I have been using my D7000 since it first came out. I usually shoot, outdoors, in Manual at iso 500. The other day I was taking photos of all of the cabins on our remote Alaskan Island. I notice the blinking FLASH symbol in the view finder. I was not using any flash. The built in flash was down. No external flash was attached. There was more than adequate light to shoot at 22/320. No matter what I do,the flashing symbol does not go off.

That symbol will flash whenever "THE CAMERA" deems the flash is necessary to achieve proper exposure. What the camera's algorithm that analyzes the data from the light meter thinks and what you deem necessary can often disagree. It really doesn't go to a specific shutter speed, aperutre or ISO setting, but an analyzation of what is hitting the entire sensor.
Just ignore it, or if it bothers you turn Custom setting d12 off.
>why it happening in bright sunlight and, at all meter settings >(spot etc). Why did it just started to happening?
Perhaps it's been happening all the while, you perhaps just began to notice it. And now that you noticed it you are more cognizant of it occurring.
As to the why and wherefore, to know that you would need to know the reasoning behind the algorithm that triggers it. And I don't think Nikon will release it's proprietary info any time soon.
For instance when experimenting in my dungeon (as my wife affectionately calls my basement computer room) when I point the camera at one of the lights, I get a meter reading of 1/800th, f/2.8 at ISO 100 and the flash symbol is blinking. Yet when I point it at the window which is totally covered by a curtain I get a reading of 1/40th, f/2.8 at ISO 100, but no flashing symbol. The difference it that the window curtain fills the frame, whereas the light only fils about 30% of the frame. But if I move the camera so that part of the wall is showing with the window, then the flash symbol starts blinking. So it appears that if a bright are fills half the frame with a significantly dimmer area filling the rest of the frame, the algorithm thinks that fill flash would improve the exposure.
Again that's just a guess on my part from observations on how it responds. And perhaps that is similar to what you are experiencing.
If this is displaying in Matrix metering mode, it means the background is dominate and the fill flash is needed to bring the subject up to balance with the background. Back lit scenes often need flash for balance not matter the overall scene tone. If you are close to the subject, pop the flash or use an external flash on TTL BL mode and see if that does not help a lot in getting a nice balance between subject and background. When you know the back light will cause you problems and want to meter on the subject, switch to spot or center weighted and let the background blow out, the subject will be exposed properly without flash. Portraits or candids in sunlight often have this imbalance between background and subject. After a while you will just know it instantly when visually analyzing a scene and either change your position, the subject, seek some defused shade etc. The dynamic range of such scenes is often far in excess of the camera's range, despite the D7000 having a fantastic DR. Our eyes have a much wider DR. Stan St Petersburg Russia
Thanks for asking this question, I had the same question today for my D90 and found this thread via search. Photographing daffodils; well lit but the background was dark. Flash did not improve the shot.
Playing around, I found similar to Pete. Another reason not to use AUTO I think (so we choose when to use flash rather than camera).
