fully reset)
Suggestions? I thought it was lens but it does it with any lens I put on the camera.
in Program Auto mode (P) it just insists on using multi second exposures.

Have you tried shooting in full manual mode, or manual mode with auto ISO?

Program mode goes back to film days, when the ASA of the film was todays ISO.  Once selecting a film, photographers couldn't select a different ASA, so Program Mode was as "Auto" as a film camera could get.

Today we can select both aperture AND shutter speed in Manual Mode, and let the ISO "float" (Auto ISO).  In other words the camera selects the ISO incumbent upon amount of light and the aperture and shutter speed we have set.  It's very convenient way to shoot in varying light, and still have control of aperture and shutter.  We keep an eye on the ISO the camera is selecting, in case it gets too high in low light, or "bottoms out" in bright light.  If either occurs, then we adjust our shutter speed or aperture accordingly.  For example, my camera's lowest native ISO is 100, so, when shooting in daylight, if I see the camera select 100 ISO, I need to increase my shutter speed and/or select a smaller aperture to avoid overexposure.  It's simple really.

Afterthought ... The D100 was last produced in 2005, so it's old, and could be broken.

Cheers!
