Nikon n80 blurry photos?

I haven't used my camera in quite a few years. I'm just getting started again and don't remember much of what I used to know. I never had any trouble with photos before but suddenly the pics are blurry even in auto mode. Camera store said it looks fine (lens too). Any suggestions on why pics might be blurry would be happily accepted. Thanks!

Added (1). I guess I wasn't clear. I'm capturing a still image and the pics are out of focus. Lighting is good and I'm not too close to the image.

Blurry, as it looks like they move? You don't mean blurry like out of focus blurry, right?

The shutter speed is too slow to capture the action of the subject(s).

You should check these Item:
1- you can't take photo of moving object in low light if you have NOT proper lens( it is very expensive)
2- you should check shatter speed shutter speed should be high enough to freeze object
3- sometime you should increase ISO (specially in low light)
4- you should turn on your VR ( vibration reduction) if you have proper lens
5- sometime camera focus in wrong object you should try manual focus
if you check all item ypu can add additional information
