You can get your system specs from this website including motherboard make etc: http://support.hp.com/us-en/document/c04796698

The good news is your motherboard supports "1 PCI Express x16 (Gen 3.0)" which is what you put your graphics card into.
The bad news is you have a "180 W uATX aPFC internal power supply." Now unfortunately that's not enough wattage to run a dedicated graphics card, I'd recommend upgrading to at least 450W. Bear in mind you can't buy any old PSU. Because this system is pre-built and it uses an uATX form factor I'd recommend contacting HP and enquiring about the possibility of upgrading it.
