Your Question is not clear.

This is the third time I have formatted the subject for you. I'll explain again: When you write the subject text IT SHOULD SAY SOMETHING ABOUT WHAT YOUR QUESTION IS ABOUT. Not just "Help Me".

PLUS: Your spelling sucks! Doesn't your keyboard have any "shift" key so you can write capital letters? It's "I" - not "i". And questions are normally terminated by a question mark. If you were to put a little effort into writing your questions, people would be more inclined to answer them...

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

Try:

...
Random r = new Random();
int questionNumber = r.Next(0, numberOfQuestions);
AskQuestion(questionNumber);
Timer t = new Timer();
t.Interval = 10000;    // 10 seconds
t.Elapsed+=new ElapsedEventHandler(OnTimedEvent);
t.Start();
...

private static void OnTimedEvent(object source, ElapsedEventArgs e)
   {
   Timer t = source as Timer;
   if (t != null)
      {
      t.Stop();
      }
   FailedToAnswerInTime();
   }

There are some details, like keeping the Random object as part of your class to ensure it is different each time, making sure you don't ask teh same question twice in a session, etc. But those you can handle with a bit of thought.
