MacBook overheating and freezing
Ive got a mid 2007 2.16 macbook, which i just replaced with a new logicboard. Now my macbook is working but not for long though it starts up and will end up freezing or not responding. I pulled my top case off and placed a fan ontop off the heatsink and the macbook was working fine. So what could be wrong with it ? Bad logicboard, again ? Bad heatsink ? Bad Fan ?
I tried the apple hardware test and it showed a "4sns/1/40000000:tbot error"
Which is usually caused by the battery, so i tried another.. still same error.
Thanks in advance.
Is this a good question?

Did you have kernel panics events with this machine (gray screen asking to restart the computer) ?

I'm not to sure what was wrong with the first logic board. Its symptoms were no boot up chime, nothing on the screen and the power light was on. I got told that the logicboard was dead so i brought another replaced it.

What about the power pads ? Could bad cable / loose connector cause the 4sns/1/40000000:tbot error ?
