I deduce this from the fact that at one point I can suddenly see the mouse pointer - but only within a rectangle which has the size of a small video-window.
However, I can see nothing. All I can see is the overall parchment background and the mouse pointer - which is visible only within this ominous rectangle - but nothing happens.
I had significant stability problems with Morrowind as well, and I dont think it was the mods that caused it (more likely some conflicting piece of background software) since I had the problem in vanilla as well.
A startup problem was part of the mess. I dont remember exactly what my startup looked like, but IIRC first I get a loading screen with parchment and some monster model and maybe a progress bar. The trick was to either left click or press escape after the progress bar had run its course. If I just left the game to its own devices it would hang and never reach the main menu. Maybe your problem is similar?
And my main mod recommendation is the No-Glow mod.
