Hi, and thank you for your answer.
I will have a look in the computer to see if the support of the motherboard
seems ok, and try to start the computer with the original DVD next time I
shut it off. If none works, I'll unplug everything and plug it back one by
one to see if it comes from another part of hard ware. I have also be told
to change the battery so I'll try it too. I'll let you know how that goes as
soon as it is done. (It is possible that I don't do it before a month or so
except if the computer is shut off by accident)
Thank you for your answer
