I gotta say, I would've never thought of baking the motherboard. Makes sense in regards to overclocking and as the op stated, he constantly ran his MBP. Baking, I guess, would kinda resolder connections...total guess.

My recommendation, I repair devices all the time now, after you remove all the little screws and the piece you need (like a motherboard or pcb), take the time and put every screw in the hole it came out of. Trick I learned as a mechanic. It helps prevents losing them and guessing, since sometimes screw threads and height vary.

I usually make a map of the board and use masking tape to fix the screw to the map.

Yeah, if I'm running a fast fix (like pull a battery, ect.) I'll usually arrange the screws in an orientation to how I pulled them out, but long fixes like the op had (or when your waiting for parts)... I put the back in.

Not a bad idea with the masking tape, guess a magnet would work too.
