I've been playing around 200h of Skyrim and I've noticed, that when I try to use a 20+ number of mods with my game that individually change only portions of gameplay and graphics, and are not incompatible with each other, I get CTDs more and more frequently. It effectively kills my enjoyment, and roleplaying effort.
I'm desperately looking for some way to make the game more stable. Please tell me anything that can help!
I have Win 7 32bit, 4GB RAM, Latest ATI/AMD drivers, anti-virus running. I'll post my mod load order, and dxdiag if needed.
Thanks in advance!

I blamed it on cowardly horses mod, but I'm not sure about that either... I'll try to remove it next time and see.
You are very helpful! I'll try these suggestions tonight.
