Mac does not see internal or external hard drives

So I have an early 2011 macbook pro that does not see any hard drives at all in disk utility. It worked fine up until recently, and I have tried several different drives both internally and in external docking stations. All drives and docking stations work fine on other machines.

The computer DOES see SD cards however, making the problem all the more confusing. Does anyone have any ideas on what could be causing this? I suspect a faulty motherboard, but would like any other ideas if anyone has encountered this before.
