Artifacting/Glitching during exports out of Premiere

Hey all,

I have had this persistent issue that i've never been able to nail down on my exports. I have searched through the topic, but never found a post that directly matched mine.. I have been having an issue while rendering out files from Premiere where there are scratches/glitches/artifacting randomly on my export when I check it. I have attached a screenshot below to illustrate. I have had some success with rendering out using Software only. Has anyone had any similar issues or maybe know of a fix? What might be causing this problem?

Any responses are greatly appreciated! Thanks!
