D945GCNL no boot, post code 25

Spec:

CPU: E4400

Board: D945GCNL

Memory: KVR667D2N5/1G *2

This computer was working fine.

But one day, it has no display suddenly.

I tried both memory and cpu on other board. They work fine.

Now i just installed the CPU, one memory on first slot to try to boot up.

But it returns post code 25.

I have tried to unplug the BIOS jumper ,recover the BIOS by using NL0036 / NL0005.

But because no display, i don't know how its process.

After a long time ( ~15 mins). I shut it down and plug the jumper back to config mode and turn it on, but still no display.

So what can i do now???

Hello momoegg,

We would like to inform you this motherboard has been discontinued but here are our recommendations for this issue:

- Proceed to test the motherboard on a minimal configuration out of the chassis

- Test the system without memory looking for beep codes

- Test with an external graphics card to narrow the issue properly

-Clear the CMOS battery for 30 minutes and proceed with a BIOS recovery test:

I am testing the motherboard on a m minimal configuration only, motherboard, cpu and one ram.

 

 

- Test the system without memory looking for beep codes

It has three long beep if without memory.

 

- Test with an external graphics card to narrow the issue properly

The issue remain same, no display at all, post code 25

 

-Clear the CMOS battery for 30 minutes and proceed with a BIOS recovery test:

Did it few time, still no use.

Hello,

You may want to try a BIOS recovery to version 0033. Remember to download the bio file and remove the BIOS jumper. Download Center

If you continue having the same behavior, feel free to contact your local Intel support group for assistance on replacing your product if it is still under warranty: http://www.intel.com/p/en_US/support/contactsupport?group=processor http://www.intel.com/p/en_US/support/contactsupport?group=processor
