I cannot ask further questions. It seems that this option is blocked or damaged in my PC. How I can resolve this problem?.

Including your deleted questions, you have asked $50$ questions in the last $30$ days. That is the limit.
It used to be the case that a message was presented when you tried posting the $51^{\text{st}}$ question, but there was a request to prevent asking the $51^{\text{st}}$ question so that people wouldn't spend time writing the question only to be told they can't post it. I am surprised that the option is not available, and that a message is not displayed when attempting to ask a question.
Possible Feature Request: Enable the "Ask Question" link and display a notice informing that the user has asked $50$ questions in the last $30$ days, and tell them when they can ask another question.
