Hi,

I have a SE/30 with shows strange behaviors. Here the list of them:

First, and it always did that when I received it, when open the monitor is displaying horizontal lines for a while, then the staring chime happen (after a few minutes) and it can boot.

Recently, I saw it doing that again, then, when booted, I wanted to go on the HD and it started to be very slow. After that, it never booted up correctly.

Can it be the logic board doing such problems?
