Red VGA Light On, But Everything Appears to Run Fine!

[Justin Blue]

This has been happening for a while but I never really cared to even think about it due to it not effecting my pcs performance. Though I see it as a cars check engine light. I'd rather know what the issue is know instead of letting it cause a big incident in the future. If anyone has a clue as to why this is the case please let me know! I've tried what I saw on a topic similar to the about turning off quick start up, but that was already disabled to begin with.
