How long did your old computers last before they died?

My first A1200 was perfect for about a year before it developed the "A1200 AGA graphics fringe" bug (overheating Alice, but no one knew that at the time).  I got it replaced under warranty just before C= went under.  Second A1200 developed same issue a year later.  Picked up a used A4000.

I've never heard of this problem before, is it a common problem with a1200's?, does it affect a4000's?

In another thread I think alexh said heatsinks should not be put on plastic packaged IC's, but should I put heatsinks on all my alice chips anyway?

Are there any other known issues which I do not know about, is there a list somewhere?

If the fringing problem only occurs on a couple of a1200 revisions, that might suggest an electrical or positional problem. so if we can see what changes were made to later boards we might be able to prevent the problem on earlier boards.
