Brand new computer. Athlon 1800+, Geforce TI500, Windows XP, all bells and whistles. Start up Flight Simulator FS2002. Wow! Go to bed late, but happy bunny. Next day, start up again. Fly a while. Suddenly screen freezes, blacks out. Reboots: "System has recovered from a serious error. Possible device failure. Driver for Geforce seems to be responsible for system instability." Gee, doc, thanks for the diagnosis - but what's the cure? Error report to Microsoft, awaiting reply. So what's going on? Driver is 21.83, allegedly optimised for XP. Can anyone help? Consensus in flight sim community seems to be that 12.41 is most stable. Would that help / be compatible with XP? Advice would be much appreciated by this very frustrated virtual pilot.
