yes in safe mode it doesn't shut down and in regular mode when it shuts down no blue screen
Yes it has a IDE drive.
I changed the motherboard. If it was done in a shop I would have taken it back already.
I don't understand way it works in Safe mode but not in regular mode. I don't believe the hard drive is bad it is a few weeks new and I also ran Sprite on it which found no errors even at low leavels
