There isn't really any problem at Hogwarts, not that I know of, unless you can specify when this supposed "problem" was. There are always issues RE Voldemort but these aren't always related to Hogwarts
Book 1. The Philosophers Stone plot
Book 2. There was the Chamber of Secrets plot
Book 7. One of the Horcruxes was there
But thats all I can think of, try reading the books if you dont know.
Voldemort.
voldermort is taking over harry potter so he gathers a team to toughen up

In what ways is the final resolution of the whole Harry Potter series foreshadowed in the first chapter?This is actually a good question for the first chapter of any book.
The names of the book in order are harry potter and the philosophers stone harry potter and the chamber of secrets harry potter and the prisoner of azkaban harry potter and the goblet of fire harry potter and the order of the phoenix harry potter and half blood prince harry potter and the deathly hallows
Voldemort.
Read the book. There's no easy way to ever explain the Harry Potter series. You just have to experience it for yourself.
Harry lives, Voldemort dies.
The problem in the third Harry Potter book, the Prisoner of Azkaban (spelling?) is that supposed murderer Sirius Black has escaped Azkaban. He was said to have murdered Harry Potter's parents and several muggles. There are more problems, such as Remus Lupin's lycanthropy, but the major problem would be that people think Sirius Black is back to kill Harry Potter.
find out horcruxes and kill voldermort
