Flaky A4000

[Bodie]

Hi all,

I recently pulled out the A4000 from the cupboard booted it up and was pleased to see it booted up okay.

However, I have found that after consistent usage it will constantly freeze up. No gurus etc. There is no consistency to the freezing, it can strike any time. The machine has been stripped to the basics (no expansion cards etc). I have tried different ram sticks etc

I have an Apollo 4040 in it - but alas I no longer have the original Commodore board. The Apollo does appear to get very very hot after these crashes.

One thing I did notice when stripping down the A4000 is that it did not have the plastic insulator. Could this be causing it to freeze up constantly??

Thank you all for the help.

The good news is, the hangs and crashes are largely gone. Mainly just by improving the cable management and air flow in the case. I have some small cooling parts on order to further maintain the cooling. The a4000 seems to functional well now with an surf and cv64/3D.

The only other issue I now have is a failure to boot at times. I suspect this is down to a faulty chip ram simm, so awaiting on a new one from Amigakit now.

Re caps, there appear to be no leaks on the board, however, I have found someone who can do the capping ... And has a repair store just 2km away! Will also get a new PSU or have the caps replaced in the original PSU.

Overall, good to see the a4000 up and running again, thanks all.
