Issue with brand new HP Pavilion Slimline

Good evening all. We just replaced my wife's failing Apple iMac with an HP Pavilion Slimline computer. We took it out of the box today and set it up around 5 P.M. Shortly after setup, 5 crashes occurred by 10:30 P.M. Posted below is information from the crash log as well as the dump file. If someone can offer me feedback as to what the issue truly is, that would be great (based on debug, I'm fairly certain it's a hardware problem). I'll also attach the .dmp file for those of you more computer savvy than myself.

Thanks!
