New build doesn't work, motherboard acts weird (M5A97 R2.0)

[Kyphros]

Hi!

I just built a new PC with both new and old parts, and it doesn't work. First, the config:
Old (works for sure):
HD 6870 Sapphire (GPU)
2 HDDs
1 DVD reader/writer
Antec Three Hundred (Chassis)

New:
OCZ 750W PSU
FX-8350 (AM3+, 4Ghz, 8-core)
Hyper 212 EVO (CPU fan)
4x Corsair Vengeance DDR3 4GB 12800
And, lastly: ASUS M5A97 R2.0

My problem is that absolutely nothing is displayed on-screen. No POST, no BIOS.
Furthermore, when I press the "on/off" button of my chassis while the computer is booting, it doesn't shut off. EVER. The only way to shut it off is to use the PSU's switch.

I have tried:
- Updating the BIOS with the integrated function that allows me to update without a working cpu. Because it could have been its fault since the CPU wasn't supported in the mobo's early BIOS. The update was successful. Twice.
- Clearing the CMOS.
- Unplugging and re-plugging every single one of the PSU's cables
- Unplugging and re-plugging the chassis' cables.

No luck, nothing changed.

I also tried pushing the MemOK! button. All it does is make the light flash during a second, every 2 seconds. FOREVER. Without actually doing anything, or so it seems.

Since I have never seen that before, I'm not sure what to do. Is the motherboard defective?

Thanks in advance.

try booting with 1 memory stick, in varying slots, with your hdds and cd drive unplugged

also you did plug in the 8 pin power at the top right?

Sir,

This is what I would try.

Swap know good components(old) while using new components. Try the PSU first, then I would try the motherboard, seeming that this would take longer to check. If you had a failing component besides those usually a POST error would result. I'm guessing it's either the the MB or PSU. Best of luck.

Well then, I'll try that.

I'll try that.

Yup.

I just tested everything, and it all works except for the motherboard. Problem solved, then. I'll have it replaced. :/

Good to here you isolated it. I had an old 670i board that gave me errors when I first got it. Newegg was awesome with their RMA procedures for me. Cheers, enjoy your build when it's up and running
