caffeinated.joy thanks for the tip! 
The photos are here:



Notice that all the decorations in the neighborhood are with the texture of snow, but snow should be on the floor does not appear.




Also note that in lots where the soil had to have snow turns blue.

The mouse cursor when the snow begins, it becomes a "blue cube". 



A download may have done this? 

How do I put pictures on this site?
Could you explain please?
If I put images you'll see what happens and you can tell what is happening.
 

First thanks for posting ... 
But I ran my game in windowed mode and it was the same thing ...
And so ... the images that you were left more or less my problem ... But the color is blue and not purple ...
And the blue color only applies to the ground and not to other objects too ...
As you said, opening the task manager, CPU usage comes to about 50%.

My computer is:

Windows XP
Intel Pentium Dual]
1.60 GHz
1.00 RAM

You will probably say that my computer is not good ...
But never denied a game, such as The Sims 2, I have all expanções and almost all collections of objects.

Translation: Portuguese / English: Google Translator.
thank you! 

I have the expansion pack 4 seasons, but every time it snows, the snow on the lot is not bright white ... And with a blinking blue color ... and in the neighborhood she gets graphical errors too. 

Before it did not happen ...
Just recently it 

Help me! 

What I liked best was one that inspired me in the game GTA San Andreas ...
It was very similar.

There was a cabaret
