Hi pote2639
Actually, the latencies in your screen-shot don't look that bad. The problem is that Latency Checker 1.4.0 doesn't produce reliable readings (it hasn't been updated since Windows 7). The Performance Monitor built into Windows 10 can produce a more accurate glimpse into the DPC situation for your computer.
Since the computer is so new, though, I think you'd be best off taking advantage of the warranty period, and have the manufacturer's techs take a look at it. You shouldn't have to spend hours and hours troubleshooting a brand new computer - it should work as advertised right away. And there are always some models that have "known issues" ... that your manufacturer knows about, and can repair/replace quickly.
Best of luck
