I5-14600K not posting on new build

[KrankyKoot]

New build will not post.  Power to cooler fans and some lighting but no video and power light just flashes.  Same for 2 motherboards from Asus and Gigabyte.  Tried disconnecting everything except bare min.  Video is HDMI to I5.  Chip is seated properly and I have tried reseating.  Do I have a bad CPU?

Hello @KrankyKoot,

It sounds like you've been through quite a journey already with this build! Dealing with a flashing power light and no display is definitely frustrating, especially after trying different motherboards and double-checking your seating. While it can be tricky to pinpoint the exact cause in a new build, there are several common compatibility and configuration steps we can look at to get your system up and running.

To help you troubleshoot, please take a look at this official guide:

How to Fix Issues With No Boot or No Display for Self-Build Systems With Intel® Processors

 

Key areas to check while troubleshooting:

• The Flashing Light: Usually, a flashing power LED is a specific diagnostic code from the motherboard. We recommend checking your motherboard manual to see if that specific rhythm indicates a memory configuration or a power delivery requirement.
• Listen for Beep Codes: If you have a motherboard speaker connected, the patterns of beeps provide vital diagnostic information:
  • 1 Long, 2 or 3 Short Beeps: Usually indicates a video/graphics initialization issue.
  • Continuous Beeping: Typically points to a memory (RAM) error or seating issue.
  • 5 Short Beeps: This can mean the motherboard is having trouble communicating with the processor, often resolved by a BIOS update.
• BIOS Version: If your board features a "BIOS Flashback" button, performing an update via USB is often the quickest fix.
• RAM Check: Try booting with just one stick of RAM in the primary slot. This helps rule out any minor memory timing or compatibility hurdles.

To help us narrow this down further, could you please let us know if any other processor was used in those motherboards and if they worked? Knowing if the boards have successfully posted with a different CPU can help us isolate the issue.

Please give those steps a try and let us know if the behavior changes. We’re here to help you get your new Intel system up and running!

Warm regards,

No this was the only processor in a brand new case and mb.  No beeps on very old mb speaker.  No Asus MB status leds.  Only fans operating are the cooler fans and assume the water cooler.  Case fans were initially installed but did not spin.  Fan RGB lighting also worked.  I did a minimal install removing RGB, case fan, usb, and audio headers.  No bent pins.  First MB was a Gigabyte board with standalone BIOS USB and it would not start the update.

Hello @KrankyKoot,

Thank you for the detailed troubleshooting and for trying the configuration across multiple motherboards. Based on the steps you’ve already performed, including minimal configuration testing and reseating components, the issue may be related to the processor and would require further validation.

At this point, we recommend proceeding with a warranty request for your Intel Core i5-14600K. Please submit your request using the Intel Warranty Center:

https://www.intel.com/content/www/us/en/support/warranty.html

We will continue assisting you through the warranty process via email.

Warm regards,

Hello @KrankyKoot,

Thank you for the update, and I truly appreciate you taking the time to share your plan.

Since this matter has now moved forward as a warranty replacement request, it will be handled directly under Intel’s warranty support process. As long as the product markings and required details are verified successfully, the warranty team will take care of assisting you with the replacement.

Because of this, the issue is no longer within the scope of community-based troubleshooting. I would kindly recommend closing this thread at this point.

That said, you’re always very welcome to return to the community if you have any other questions or need assistance in the future - we’ll be here to help.

Wishing you a smooth and quick resolution with your replacement, and I look forward to hearing your update once you receive the new unit.

Warm regards,

Manas Sharma
