Re: Need help now!
There are a couple things that come to mind...
1. I would redo the thermal paste between the chip and the heatsink. Remember, DO NOT just lather freely. The idea of thermal paste is to fill in imperfections in the metal, not to be a separate barrier between the two. Put about two little drops on and then use a credit card like object to spread it out evenly. When installing the heatsink, push it on and twist back and forth a few times to ensure the best thermal paste distribution. Poor thermal paste and heat distribution (depending on previous application) will cause the chip to heat up rapidly, thus invoking the kill switch to prevent damage.
2. (My money is on this) Ensure that the heatsink fan is plugged into the right spot on the MoBo. It reports to the MoBo and gives a 'heartbeat' per say. If the MoBo fires up and can't detect the heatsink fan, it will shut off. The board will live without any fan except the CPU fan unless otherwise configured.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
