Some information about working with surface mount devices here:

If you don't have appropriate soldering equipment and experience, the main risk is damage to tracks and solder pads on the board.

If you can identify that one of the transistors is shorted and preventing the board from booting up, eg by measurement with a meter, but don't have soldering equipment, you may be able to carefully cut the transistor leads using a brand new blade in a Stanley knife. That could achieve Lex's second repair alternative.

Thank you for your quick answer - i am reading now - not to destroy to much.
I probably use a blade, but I wonder about the glue under the smd transistor. But it can stay on its place with cuted leads, in the end.

Victory, I have fixed it 15 minutes ago.The machine is still alive. I am writing this post on it. I cutted off the Q21 transistor (next to front USB connectors on mobo) and it was that. Thanks a lott LEX, Platypus! and other people for help!
