GoDaddy page shows up instead of my site

My site was working perfectly, but now when I go to the site I see a GoDaddy page instead. Tech support told me to do a DNS flash and empty the browser cache. I did that and still my site does not appear. Any ideas as to how to get it to show up permanently? Since it worked before I assume it was set up just fine. Thanks!

Have you checked the tld DNS pointers (at your registrar… GoDaddy?) to make sure the domain points to DreamHost?
And that your domain registration is valid (not expired)?
