Home Circuit Breaker Failure Caused Unraid Failure

 My Unraid server died 12/23/2024. The power went out twice. Bad shutdowns. UPS did not last. Power stayed off until circuit breaker replaced in house.

12/24/2025 Attempted boot. Kernel Panic Error.

Rebooted. bzimage checksum error.

Rebooted. Entered BIOS. Corrected the boot order to USB drive first.

Rebooted. Reached Unraid Boot Menu. Started MEMTEST86+ at Unraid boot menu.

Failed MEMTEST86+. To do.

1. Created new bootable USB from Windows with newest free version of MEMTEST86. I ended up using Rufus to create the bootable usb and files from the MEMTEST86 iso.
2. Turn off overclocking and XMP. How? 
3. Ran test with both installed modules--failed.
4. Removed both modules. air sprayed modules and slots. reinsterted both modules. Failed.
5. Ran test with one module, i.e., "first module". passed.
6. Ran test with only one, second module. failed.
7. Ran first module in second slot. passed. 
8. Ran second module in first slot -- passed.  Very confusing result.
9. Ran test with both installed. Passed.
10. Rebooted with Unraid USB. Booted.

I am not sure what the problem was. I am not sure what the conclusion is.
