Thank you for posting on the Micro Center Community and I apologize for the issues you are having when it comes to your PowerSpec! How were you installing your Graphic Card Drivers? Through GeForce Experience? Something you can try is taking out one stick of RAM, and seeing the performance with just one stick of RAM due to the DRAM light being on. If it still stutters, switch it out for another stick as well as try different slots.
It does sound like you eliminated a lot of the software issues however and every solution I am looking at looks to be a hardware issue and require you to bring it into the store.
A clean Windows install is really the last step of troubleshooting, if you are still getting blue screens after that, it would most likely be best to bring this by the store under warranty.
