There must have a short cicuit, you must check with DMM, or you connect the capacitor in reverse direction ??

It sounds like you've got a major fault. Did you make any checks before you plugged your project into the mains?
Based on that, I don't think you should be experimenting with mains powered projects.
There's a certain level of care you need to take, such that even if there is a fault, it should not cause
the entire mains power in your room to go off. That's a sign that you have not spec'd a correct fuse, or
an even worse fault, before we even get to the root cause of the problem.
