Recently I've swapped my Intel stock cooler to a Noctua NH-D15 and it worked wonders for several days, until the PC started to not boot and not show any debug LED codes, except for when it would actually start to show booting debug LED codes and it would shut down on the debug code 78 (ACPI core initialization). Few months gone by since the issue started, I noticed that the PC would actually boot, but only when I leaved it with the PSU power cable not attached to the wall plug for some days (like 3 or 4 days), so I thought it was a PSU issue, then I bought another PSU and installed on my computer, but to no avail.
I filmed the issue and it is in this YouTube link: https://www.youtube.com/watch?v=jdxr7NU_Brw
Things I tried:
- Changing the PSU to a new one.
- Remove the BIOS battery for several minutes and putting it back on.
- Reseating the Noctua NH-D15 cooler.
- Booting with 1 RAM stick on different slots
- Booting with onboard graphics instead of GPU
Things I have not tried yet:
- Reinstalling the CPU (maybe one of the pins bent while I was installing the Noctua for the first time?)
- Try to boot with the mobo out of the case (don't know if this works)
Also, I should add that when the PC booted, I would occasionally get a random BSOD that had a "WHEA_UNCORRECTABLE_ERROR" error. Unfortunately, I don't have the dump files available right now, but I'll post soon as I manage to get it.
Thanks for all of you good folks here in the LTT forum in advance! Help me get this Christmas miracle this year xD
