I honestly think it has something to do with OBSE or DeadlyReflex, game crashes about once an hour on average. Not really a huge deal but I would like to fix it. I recently reinstalled after taking a break for a few months, never had a crash before installing newest version of OBSE.

Are you starting Oblivion with obse_loader.exe? re you patched to 1.2.0416?

I'm very surprised you don't have the Unofficial Patches loaded in. I see that a lot. It's amazing how many people don't have them loaded in.

Also, since you say you've added OBSE & another mod, load-order is getting to be critical. FCOM Helper is best.
