hi efabes, just wana say thanks 4 al ur help n advice u hav given me.
i found out earlier 2day that my computer has been fixed and everything is working properly, so it is now ready 2 b used again.
They told me that they tried installing the cleanest possible version of Windows ME they have, but that didnt solve it. They tried installing Windows XP, that didnt solve it either. Half of the Windows XP package refused 2 load.Then they took out the motherboard n put a brand new one in, n hey presto !!!! computer was working.
Turns out that it was all down 2 hardware, n my computer is finally working properly !!!!
