Hello Matt, thanks for joining the Intel communities.
These are some troubleshooting steps you can follow for this kind of behavior:
- Test the system using minimum configuration (motherboard, processor, power supply and one memory stick) out of the chassis.
- Remove the CMOS battery for about an hour. This link shows the process on Intel Motherboards, but you can check it. Desktop Boards — CMOS Battery
If you have access to another system, please check the following link. It also provides troubleshooting steps on Intel motherboards, but it is also very complete Desktop Boards — No Boot Troubleshooting Wizard
