Sorry! I meant to respond to this on Sunday but I got caught up in a project and forgot.
In short, yes. There were problems with the other devices. This was in the 1-2 weeks leading up to Christmas. After we got the power supply for the print bed installed, the Pronterface wasn't recognizing the printer. I did some googling, and most results for how the LEDs were blinking indicated either a bad Arduino or insufficient power. I brought in my Arduino Mega to test with, and Brad helped me find and setup the firmware for RAMPS (because I was having zero luck on the Makergear support pages). We got it recognized and working, except for the X axis and the extruder. I need to print a component for my dad's gift, so I spent a couple days troubleshooting before I found that those stepper drivers weren't working. I ordered a set of 5 off Amazon to get the print I needed.
I don't know what happened to the hardware. When I removed the extruder's stepper driver, the heat sink fell off, and the thermal compound felt like powder. I didn't notice any obvious problem with the X-axis driver or the Mega, though.
