Nikon D3000 Problems. Blurred and spotted?

I have a Nikon D3000 I purchased years ago. I have a spot re-occurring on the top of my photos. It's with both lenses. It occurs on the view finder as well as when I upload them to my computer.

Along with having the spot show up the left side of all my photos that I take horizontally are blurry. I'm unsure if it could be the lenses or if there's something in my settings.

If anyone could help me with this I would be GREATLY thankful.

Have the camera checked at the service center. There's dust or fungal growth on the sensor that's making that spot. Then again, the sensor may also be slightly misaligned contributing to that one-sided blurriness you are seeing.

Thank you so much. I'm thinking about taking it tomorrow to a service center.

What you described is dust on your sensor. Read the manual to find out if the camera has a sensor cleaning mode to shake off any dust. If it does and it didn't work, then you need to blow off your sensor with a Giotto Rocket Blower. You'll need to read your manual on sensor cleaning which will expose the sensor so you can blow it out with the Blower. Just hold the camera with the lens mount facing down and blow out the sensor. Any dust will fall down. Then check to see if the spot is still there (read your manual on dust detection mode where it takes a shot so show you where the dust is on the sensor).
If the spot is still there then either get a wet cleaning kit for sensors or just bring it to camera shop or service center.
