I think I solved the problem: In the energy options of Windows 7 is a setting which makes the hard disk turn off after a defined time. This time was set on 1 minute, I'm not sure why. So I set this setting to a higher number and there aren't any problems so far.Thanks for the help anyway and again sorry for my poor English.

I don't have the registered version of FSUIPC, but I use the free version. Thanks for the tipp, I will look for the setting.

Thanks for your help! I don't use any SSD.My HD: Samsung SpinPoint HD161HJ 160GB

Dear community,Yesterday, I bought PMDG's 737 NGX. It works very well, but there is still a problem: Every minute or every 2 minutes (I'm not sure) the whole simulator freezes for a few seconds, then it coninues running, after 1 or 2 minutes it freezes again and so on. The problem just occurs during taxiing (on the ground) or during the approach. I think the simulator freezes more often, when I do something in the cockpit of the 737 which is quite complex like starting the wipers. SP1b is installed. Does anyone have an idea to fix this problem?Sorry for my poor English and sorry when there is already a solution for the problem in the forum which I have not seen.My system:Intel Core i7-2600K @ 4.5 GHzAsus P8P67 PRO Rev. 2Gigabyte Nvidia Geforce GTX 5708 GB DDR-3 Corsair Vengeance RAMThanks for reading and the answers!
