New build wouldn't boot. Then it did. Now it won't again.

It sounds to me like it's a BIOS issue more than a CMOS issue. Check Gigabyte's support site and see if the X4 970 comes up on the list of supported CPUs and what BIOS version it requires. If you're still using the factory version you may need to perform an update to get it to work properly.

The 970 is supported under version F1. Would it benefit me in any way to upgrade it to F3 or higher? I'm not sure what AGESA means or how I would update my BIOS if my system won't even power up.

get a speaker for the mb so you can hear the beep codes that will tell you what is wrong

Hey, please excuse my piggybacking on this thread, but I'm going through no-POST issues, and I'm interested in updating the BIOS possibly being a solution.

My PC powers on, fans work, case LEDs work, hard disc spins, but I get no PC beeps (and I have a small speaker plugged into the mobo where it should be) nor HDMI signal output on my monitor.

I do not have an internal disc drive, but rather an external one, and as it is USB powered and my mobo won't POST, it won't open.

My motherboard came with a drivers disk, and I'm wondering if the lack of installing it is what is causing my no-POST issue. Would you think that is a likely candidate? And if so, would buying an internal optical drive allow me to install it even if my motherboard won't POST?

Thank you very much for any feedback, and again, sorry jamestheiii for jumping on your thread with a somewhat different issue; I was just intrigued by g-unit1111's suggestion.

So to be clear, the red light is literally the ONLY thing that changes when you power up, no fans or anything?
