I5 10400F pc dos not turn on

[Josep]

Hello

I have problems with an I5 10400F processor that mounts on a pc and does not turn on.

Asus Prime H510M-D Motherboard

Asus Gforce GT 1030 2GB GDDR5 graphics card

Looking at the processor from behind it looks like a weld pin is missing in the second row upper left corner.

Could that be the reason?

Greetings and thank you for the answer.

Hello @Josep

Thank you for posting on the Intel® communities.

In order to check this further and regarding the screenshots about the "possible missing land pad" (gold connector), could you please provide the following information?

1- What steps were taken to troubleshoot this issue? Did the processor work fine before?

2- Is this is a new processor and/or system? If yes, was the processor purchased less than 30 days ago?

3- Did you have the processor in this condition since the very first day that you received it? Of did you find out this after some time using/installing the processor?

4- Make, model, and part number of the Random Access Memory (RAM):

5- When you say "pc does not turn on", do you mean it is not powering up at all? (Not even showing any led on the motherboard?)

When it comes to not boot/no display issues, usually, the motherboards have a series of onboard debug LEDs or beep patterns that may help to diagnose what could be the problematic component.

Could you please confirm if you have verified/tried this with your motherboard?

Note: We tried to find more information about this by checking the PRIME H510M-D User’s Manual ( English Edition )*, but we couldn't find details about "onboard debug LEDs" or "beep patterns". We suggest checking this further with ASUS* Support for more details.

6- In order to discard other causes for this issue, could you please confirm if you have tried the following steps? If you haven't, could you please try them and let us know the outcome?

6.1- Try to clear the CMOS:

• Start with the minimal hardware in your system, such as power supply, one DIMM of memory, and the external graphics card.)
• Clear the CMOS (complementary metal-oxide-semiconductor).  Check the instructions on how to clear the CMOS.

6.2- Determine if there have been any recent changes like BIOS updates or hardware changes:

• If there were any hardware changes, revert the changes.
• If you made any BIOS changes (including flashing it) and your system stopped working, revert back to the working BIOS. Contact your motherboard vendor for information about reverting your BIOS.

6.3- Check main components:

• Ensure the processor is installed properly.
• Check if you have properly applied thermal paste.
• Ensure the fan heatsink is installed properly.
• Ensure DRAM is seated properly depending upon if you have two or four DRAM Memory Modules.

6.4- Other steps to review:

• Check if front panel header connector is firmly plugged into the board.
• Since this processor does not come with integrated graphics, have you tested with another external video card? Or have you made sure your Asus Gforce GT 1030 2GB GDDR5 graphics card is properly working? (for instance, by testing it on another working system?)
• Check cable connections for: monitor, power supply, and fans.
• Check the monitor for video input selection: VGA, DVI, HDMI, or USB-C.

Also, in regards to your original inquiry about the "weld pin missing", we would like to inform you that a damaged or missing gold pin/connector could affect and be the cause of an issue like this one. In the following link, there are some examples of Physical Damage Due to External Causes on Intel® Desktop Processors, a couple of the examples in that article might be similar to what you see on your own processor.

Please do not hesitate to contact us back if you have additional inquiries, and in that case, please kindly provide us with the information previously requested.
