Computer won't connect to a monitor

[Angus_7]

So, whenever I turn my pc on it doesn't connect to my tv/monitor or any other tv/monitor. Also my system fan works for a few minutes then goes on to full power and shuts itself off while my CPU carries on running. PLEASE HELP!!!

Always list all the parts in your PC.
