P8Z77-V no POST, BIOS or signals

[TBGAPowa]

brand new. everything is plugged in, leds on, fans spinning but no BIOS and POST start up. it didn't come with a speaker so i don't think i could hear any beeps. the monitor, keyboard and mouse aren't getting signals

i am not sure if it was my imagination but i do think i heard ticking sounds and smelled a bit of smoke while installing the cpu and hsf with the mobo placed on the cardboard box cover that came with it. or it may just be the smell of new computer hardware.

the mobo led was on so i don't understand

i can’t trust any technical service with expensive parts, maybe if it was oem i wouldn’t care as much.

IF the CPU LED is on then first make certain you plugged-in both the 8-pin and 24-pin power. IF it's breadboard then do not have it laying on top of an Anti-Static bag! They're conductive.

IF the CPU LED stays 'on' AND you have extra TIM (Thermal Paste) I'd remove the CPU and start looking for bent --- hopefully not burnt --- CPU pins.

The LEDs are a good tell all without the 'beeps.'

Q - What PSU?

I have also had this issue in the past and it was faulty memory.

Intel Core i7 3770k

Corsair AX850

G. Skill Ares 1600 16GB (2x8)

Well the i7-3770K was supported @ first BIOS release. The AX850 - check both leads PSU and 8-pin (i.e. I'd re-seat both ends).

Now the Ares 8GB/stick, might cause a problem but you said specifically the CPU LED.

IF you have a HSF with a metal backplate i.e. aftermarket then once in a while they'll cause a short or grounding short. Therefore, anything metal must have some form of installation i.e. washers or simular insulation.

Sorry, I forgot to ask, what HSF?

 

[JackNaylorPE]

Most common build errors:

1. 8 pin EPS cable not plugged in.
2. CPU fan not plugged into CPU fan header
3. Memory installed in wrong slots

Noctua NH-D14

I'd breadboard; see example - http://www.youtube.com/watch?v=d_56kyib-Ls&feature=player_detailpage#t=1268s

MemOK! led lights up red, what does that mean?

i cant see the cpu led because the hsf covers it, boot device led i believe was green and the flbk led wasn't on.

 

[jaquith]

If the DRAM LED is on it means the memory failed to pass the BIOS 'test.' That can happen for a few reasons:
1. RAM is incompatible
2. RAM is damaged
3. RAM is in the wrong DIMM slots
4. RAM is improperly seated
5. Etc...

IF the ram is touching the HSF it could be shorted/grounded improperly.

In the breadboard IMO try the stock HSF and take it from there.

 

[TBGAPowa]

they aren't touching the hsf, i suspect it may be incompatibility because i didn't see them listed in the manual 1600 list

The Ares should work.

Try (1) stick:

CPU: | -- | RAM | -- | -- |

 

[TBGAPowa]

Or try to clear cmos.

i tried this but still the same result

oh and i will try the 1 stick tomorrow thank you for being so responsive jaquith

SOLVED- i tested the RAM one at a time both were ok, then tried both (properly reseating them this time, doh!) and the red DRAM led turned off the POST splashed on screen and the keyboard, mouse and monitor got their signals. without you jaquith i wouldn't have had a clue on what to do, thank you for being so patient and responsive. and a thank you to everyone else that participated on this matter of mine

You're welcome! Enjoy!

I think ive encountered the same problem. Will try the 1 stick method and post feedback. Thanks for the help.

 

[Ecstasy]

Yes! It worked! I didnt have my ram in properly, you must push it in until it clicks itself into place. I dont know if its like this with all motherboards, but that was my problem. Thanks!!!!
