I recently added another 4 Meg of memory to my SE/30 and soon after
noted that the monitor started to "flicker".  The flickering occurs when 
the system has been up for a while and is "warm".  To be more specific, I
get horizontal lines at the top and bottom of the screen that appear and 
disappear. With each occurrence, the entire screen image jumps 
slightly.  This anomaly is not fatal but it is annoying.

Common sense tells me that the new memory has nothing to do with the problem,
i.e. this is either a coincidence or I touched something I wasn't supposed to
when I had the case open.

Are there any Mac doctors out there who have an idea why this is happening?

Thanks in advance.
