Hi Daysan, this is posted in the wrong place and that is probably why nobody has helped you, if you post questions in the Daz or Poser forums you'd get help within a few hours.

Generally those are indications that the render hasn't gone on for long enough. When there are reflections or light spots, they're dealt with last in the render engines - if you tell me what render engine you're using, I can give you an example of how to change the settings to solve those.

For example, with Iray, there is a setting "progressive render" and you would have to increase the maximum samples allowed, and the maximum time allowed so that Daz will continue rendering the image until it has dealt with all the sparkles.
