Just the question. Don't use "plz help!!!!" or even the less neurotic "please help". If you didn't need help, you wouldn't be posting here in the first place. Just end your question with an actual question that asks what you want to ask.
Something like:
Foo is blah blah blah blah and I need it because blah blah blah.
Sadly, I cannot foo on my machine because blah blah and when I try, I get blah blah and blah blah. I tried to fix it by doing blah blah, but it blah blah and gave me blah blah error message.
How can I manage to foo on my machine?
