I recently had a problem with the GS, which I thought somebody on the net might
be able to identify (the problem no longer exists).

I turned on my GS and was greeted by a random checkerboard-ish pattern.  The
power light on the keyboard was on, but the power light on the TWGS remained
off.  Then, I took out the TWGS and put in the original 65816 (making sure that
it was tightly seated) - same problem as before.  So, I put the TWGS back in
and turned the system on again, and same problem.  This time, I pressed hard on
the TWGS pins going into the CPU socket (while the computer was on), and all of
a sudden the checkerboard turned color, and the system booted.  The problem no
longer exists. 

Any clues on what could be causing this, so I can take appropriate preventive
measures?  I don't expect it to have been caused by loose chips since I made
sure that all chips were seated well after the first boot.  The problem first
occurred on the first boot after a move, if it matters.
