No beeps/post, PSU fine.

I recently did a new build with-
M5A97 Pro
FX8320
HD7870 black/tahiti
8GB (Single) Corsair vengeance
OCZ Agility 3 SSD 120GB
Toshiba laptop HDD 160GB
Seagate Barracuda 7200.12 500GB
Seagate Pipeline HD.2 500GB
OCZ 500W CoreXstream PSU
Powercool Barracuda case.

When turned on, the DRAM LED and CPU LED flash for a second and then go off, which I presume means they are fine, the motherboard power LED is constantly green, all the fans spin up and the CPU area gets hot after a few minutes. However, nothing appears on the screen, and there is no beep.
At first I concluded it was the PSU using this sites guide, but after putting it in an older PC I found the PSU worked fine, what else could the problem be?

1. Are both the 24-pin motherboard and 8-pin CPU power connectors plugged in properly and secured?

2. Is the RAM module not dead?

Did you make sure the standoffs are in place under the MOBO.

I had the same problem when I did not plug power to my GPU. I then got the power plugged in to my GPU and it worked.

I had the exact same issue!!!! I had to keep it to basics.... . Sometimes its best to walk away from it and take another approach to it after a deep breath.

1 - Double check the stand-offs are installed right with the motherboard like the other suggestion, and the cabling is all plugged in securely. Power and so on.

2 - My solution was - Remove and re-apply the heatsink/power cable when i had this issue. I gave it the ol 1985 NES blow, no lie.

If that does not work, that bios is out of date for that new CPU (unlikely, but a possibility)

These other guys have good tips, but mine was installed right, Just a removal and/re-applying the heatsink ...Try it.

After rethinking everything, I'm now fairly sure it's because the BIOS is outdated, I bought the standard M5A97Pro rather than the R2.0 model, and put in a Vishera CPU, so I guess I'll have to borrow a CPU from someone.

I know it had no problem with motherboard power/DRAM modules/VGA because the motherboard lights for each piece showed they were fine.

I'm fairly sure I put the standoffs on all correctly, as well as the heatsink/power cables, but I'll try it anyway.

Yeah, sometimes that can be a over-sight for sure.

Thats why i suggested it as a long shot. There may be options direct from asus support, to mail you a different CMOS/BIOS chip to replace with an updated version. Although i never would attempt and for sure would be faster just to take it to a shop, have them stick in a different CPU update it for you, or borrow an older one as you said and do it. You can call a shop and ask how much they would charge for this... vs the hassle of doing it.
