I have a rampage 2 extreme motherboard and a vigor monsoon 3 lt heat sink. This just randomly started but it says CPU fan error whenever I boot and says hit F1 to resume. After I hit F1 it takes a few seconds and says error: no such device (and then a huge ass code) and says grub rescue> beneath it.. I've disabled the CPU fan monitor in the BIOs, completely took the fans off and cleaner out the heat sink and still yet CPU Fan Error.. The fan is clearly working. Is there a command to bypass this and boot up windows? Please help, thanks.
