malfunction warning?

[3corey2]

what are some of the signs that my pi is not working to its full potential or is malfunctioning? is a red light bad is a error pop up after start bad? do these things make a difference if everything seems ok and runs?

If it's working, it's working. Full potential is a little more difficult to judge, but generally it will be trying as hard as it can.
