stollendesigns on "Error when uploading files to wordpress"

I am new to wordpress and having issues uploading images to my site. I just started getting an "HTTP Error" and "Failed to write to disk" error. I didn't get these before and haven't installed any new plugins. I don't know how to fix this. My files are the right size and kind. I checked the forums and they are saying how to replace all this code but I see any of that on my wordpress dashboard. Also my site is hosted by godaddy if that helps.
Thanks,
Rob
