Computer Crashes After Post

[AManWithPlan]

Dear Forum,

 

I'll keep this short. I had an AIO pump die on me, it was responsible for cooling my processor with a 2x140mm radiator. The good news was I was working on the machine when it happened, so I was able to diagnose and shutdown right around reaching the 95c limit.

 

I am on the X99 platform using a gen 5 Intel i7 (back when they still made superior 40 lane CPUs), full specs in my profile.

 

After installing a new pump, I think my MBR got damaged on my primary boot drive; but that's ok, I have a USB bootable Win10 drive. Here's the kicker, trying to load from my normal boot drive produces an ASUS logo screen, sometimes with the language "Preparing to repair Windows 10", sometimes without; always freezing on this screen though. Temps are all below 40c (besides vCore temps which oddly each around 57c and make it uncomfortable to touch the heatsink right above the CPU that's designed to cool them, I hope I don't have a short, but BIOS does not crash). There is no overclock on any component in the system. I have the latest non-beta BIOS firmware.

 

The real kick is, when I force the computer to boot from a Bootable Win10 flashdrive, it also crashes, I never get into the future screens. Sometimes it hard resets, other times it just hangs there with the motherboard reading "AA", meaning all good to go.

 

It is bizarre. My next steps is to take out every component and start troubleshooting.

Thoughts?

Sounds like plan. Would start with your massive amount of RAM.

RAM was all good, working for over a year before the pump died. There is no OC at the moment, running it all JEDEC.

I'd check your cpu socket, make sure all the pins look ok.

 

Oh also hell yeah X99 with 40 pcie lanes is where it's at. Best chipset imo, back when the sku numbers and models made sense

I think if I had a seating issue, I'd crash in BIOS or have various other issues which aren't showing up. Worth trying of course, but I don't think it's it.

I meant more for bent pins rather than seating

I am sad to report that even though I caught the bad pump, it has killed my Core #0, #1, #2, #4, and #5. It also likely harmed any potential ability to overclock the remaining core.

I shut them off manually one by one to painstakingly troubleshoot each one.

 

Currently running Windows stable on only #3 turned on in BIOS with the rest off. Also, the uncore is likely damaged.

 

On the brighter side, I found a new 5960x for $445 and ordered it. Hopefully my mobo is ok.

As a follow up, on this single core (2 threads) I have been able to re-write my MBR and thus boot into Windows, rebuild my Raid 0 array, and ensure stability in the remaining Core #3 through AIDA64.

All the other cores are unstable, whether running alone or in tandem. Uncore likely unstable as well (impossible to test with only 1 good physical core). I'm thinking of de-lidding my current broken processor and tinkering with it to see if I can restore some cores to stability. It's worthless on the 2nd hand market, so mind as well turn it into a learning experience.

As a final update to this topic, new processor arrived and everything working smoothly. Never let your processor heat up past 95 degrees, or 106c like mine hit on a few cores; you will irreparably damage them.
