Hello all,
I recently purchased the Crosshair V Formula and an AMD Phenom II x4 955 BE and am unable to get the system to POST. I have 4x4GB sticks of G. Skill Ripjaw Series DDR3-1600 and have tried each stick individually in each RAM slot. Each time, whether I start the system with the power button or the MemOK! button, the CPU Q-LED lights up solid red and the DRAM LED just above it blinks red. The RAM was previously used in another system, so I suspect bad sticks of RAM are unlikely. I have also tried booting with only CPU, RAM, and video card (AMD HD5870) with the same issue. In addition, I've tried the clear CMOS jumper, connecting the 4-pin molex connector, and reseating components, to no avail. I have a 1000W PSU, so power should not be an issue. There is never any video on the screen, as the motherboard immediately goes into the failure state, so I can't say for certain what BIOS version I have (though I suspect it's 0404) and once it enters the failure state, it can only be turned off with the button on the PSU; neither power or reset button have any effect, pressed or held. Short of seeking an RMA for both CPU and motherboard, which I'd prefer to leave as an option of last resort, what other options/techniques can I try to get this board to POST? Thanks in advance.
