I have FSX (2006) SDX and SP 2 and PGDM 747-400 running on my desktop. :( Sometimes, my system goes down without any warning and not always on the seem momens.When the system start up again Ihave the message: The system is recoverd from a serious fault (free translation ftrom dutch into english).,Some people said: the problem is the SP 2. Before I restore the FSX and other programms such as LevelD and PGDM I want to know is this right? Or what can I do more.Thanks in advance. :( Henk [email protected]

I think the guys in the AVSIM FSX forum might be a better source, but it sounds to me like you have a hardware problem.
