My comp doesn´t want to start

[mahesh]

When I start my comp, I get the list with parts in my comp, then the Ubuntu logo, then a flash with a row of messages, and then I am left with the message: /dev/sdaZ:clean, 289358/145222720 files, 55592219/5847288 blocks, and thatś it. I don´t get any further.

What can I do about that?
