New member
I have Windows 7 Ultimate and I go in to device manager and i have a yellow triangle with a "!" in the middle of it, and it says it can not find the right driver.

How can I fix this? What do i need to install to make this work again?

Regards,
Mark

Hi reptil , Yes you only need to install the AIO driver, :) the missing coprocessor driver is part of the chipset package, If you install windows and only rely on Microsoft to supply the motherboard drivers it will only put on a basic package and that's why you sometimes get the coprocessor error ;)

Okey thank you so much. I dont know how to thank you!.. I wil tell you later when i have install it. And about the other problem when pc starts: Warning Open Case detected is that big problem and can it harm more pc or is just like nothing? Sorry for my bad English. I have read about this Open case detected and Monitor somthing. And it can b fixed on bios and i have read that problem can b fixed to plug or unplug one cabel insside the pc not sure. But never read if that is a dangerus problem or is just like zero problem.

Hi reptil ,The open case is no problem at all It just tells you the case is open ,There should be a micro switch somewhere near the door or side panel that could be wired up the wrong way or you just may have the door/side panel open :D
