In my 1040 it was the memory controller. The ST was sensitive to the slightest
tremor, so I opened it up, and touched the ICs. I took out the culprit, cleaned
it by scratching the contacts of the IC and the socket, and put it back together.
Everything works fine. One warning: visit an electronics store first, and get
a anti-static wrist band to connect yourself to the Atari PC board. CMOS is
not as sensitive as a few years back, but those Atari ICs are expensive.

Opening the ST was not very problematic, I only needed pliers and a set of
screwdrivers. Be careful when you take these LLC ICs from their sockets.
