Hi there,i've installed FSX now for about 2 weeks on a brand new system, but it freezes randomly, without doing nothing particular. It freezes when flying 'offline', it freezes when flying default planes, it freezes when flying payware planes (like LDS 767X, PMDG MD11X), it freezes when flying at night... I have no idea why it freezes :( .Sometimes it freezes after a few minutes, and other times it freezes after more than 30 minutes.There is no particular action that initiates a freezing of FSX. The screen just freezes, and I have to start the Task Manager to quit FSX. (saying: is not responding)I use FSX with Acceleration Pack, FSUIPC4 4.53, IvAp/FSX v.1.9.8, Active Sky X, XGraphics, PMDG MD11X, Level-D B767X. I always fly online with either MD11X or 767X.FSX is installed on a secondary hard disk 'D:'My system:Windows Vista Home Premium 64AMD Phenom II X4 955 Quad Core 3,2 Ghz6GB memorySapphire HD4890 1GB graphics cardI already tried to re-instal acceleration pack, the FSUIPC4, IvAp/FSX and I installed the previous display driver from AMD/ATI v9.8 - all without any result.Can anyone help me please?Thanks a lot... :(
