CPU LED POST error on Asus P8P67 Pro

[nickyD]

Build:

Intel Core i5-2500k
Asus P8P67 Pro Motherboard
4gb patriot ram
Using a non-stock thermaltake CPU fan
850w thermaltake power supply
1.28MB Nvidia Geforce GTX (PNY)

Problem exists between the motherboard or the CPU (OR THE USER!

When I post the system (with only RAM, CPU, Power supply installed), it turns on and throws a red LED which indicates that the CPU has an issue.

I unseated the heatsink and pulled the CPU out of the socket to inspect the pins. I didnt see even the slightest damage. Reseated the CPU, still posting to CPU.

Only thing I noticed was a slight smudge of thermal paste that was overlapping the silver casing of the backside of the CPU, spreading a little toward the PCB, but there was no trace of it smudging anywhere near the conduits on the operating side.

Tried reseating the ram (I was only using 1 stick to POST) and ensuring it was in the blue seat.

After a 30 mins or so of google search, I hear people saying that when they inspect the seat it has damage to pins or there is thermal paste between the pins and the seat...but I dont have any of those issues.

ALSO, there is a EATX12V 8 pin connector on the top orientation of the motherboard that i have left unplugged. I think this MIGHT be the reason, but some say you dont need to connect it for some configurations (especially in post) if Im not overclocking. I WOULD HAVE plugged it in, but it seems like there is a 6pin + 2 setup on my power supply that has a slight lip on the bottom (where the 2pin connects to the 6 pin to make 8) that prevents me from putting it in. Id rather ask than file the lip down to make it fit and blow up my computer...just wanted to mention that this portion is NOT connected (and if I need to, do I have to make a trip to the store to get the proper adapter?)

Any ideas? Thanks! Trying to get this gaming rig done tomorrow on my day off before my brother takes off for school on Friday! Ugh!

If I do have to take the motherboard back because it's defective, that's fine because there is a brick & mortar store about 10 mins away where I bought all this stuff.

This is my 4th computer to put together and Ive usually had pretty simple and easily fixable issues upon POST, but never anything having to do with CPU!.

Shoutout to glc , if you're still here! You helped me way back when I was building my first computer about....10 years ago!

You'll need to plug in either a 4 pin, 4+4 pin or 8 pin CPU power connector at the top, the one you mentioned was unplugged. Your computer will not start properly without that plugged in, 6+2 pin are for PCI express (usually video cards) and is not the proper connector. If you are still having problems after connecting the cpu power connector, try resetting the CMOS, but as far as I can tell right now, you should be fine after connecting the cpu power connector at the top.

I attempted to plug in a 6 pin from my power supply. When I do so it doesnt boot up at all (i think because it lacks sufficient power).

I dont see any 4 pin or 8 pin connectors in the power supply box, which I think is kind of strange...


is FRYS.com*|*AMERICAN this what I need

[glc]

No, you need a power supply that has an 8 pin or 4+4 pin EPS/EATX connector. Do you have a link to your exact PSU?

Is this it?

Newegg.com - Thermaltake Black Widow W0319RU 850W ATX 12V v2.3, EPS 12V v2.91 CrossFire Certified 80 PLUS BRONZE Certified Modular Active PFC Power Supply

If so:

1 x 24-pin Main Connector 1 x 8-pin Power Connector 1 x 4-pin Power Connector 7 x SATA 4 x PCI-E 7 x Peripheral 1 x Floppy

It will be part of the main harness, not one of the modular cables.

No it's FRYS.com*|*THERMALTAKE this one...

I see on the box that it does say it has a "NEW" EPS 8pin Connector (with 8-pin EPS connector to support latest intel processors)....I havent seen that yet. Let me try and sort out the wiring...

let me see if I can find that.

Great. Booted up nicely. Thanks!

No hard disk detected upon boot up. It has power and is connected to the SATA port...

[glc]

Which exact SATA port is it connected to? Is it a SATA 3.0 or 6.0 hard drive?

[nickyD]

Looks good! Hard disk boot failure was due irrelevent. I was just using one of the 3 types of hard disk ports...

[glc]

It matters what type of drive you have and which type of port you use.
