Extreme heating problem with HP Pavilion g6-2312ax. I have opened my laptop and found that the copper rods have turned black. Is this the reason of excess heating and shutting down?

Laptop has already been cleaned but to no avail.

Processor

While you have cleaned everything have you verified the the fan(s) are working?  To turn black that had to get really hot and i wouldn't be surprised if you have some hardware component damage.  Other things to check: make sure you are applying new TIM(thermal interface material) as well as applying it properly(a little goes a long way). Make sure The heatsink is sitting completely flat and that it's properly secured.

The more I look at this the more I think that it's black paint to match the laptop case.

Notice the straight line where the black ends on the left hand side of the fin assembly.

If it was overheating, you would see discoloration starting at the heat sinks and working its way outward.

I more often than not post from mobile and pictures on a small screen can be hard to discern.  With that said I am sitting at my PC and I concur with you.  That is not from over-heating.  That was painted to hide the shiny stuff through a slot in the case or some other aesthetic reason.  My other advice still stands ratulaich​  I suspect a fan(s) that have failing bearings/bushings that are allowing it to only work intermittently.
