Interesting, I had no idea about that. I decided to test it with just the 4 pins and it performed the same. Please note, the CPU stays cool throughout the process. Initially, I took it out of the case and tried to boot without its GPU or storage devices, keeping everything simple. Both the 3570k and the Celeron 460 models I purchased for testing have integrated GPUs, which I'm using to check for PCI-E or GPU problems. I've also tested two confirmed working power supplies, though I haven't changed the RAM because the board shows a RAM issue LED that isn't lighting up.
I'd examine your VRM's performance. If the chip remains cool when you attempt to power it, it suggests an issue with the power supply. If you're willing to go further and have a multimeter, you might test the resistors on the CPU socket to check for voltage. My idea is that you're not receiving any voltage to the CPU at this stage.
If you have any recommendations for a guide on testing the VRMs, I’d definitely want to check it out. I enjoy tackling these kinds of challenges and learning new things. I’ve used a multimeter to help with audio installations in my cars, repair a 3D printer, and fix aftermarket turn signals on my bike. I’ve marked the board here, marking what I think are the VRMs for the CPU. It seems like probing those larger pins in an L shape might be the way to go. I’m still a bit unsure about the exact pins involved.
Thanks for the guidance on reaching this conclusion. It helps to discuss concepts with others. I plan to look for someone who can clarify things, possibly updating the thread if needed. It would be helpful to move beyond vague statements like "the board is dead" and instead pinpoint failures, such as "the VRM failed." Understanding the reasons behind issues is always valuable.
Did you finally understand this problem? I thought the other board was the cause, but it might be the PSU or CPU instead.
