Hello and can anybody help me please?I have just assembled a new Athlon 64 3200+ running XP SP2 and a pci express ATI X600 Pro video card. When fs9 or cfs 2 start up (after selecting your flight) ie when it positions you on the runway, either fs9 crashes or the whole computer reboots itself. I have found that if I turn off hardware acceleration on the display adapter that this doesnt happen. I have the latest ATI drivers and Direct X 9.0c I don't know what to do next. The rest of the computer seems to run fine, however windows media player 9 has also crashed the computer twice, but not everytime.Any help would be appreciated thankyouGlennWellington, NZAMD 64 3200+GA K8NF-9 socket 939512mb Dual Channel DDR 40080GB SATA HDDXP SP2FS9.1

Found the problem. Front Side Bus setting in BIOS was set to default. Had to change this to 800Mhz!
