Sims 3 crashing in create a sim. and is it bad to delete user presets files?

[qwerty8857]

My game kept crashing when it went to create a sim. It only does it when I want to create a woman and I scroll down to view the clothes. I went to delete my caches and I noticed a user presets file that was never there before. I thought that maybe it was the cause of my crashing because my game wasn't crashing yesterday, and I don't remember seeing that file before. I deleted it, but my game keeps crashing in create a sim and one time it crashed before the game even loaded. I deleted all my caches and I don't have any custom content. I also did everything on here and nothing worked:

My graphics card isn't good enough and I have to run the game on the lowest settings, but usually I can play. Most of the time it crashes every one in a while, not every time I try to create a sim. When it crashes the screen goes completely black. Is there any way to get out of this without restarting my computer? Escape, ctrl+alt+delete, and the windows flag button don't work.
