SOLVED THE PROBLEM!!! :dance: For me this wasn't script related at all! My windows vista 32-bit only uses 2GB virtual memory by default. I enabled the 3GB SWICTH (just google for it) and now all my CTD's are gone. I mean ALL OF THEM! not only near windhelm. Near goldenglow estate (west of riften) f.e. works fine too. Well, ok, i still have freezes sometimes in the triangle northwest from Darkbrotherhood sanctuary, but that's pretty sure because I lack Video memory (only 512mb and i have some texture replacers, for the mountains f.e.). Monitored the usage of the vRAM, it was over 500 when the freezes occur and it started stuttering before freezing I think the CTD's near windhelm wear related to my increased ugridstoload=7 and with only 2GB Virtual memory it simply couldn't store the huge information for this area. The weather change to sunny probably decreased this information but now I can have a cold windhelm again like it's supposed to be.
