Welcome!
I have problem with my mobo, Asus Crosshair Formula Z.
I turned off my computer yesterday, like everyday.
Today turn on and... nothing. Computer doesn't start.
I've checked error codes and:
code 66 - PCI host
code 68 - CPU DXE
code C5 - OEM BPS
in random order.
Mobo wasn't overclocked, don't changed BIOS.
What is wrong with my mobo?
Crap or repair?

Spec:
CPU: AMD FX 8350
RAM: Patriot DDR3 Viper 1x8GB
GPU: ATI HD7970 MATRIX 3GB
Hard Disk: Crucial MX200 SSD 250GB
Power: Chieftec Nitro 1000w 88+
Sound: SB X-Fi Titanium Fatality Professional

Best Regards

Maybe try another power supply?

I had a similar problem that I misdiagnosed on my Formula Z... turns out it wasn't the motherboard at all. The graphics card was not displaying video.

Prior to figuring that out I was heavily overclocked, then used defaults, flashed BIOS once or twice, and even ordered a new BIOS chip. Board was fine the entire time though, and now I even have a heavier overclock on my 8350. No problems.

I'd start my troubleshooting by clearing your CMOS. Then testing your power supply by doing the paperclip test (or maybe your PSU came with a little tool to do the same thing). Just watch a video on Youtube on how to do it.

If the PSU works, remove your hard drive and if you have an old one to try, put it in to see if your Crucial drive is at fault.

Yeah unplug the hard drives and physically remove the sound card leaving only a single stick of memory and the graphics card. You want to narrow it down and slowly start putting one part back at a time.
