Greywolf1: Your description doesn't sound like a codec problem (which are associated with videos and sound most of the time) to me. And I don't know anything about community codecs GOG recommends.
It does sound like a problem with mods, and possibly with the transition from one PC to another. Are you using a mod which has to do with cliffracers, your equipment or spells, or the area in which these encounters happen, or something similar? And are you sure that the configuration of Morrowind of your new PC is absolutely identical with the one of your old PC, where you created the save game? This may include different versions of the same mod or activated / not activated mods.
These differences may cause crashes whenever a mod on your new PC is trying to do something that was not possible on your old PC, or expects to find something which isn't there.
This is not an exhaustive answer, I know, but it's difficult to judge something you don't know well enough - I'm also not clear if the problems you describe are associated with your new PC only, or if they were also present on the old one (if it's the latter, I would consider a corrupted save game). You might try different old saves (if you have them), do a new clean installation of Morrowind and start a new game, and you could also have a look if Wrye Mash (a mod and savegame management utility) could be useful for you.
If you still have your old PC, re-import the save game from your new PC to the old one, and run it there ...
Well gog support page says usually to use combined community codecs package.
I am not using any mods for cliffracers,equipment and spells probably the mcp 2.4 one that i added to it.
One thing is strange that i have 81 maxium health on the bar shown yet when i hover the mouse over it it says i have 82 health which it doesn't reach for some reason.
Also i noticed that a sword that has electricty doesn't properly run out of charge when i hit enemies and i was using that sword so something is broken i think or i don't know how it properly works.Old pc was pretty unstable and had to underclock it to make it work so it could also be a problem with randomly crashing,but usually it was with cliffracers crashing my game when i was attacking them and they attacked me in larger numbers. When i made the transfer to 2.4 mcp i just updated it from 2.2 (which mcp says you can do) which was on old pc and there was one file from mcp 2.2 that didn't get added in 2.4 so when i loaded the game on a newer pc with fresh install and adding all the mcp 2.4 patches it warned me about the file that was missing in the save game that i transfered from old pc,but i continued anyway.
Also ingame i am at 31 day and level 8 high elf mage custom class called magic blade i kinda don't like that i will have to restart the game now since i made some progress with some guilds and quests.Trying out god mode on new game with cliffracers or the current save game from my longest progress several monsters were attacking me but it didn't crash.
Btw how important is Morrowind patch project (Mpp) for this game?
