Please provide more details. Is this a new build or did this problem develop over time? If so, what happened (what changed)? What is the last POST code you see? Can you provide the complete list of POST codes you see?

Hi Cr4zYn0u,

 

 

I am following your case; please include the brand name and model of the memory to Scott's request.

Did you see the problem immediately after (i.e. as part of) installing the BIOS update or was it working fine for a while afterwards and then the problem occurred?

What is the last POST code that you see?

Is the on-screen POST code display disappearing or does it stay on the screen?

POST codes in the 0x10 - 0x1F range are indications of steps in the initialization of the processor and direct peripherals (including memory). If the problem is occurring here, it is usually an indication of a processor or board/memory failure; it is typically not anything to do with the BIOS update process.

One thing you can try is to power off the system, unplug it from the wall and then remove the CR2032 battery from the board for 15 minutes. This clears the CMOS memory. As you power on, use F2 to enter BIOS setup (if it does not take you there automatically as a result of the CMOS clear) and then use F9 to reset the BIOS configuration. Make any changes you need (boot order, etc.) and then exit from BIOS setup with a save.

Hope this helps,

...S

Hanging at POST code 15 usually means that there is a hang on the SMBus. The BIOS needs to use the SMBus to read the SPD data from each of the memory DIMMs (which tells it how to configure the memory). I have seen this issue caused by a bad (failed) DIMM. I suggest that you try using the board with different memory and see if the problem is resolved that way. Alternatively, remove all but one DIMM and see if that resolves it (if it does, switch to each of the other DIMMs one at a time and determine which is bad)...

Hope this helps,

...S

Did you try testing with alternate memory or testing with (only) a single DIMM installed as I suggested? Don't scream for help if you won't follow the guidance provided...

Hi Cr4zYn0u,

 

 

Have you tested your PC using motherboard, cpu and 1 piece of memory DDR3 1333/1600MHz at 1.5v without the external graphics card

Hi Cr4zYn0u,

 

 

You already performed all the basic troubleshooting without any succeed. I recommend you the replacement of the board. Intel provides with 3 years of warranty since the date of purchase.
