Amd Athlon 3200 2.2 ghz 512 ramI have been having hard freezes. Just installed fs9. So I am a new user. I have flown for hours at a time and had a crash in as little as 1 minute. I tried a ATI 256 graphics card and the freezes increased. It would fly for about 5 to 10 minutes then freeze, consistantly. I have been working with a computer shop and he just insalled the Gforce 5500 also a new clean hard drive. Things are working well he says. But he says the next step is to reformat and return my original hard drive in the system. I hope this works.I worry about when I bring this home and start to load my other software back into the system. I will take it slow so if a problem I can identify the program that my be the confliction.I hope we are barking up the right tree. I bring my computer back from the shop tomorrow. Can't wait!!I would like to point out that most frequent crashes could be brought on by going to the alternate view that lets you look around the cabin.I like this view for patern work. Please let me know if anyone else is having these problems.

I had a similar problem to you,and it turned out that my memory was overheating at 400mhz.i used 1gb of Ballistix 400hhz memory.the CTD could happen 1min or 45min into a flight,after 3 or 4 months of messing around i read on here about a similar problem and turned the memory down to 333mhz.Bingo...no more crashes.it turns out that ATHLON CPU's don't like certain memory chips.and this was the problem.if you look on the web.companies like Overclockers sell memory specifically for Athlon cpu's.in the mean time i had spent nearly

Steve,I am experiencing freezes which require a cold boot. I am also using an Athlon processor and 400Mhz memory. Since an overheating problem is one possible cause, I was curious about how you can reset your memory to 333Mhz. Isn't this hazardous to the health of the PC?Thanks!Airbus
