Given your description a frozen pipe is the most likely culprit. The best things to do are: keep the hot and cold faucet open as long as someone is home and awake, get as much heat into the areas where the piping runs and you can use a hair dryer or a heat gun (basically a hair dryer on steroids) on exposed piping. Leaving the faucets open will minimizes the chances that the pipe will break. A plumber with a pipe thawing machine can thaw out your concealed pipes if the piping is copper.
