I just finished putting in sockets, the capacitors, and 2 resistors
on my 520STfm motherboard (rev D) where it normally is in a 1040.

Now, with or without the sockets populated, you turn the machine on, it
displays that typical blank screen for boot but with a white stripe
going across it about 2/3 or 3/4 of the way down from the top

with some dark pixels on the bottom of the stripe.  When one turns it off
and on again, one gets rows of a dark pixel pattern (blotches in a pattern)
on this same screen.  (Guess that the video RAM gets junk in it.)
The disk drive is NOT accessed.  It just sort is dead.  I've looked at all
the traces on the board, can't see anything shorted, etc.

Any suggestions?

Thanks,
Chad
