Yep, relatively straightforward really but asumes your router has vpn en-point capability and you can leave the pc at your house switched on.

Setup a dial-up vpn account on the router at your house, probably better to stick with PPTP to begin with until your comfortable with the setup process then you may wish to secure it with an ipsec compliant vpn at a later time.

Moving on . . . decide on a remote client access application (such as RDP or VNC - free) and enable/install the server side component on the PC at your house. Once you are happy your pc can be acessed locally across your own home network (by way of test from another computer running the relevant client side application) then you should be in a position to setup the dial-up vpn client at the remote location (in this case, your parents house). Use the built in wizard to create this vpn dial up network connection and make sure you enter the relevant details when prompted (you will need the WAN IP at your house and any credentials that you programmed onto the router for the dial up account when you created it). Lastly, where relevant, install and setup the client side software on your parents pc for the remote access application you chose earlier.

There you have it. You can now vpn to your home network, take control of your home pc (via whatever remote access client you opted for and to the private IP assigned to your computer at your home) and surf the net from you own pc as if you were sitting at home in front of it.

Note, many people make the common mistake of trying to setup vpn's between routers with common (or the same) private network addresses at each side of the connection. Each private side network needs to be different else the vpn will be unable to route traffic across the connection.

Hope this makes sense . . .
