put in a new harddisk, I installed windows 7 wihtout any problem. I
could also surf on the internet, but It didn't recognise my windows 7
validation code because it was an upgrade code and not a clean install
So I had to install first windows xp and over XP then windows 7.
by trying to install windows xp, install screen told me that the
partition c: had only 130 gb, while the disk is 500 gb, so I deleted the
C: partition and then the problem begon...
The fan kept on turning and nothing else :) :) :)
So hardware or software fault I don't know...
