I originally sent my e760 in to have the Turbo mod completed. Evga sent me a new board. Upon trying this new board it would power on fans spin then shut off. I resent that board in and got another one problem is this ones doing the same thing. Had no issues with original board. I'm going to swap cpus to see if that's the issue but if it still does this I'm lost as everything was fine. I don't want to have to email another board and waste evgas time or mine. What's the most common cause for this?

Make sure you are giving it enough time, the first post on a new board should shut down after it detects a change from what it was set up as during manufacturing, it may take up to a minute or two, for it to read the new settings, purge the old settings , write the new settings and then reboot. The first time you power up, should take longer than any other boot. I usually put it, in power up, and then go get a coffee of beer, come back sometime latter and see what is on the screen.

Looks like a dead cpu to me.
 

if i pull the CPU will the board still boot but just say no cpu installed?
 
edit: I pulled the cpu and fired up the rig it stays on now and doesn't do the start up shut down, safe to say CPU? Did i do any harm turning it on without a CPU?

either your psu is shot, or something is pulling a leg out of specification, or the CPU is not regestering the voltage presant. Pull as much as possable, see if it boots minimum configuration. if so add componants one at a time until it fails again. if not consider pulling it from the case and booting on a non conductive surface. EVGA may have additional recomendations 1-888-881-EVGA (3842) disregard the error codes, your not on long enough for them to be of any use.

I tried with only gpu having extra power, left all HDDs and cd rome off still no boot. Case is an acrylic board with rubber standoffs.

No, ppls have done this in the past when they were too impatient to wait for the CPU; and panicked when it acted like that. Installed CPU and all was fine. It does sound like a bad CPU, but impossible to tell for sure. GL.

do you guys believe this is a board issue? Without a CPU it stays on but obviously nothing happens, with a CPU on/of cycle. Im buying another PSU just to test but i know this one is current and working

i have 3 sticks in the black slots, ill give that a try here is my run down that i sent evga as i submitted another rma ticket
I tried isolating a short issue by moving to an acrylic case, and even using the motherboard boxI purchased a new power supply to ensure it was not a power issueI purchased a different i7, 920 processor to test and ensure it was not a CPU issueI purchased new corsair memory and same thingI tried with 1 5870 and even with a 8800gt from a working computer still not working

i feel like a total noob, system boots fine now :(
 
sorry for wasting anyones time, especially evga's

now time to see how far i can go under some phase ;)

Good catch, Kram! Belated or not.
