I've never encountered a crash, ever and I have Laptop, desktop, and game PC built specially for my work and some other works from my early days works too. All these machines I have installed C2. All of them works fine. All these PC has three orating systems on. XP Pro, Win 7 pro, Win 8, Touch wood no crash. Once I had crashed trouble with one machine because it had N****** graphics card and soon as I removed it and installed Re****** it working fine
