Angry circuit breaker possible problem

All winter I had no problems with my electricity and then my lights started to flicker and I had power go off in different parts of my house without tripping circuit breakers. Called local power company and they first said it was from the outside of my house. Then nothing was done so we called again and they sent somebody out and said it wasn't outside. I replaced a couple of breakers and that seemed to help for a couple of days. Then the only problem I had was the lights flickering mainly in the bathroom but today my wife said all the power went out for a few seconds and the light is still flickering every once in awhile. I checked almost all the outlets and they all seem to be fine. I believe the problem is my circuit panel. Is there a way to check it? And if one minute it reads 123.5 volts and the next it reads 121.3 what could be causing this? Should all the circuit connectors, up and down both sides whether or not there is a circuit breaker on them be reading 120 volts because they are not.

Do you have voltage fluctuations before the main breaker? Or is it only after the main breaker? If only after, then the main is probably bad. If before also, then you need to pull the meter out (you may not be allowed to do this), and do the same tests there. If the voltage fluctuates at the input of the meter, then a bad connection exists on the utility side. Some voltage fluctuation is ok though, it's deep sags that are bad.

You need to be very carefull when working inside the panel, there is voltage there all the time.
There will be 3 feeders coming from the meter into the panel. You need to check the voltage between each black feeder and the white feeder. Are the feeders secured? Are the screws tight? If you don't have the tools and the knowledge, you may want to hire an electrician to do this. My guess is that you have a loose connection. Are the problem circuits on the same leg of the breaker or on both? If the same, then that particular hot leg has a loose connection, either in the breaker itself, or before it. If the problem occurs on both legs, then your neutral line has a loose connection.

How do I check it before the circuit board and after. I have an old Murry main switch....hoe do I check that.
