After formatting my laptop ClevoX8100 (intel i7840QM - Chipset Intel DMI HostBridge rev.11 - PM55 SouthBridge - 6Gb Ram -  two Radeon hd5870m video card connected with crossfire cable from manufacturer) and install Win10 64bit (from win7 64bit), the bios recognize the correct two video card but when I try to install Crimson software (or catalyst or old software in compatible mode) the install manager select AMD FirePro Control Center, but I don't have a FirePro. Naturally it's impossible to find any mde to enabling Crossfire mode, and in SketchUp drawing app when I try to modify Style and Colors a blue screen appears and report a video driver crash. Windows device manager can only activate the master video card, the other remainsin the devices list with the Yellow conflict icon. Thank you for any welcoming help.
