hey all , 10x for answering (I will post hijack log later because this computer that we are talking about billong to him...... ) so we tried to format the computer and it didn't help
there isn't so much programs on the computer
and I`v some knowleadge in computers so I can say that there isn't any strange file on the taskmanager
about the mointor getting crazy, its going on and off lots of times untill it stop and you can back and do your bussiness on the computer..
the computer himself doing some times restart automatcliy (not like the blaster virus you don't have 60 secs, its just restart)
so what can I do ?
p.s
about the 256 mb, windows xp sppouse to work with 256 mb of
ram, even with 64 (slow, but still..) and I did there that the windows will try to use all of the sources only for performance .. so I don't think that it is the problem..
10x: )
