Ultra strange!! Otherwise starting needs to capture the keyboard the blue screen

I start with PS2 keyboard any question, afterward had not had USB.Then blamed
Starting also again could not get up, blue screen or black screen.But I capture the keyboard to be able to open, inserted the keyboard again on OK not any question
Then can tell me for the master is any reason
Has not seen the similar question on-line me
Really melancholy, each time starting must capture the keyboard first!!
