Where did my boards go? (???!!)

I have a 4000T that is doing something similar. Some of the cards disappear from my early boot menu and no longer function after booted. It only happens after my 4000T is warm though. I have thought about getting some of that electronics freeze spray and spray a components and reset, repeat until working. I wonder if Radio Shack has some. I just bought a new 400W AT power supply hoping it might fix the problem but it didn't make any difference. My 4000T is an (early) Rev 2 with 40.70 ROMs and my main accelerator is the CSMK3 which is very similar to yours. Hmmm.

It has a hand written sticker that says...

Ser. No. 2

The board is yellow and has a socketed buster 9. Still came with a lithium button cell soldered on. I can't see any leaking on any of the caps on the motherboard or other boards and I know what to look for. They could certainly still be a problem though. I tried to take pictures but they came out crappy. The closeups were all fuzzy, most of the farther shots had glare and I couldn't figure out how to turn off the date in the lower right hand corner. It's a borrowed digital camera.

Good suggestion. I'll try bending in and cleaning my Buster socket and carefully bending out the buster chip pins slightly. This doesn't help AMIGAZ though.

@AMIGAZ

Thanks for the update. It gives me hope. I'll try changing a few things as well.
