Need help with 4000 desktop

1) Is it getting to hot?
2) Try cleaning the contacts on the CPU board since these has become corroded in some Amigas
3) Can you try other CPU boards in it?
4) Is the memory fitted properly in the sockets?

well, I don't know how helpfull this is but it is a start.

What kind of hardware is in your Amiga?

hmm.. you could try running it without the case on and see the that works out. It still could be a heat problem because, it could be a "soon to fail" chip or a soldering witch fails when it gets hot.

If you say it freezes in the "instert disk screen" you could try to press gently on every chip and board in it to see if and when it fails, that would tell you if it's a soldering.

Thought I would add my 2 øre :-) I got a lot of lockups because I haven't the newest liberarys for my 060. I think the same goes for the 040.
