Lcbj - This should be pretty easy on the video side of things. Audio is a little more tricky but still not difficult. It depends on what sort of computer it is and the video ports on it. Most computers will have some combination of multiple video ports (VGA, s-video, displayport, DVI, HDMI etc.) so maybe take a picture of the ports on your computer and TV or let us know model numbers and there is probably enough tech savvy people on here to get you pointed in the right direction. I have a home theater PC set up where I play all of my movies through my computer off of 2 external 1 TB HD's and I can't tell you how many times I have changed around my set up so I have been where you're at.
