OK, so I just bought a lovely new system. It's great on paper, but unfortunately it's not doing much right now! I've built about 4 or 5 systems in the past without any hassle I guess, apart from maybe the odd processor cooler that caused me some headaches. The Rampage Extreme is definitely the most expensive motherboard I have ever purchased. Unfortunately, it will not boot. OK, so it boots to a stage, then just stops. I would like to know if you can suggest anything for me? The interesting thing is that the system does not boot at all when a USB keyboard is connected. Obviously I need this USB keyboard in order to configure the machine. When the keyboard is not inserted, the system boots successfully and completes the POST test. However, it cannot find a device to boot with and asks me to press a key to restart. Of course there is no keyboard connected. When I connect the keyboard, I cannot press any keys. It is as if this motherboard just cannot use a USB device! Needless to say, I have cleared CMOS and tried rebooting many times but I get the same problem each time. Has anybody else had this problem? What can I do?
