Sensor scratched or dirty?

Thought id give my sensor a check by taking a pic of my pc screen and adjusting the levels in PS to bring them out more.to my horror i found lots of specks and the camera is less than a year old.
not sure if that is dust or scratches. will go out on monday to buy a blower. the in camera "dust removal" did nothing to the spots.
oh yeah and there is also a tiny spot in the viewfinder.hopefully the blower can get rid of that if its on the mirror.

Looks very clean to me.
Mine looks dirtier most of the time.

I see a faint blue line at the top of the image and several well defined specks. Most likely dust, you had it stopped down to f32 so they would be more sharply defined. Try opening up the aperture and see if the specks get less distinct. If they stay the same they might be dead pixels on the sensor.

No idea what would cause the blue line.

the blue line is from the white screen which could have been flickering from the frequency.u get that when trying to capture a tv or pc screen.
at a larger aperture they do become less distinct and cant really be seen below f14

No scratches - just what look like dust specs to me. I suspect that the line across the top is a function of monitor you were taking a photo of.

Do the spots show up in normal pictures? if not, I would leave it alone till they started to impede your regular images.

If you go looking for problems, you're bound to find them. Better to wait until they find you and then deal with them, less anxiety I find.

I know a shop by me and they swear by that sticky stick, remember to still hold they camera up ide down and blow it vigorously and then proceed. And only dab the sensor do not wipe it with that sticky stick .Good luck
