Macbook crashing after recent repair

[phishstix]

My macbook was turning itself off a lot, and I surmised the fans might be broken and it was overheating. I took it into Apple, and they replaced my fans along with my main logic board, display bezel, connector, and heatsink. I was told I basically got a new computer, and I better have for $300 dollars!

I received it on Friday. Today, it has been randomly restarting itself all day, and the kernel panic message has appeared about six times or so.

What could be going on?! I literally just got it fixed.

I literally just got it fixed.

Oh dear! By the sounds of it, you didn't!! I would get it straight back to Apple and politely tell them to sort it out properly. Good luck!

When is it doing it, idle or in programs?

i would do the following

1. Reset the PRAM
2. Reset the SMC
3. Verify the disk permissions
4. Verify the HDD

If it is a potential heat problem,you can open terminal up and run yes > dev/null This will cause the CPU to use 100 Percent usage there for generate heat. If it does this then i would suspect a over heating problem and take it back.

I had this problem with the first gen macbook the heatsink was getting to hot and expanding it was touching the Logic board and shorting it.
