My computer restart

[ltyedward]

I'm now having trouble about my computer. The flight sim crash and the computer restart itself when I'm playing (usually small aircraft). However, there will be no problems when I'm playing some add-ons aircraft. What is usually happening? How can I fix it? Thank you. :(

Edward,

We need more info. What aircraft does it happen with? Do you have any add-on scenary in the area? Tell us a bit about your computer, especially what CPU, how much system memory, what video card and how much memory on it? And, just to be clear: What operating system, and FS version?
