First of all, 3 words:
"Technical Support Forum"
Then, notice the stickies, particulary the one stating "How to beat the Black Screen of death".
Now, don't panic. The "of death" part is only the name the people have given this problem. It isn't really death, it can be solved.
As for your problem, it's caused by a faulty script, it could be any script in your install. To know the problem you need to get us something called a "Console Report", the sticky I mentioned before goes into getting one. Feel free to ask if you are getting any problems.
