So I just bought a bunch of computer parts to throw together for a friend, but I ran into an issue when finally trying to turn it on...

The motherboard goes through its standard system check up and when it hits the last light on the motherboard, the "boot_device_LED", it beeps five times and stays constant. There is no visual on the monitor to help me out here, the only thing I have to go off of is the beeps and the light.

I've made sure everything is connected properly and I've kinda ran into a wall here trying to get this work. Does anyone have any ideas? thanks a guys.

I would but the problem is that it fails the start up sequence before that happens, and there is no display.

so after you power up the video never comes on?

Get the motherboard manual out and read it.

Also are you sure you have the video cable on the video card or the IGP itself

I did but Asus doesn't describe what the "boot_device_LED" means and looking it up through google is getting me different scenarios that doesn't relate to me.

I'm not sure what you mean by the video cable.

Okay so I took out a ram stick, put the video card in another slot, ANNND resetted my CMOS. Now the display is back up and running. Although, I'm not sure why but it is giving me a "CPU Fan Error!" Even though the fan is clearly running. Why is that??

You may have the CPU Fan on the wrong header. There are 2 right beside each other. I made the same mistake on a recent build I did for a friend on a Z68Pro/Gen 3. Just put it on the header and that should solve that problem ;)

I just checked the wires again and I noticed I put it in the wrong CPU fan, everything is now working perfectly! Thanks for all your help!
