Having Booting issues - No POST

[commandosqueak]

Hi,

Sorry if this is in the wrong section, I wasn't sure where to post it, please feel free to move it.

Recently got a Macbook and in doing so my gaming rig has been neglected (not used) for the last six months. I decided today to boot it up and update everything and maybe play a couple of games. Well I guess neglecting it for six months it's decided it doesn't like me any more. Last time I booted it, it worked fine without any issues.

When I try and boot I get no POST so It suggest a hardware issue rather than OS. Motherboard G code is 00 (not used according to the manual). The hardware itself should be fine it worked properly six months ago its just not been turned on since. I have tried reflashing the BIOS but no change, tried various different versions downloaded directly from the manufacturer. I have noticed the fans are not spinning although the AIO Water cooler seems to be running the pump. I don't want to run it for long as the fans are not spinning to cool the water. Tried safe boot tried the 2nd BIOS. Tried the MEM OK button and the reset and slow boot.

I have had a recent hardware change. I swapped out the DVD drive for an ASUS Blue-ray drive. It has booted several times since this change with no issued. Just to rule it out I have unplugged the drive but still have the same issue.

I have removed all peripherals and non crucial drives and still have the same issue. Tried clearing the CMOS.

Not sure if its relevant but just to the left of the 7 segment display is four orange LED's. The bottom one flashes 10 times, half a second on half off, then the bottom three lights come on and a red LED under the power supply connecter (labeled CPU_LED) for half a second and the sequence repeats.

It's all pointing to a CPU issue but I don't understand how its suddenly not working.


My hardware is the following running at stock speeds and no overclocking:

Rampage V Extreme Motherboard
Intel i7 5930k CPU 3.5GHz 6core
16GB Corsair Vengeance DDR4 Ram 2400MHz (4 * 4GB stick in slots A1, B1, C1 and D1)
MSI Nvidia 780GTX Gaming edition (6GHz ram rather the 3)
Corsair HX1000i PSU
Hauppauge WinTV-HVR-5525 TV tuner
TPM module
Asus Blue-ray drive
ROG Overclocking panel that comes with the board
CoolerMaster AIO water cooler on CPU (no leaks or signs of leaks)
Several hard drives of varying capacity and a Sandisk plus 480GB SSD as the boot drive.
And of course not complete without LED fans and LED tape all packaged in the Corsair 780t Case


I have completely stripped, cleaned (was bit dusty and due for a clean) and reinstalled all components. Including CPU and RAM. All pins are pin and CPU in correctly.

Still coming up with CPU error light and G Code 00. Double checked all cables are plugged in correctly.

I'm at a loss now, would appreciate some input. Unfortunately I have no other compatible hardware to swap and test components.

I think you have a problem with the graphics card. What do you have in each of the PCIE slots?
Verify that it is firmly seated and verify the output to the monitor.

You mentioned that the fans are not running to cool the AIO. Are they connected to the motherboard, or by molex connector? If the fans are not turning on and they're plugged into the motherboard, that leans me more towards either the motherboard or power supply having an issue? Has there been any lightning storms or brown outs during that 6 month period?

Does your motherboard support beep codes? Thats kind of old school, but if you've got a 2-pin speaker lying about you might be able to get an idea of where it's having issues by the beep code.

Hi Thanks for taking the time to reply. Initially I though the CPU fan wasn't running but since posting I realised it was. The CPU fan and Pump are plugged into the motherboard with the standard fan plug to the cpu fan and cpu optional connectors on the board. The pump and CPU fan run but none of the other fans are running. All fans are plugged into the motherboard and each fan has its own connector, none are daisy chained. There has been a couple of power cuts but nothing when the machine was on. There has been lighting storms too, however my computer including anything connected to it are plugged into surge protectors and I tend to unplug my sensitive equipment during lightning storms as I have a lot of radio equipment ect. Unfortunately I don't have a speaker to plug in that I know of, I will have a rummage in my old parts and see if I have one hiding somewhere. The motherboard has led's that do this job plus a seven segment display which shows an error number.

In terms of the PCIE slots. My graphics card is plugged into number one which is a 16x slot and all the other 16x slots are empty. The 1x slot has the tv tuner installed.

I have managed to find a speaker. when put one way round there is no sound. When put the other its just a continuous tone, like when someone flatlines. Oh the irony haha

It's sounding more and more like the problem is motherboard specific. Are you able to take the motherboard out to verify that there's no standoffs in weird places causing a short? If the display shows an error number, have you checked the motherboard manual, or googled it? You could also try the graphics card in a secondary PCIE slot as well, but I don't think that's the issue. However it'd be nice to at least rule it out. I'll post again if I can think of any other things to try.
