If you have any experience you could try re seating the heatsink tightly and applying some thermal paste if you have any. If not i am guessing a new motherboard.
Please keep in mind that this is only a guess as i can't actually get my hands on it and test it myself.
Sorry to hear it will take 3 months for a replacement:(

I would be very surprised if the northbridge is causing your problems.
In fact i am pretty sure it won't be the cause. Your power supply unit takes the power from your mains and converts and feeds it into your pc.
What makes you think this is your problem? What are the temperatures?

I was playing Sniper Elite 2 the cpu was at 23c gpu 62c m/b 30c.The n/b temp went to 110c and then poof no electrics,Reset the mains box everything fine,started playing again and after 30min same again opened the pc and a wave of heat came at me,everything was cool except the n/b heatsink which was way to hot to even touch.A while later I rechecked and found that the heatsink on the n/b moves around doesn't seem to seat took the m/b out put old one in and hey presto no problems,put the new m/b back in and bingo keeps tripping the power.So can you give me an explanation?

AH well it sounds as if you the heatsink isn't properly attached to the northbridge.
Those are very high temperatures being so high and it could cause the problem.
I would replace the faulty motherboard before those temperatures cause problems for your other components
