Motherboard Led Code '00' - Unable to Boot

December 5, 2013 at 22:16:47
Specs: Windows 8.1?, 8gb
I'm a rookie to building PCs, and I just recently built one. However, much to my chagrin, it's not wanting to boot completely; can't get to the BIOS or anything. On my ASRock z87 extreme 4 motherboard, I get the debug led code '00'. I've combed through a few solutions on here, but I more or less see mixed answers - I don't believe it is the RAM as I've tried booting without it and placing them in different sockets (however I could be wrong). It is highly possible the RAM is incompatible with my motherboard though....but could that really prevent it from booting?

It's perhaps my Asus R9 280x card that is preventing it from booting, but I didn't think it'd prevent the entire PC from booting (I've tried removing it, with the same results). The reason I say this is because two of the led lights on the card are lit up green to show that it is properly connected, HOWEVER, when it actually starts to boot one of the lights goes red. This may or may not be due to one of the connectors from my PSU being 6-pin as opposed to 8-pin. I am not sure if this card absolutely needs two 8-pin connectors to run.

So could the card be doing this? The other most obvious possible problem would be the CPU (which I know for a fact is compatible with the motherboard), but the fan on it does in fact spin. I've made doubly sure by cleaning the thermal grease off, putting it back on, and re-attaching the CPU.....same results. I don't believe the pins are damaged on the motherboard either, but I will check again later more closely.

The power supply which I am using (and is compatible) is 650w, which I'm told is more than enough power for it, so I don't think that's the problem. What's the deal here?

Other possible relevant information: I'm using HDMI-to-DVI hooked up to the graphic card and I've got the input set to 'HDMI'. I'm hoping this is correct. Will provide any other needed information if you ask me, if I'm missing anything here.

From ASRock support:

00 = Please check if the CPU is installed correctly and then clear CMOS

Did you benchtest the hardware before installing it in the case? If not, that's where you screwed up. Now you have no idea if you have a hardware problem or an assembly problem.

"Will provide any other needed information if you ask me, if I'm missing anything here"

There's a whole lot missing. You didn't list any specs so it's impossible for us to know one way or the other if you have any compatibility issues. Please list the make/model/model numbers of ALL your components.

"I don't believe it is the RAM as I've tried booting without it"

Booting without RAM should cause the board to beep continuously, did it? If not, the problem could be the CPU. Once again, you didn't list the specs so we have no idea if the RAM is compatible or not.

"I've made doubly sure by cleaning the thermal grease off"

Thermal paste must be applied correctly. The desktop Core-i series (assuming that's what you have) uses the "vertical line method".

"I am not sure if this card absolutely needs two 8-pin connectors to run"

If the card has the connectors, they must be plugged in.

"The power supply which I am using (and is compatible) is 650w, which I'm told is more than enough power for it, so I don't think that's the problem."

650W tells us nothing about the quality of the PSU. What is the make/model/model number & amperage specs?

Alright, yes sure, my apologies. I will give you the information; I assumed this might be a problem. Work with me here; I'm new to this. You seem a little pious about it, though sorry if I've read into this poorly.

No, I did not benchtest them. Not even sure I know what 'benchtesting' is.

Anyways, specs are (excuse any unnecessary information):

-Intel core i5 processor (i5-4670k)

-Power supply is VisionTek 650W (this is all I know other than it says AC input is: 115V-230V 10A/6A 60 - 50Hz)

-Video card is as mentioned an Asus Radeon R9 280x.

-The RAM is PNY 4GB DDR3 SDRAM DDR3. (This is the one thing I am unsure about as far as being compatible with my parts).

-The hard drive, if this is even worth mentioning, is Kingston SSDNOW 300, and I am certain I installed it correctly.

'If the card has the connectors, they must be plugged in.'

Right, but it shows the card as having two green lit LEDs when it is powered off (implying that it is connected properly I'm assuming). So the fact that the 6-pin connector did display as green before turning red when booting, wouldn't this still mean that it worked since it was green first? Or is the 8-pin still absolutely necessary? I've ordered one of those cheap 6-pin to 8-pin adapters in case I need it. And still I'd like to know, is it possible for the video card to prevent the system from booting?

'Booting without RAM should cause the board to beep continuously, did it?'

No. It did not beep.

Does this information help anymore at all?

'00 = Please check if the CPU is installed correctly and then clear CMOS'

I saw this, but some others have suggested it could be something else.

If anyone could back to me on this, I would be appreciative. Let me know if there's any more information I need to provide.
