Debian I had destroyed grub

Google lists multiple websites that discuss kernel panic diagnosis. Perhaps you can apply what you find there to solving your issue.

I have several PCs that have CPUs that are siblings to your LGA775 Wolfdale E5200, e.g. E7500, E7600 & E8400. Each of them works without panics with either Bullseye amd64 and/or Bookworm amd64.

Good luck finding your kernel panic solution!

I concur with mrmazda that there is a memory problem, from your panic screen shot:

EIP: acpi_ex_system_memory_space_handler..... code: 89 03 31 ........

I'd recommend that the OP seriously consider investing in a Hard Disk Drive(HDD/Spinner) that is targeted at the Small/Home office market sector in addition I'd also strongly recommend that the OP consider investing in a HDD that has A High Mean Time Between Failure(HMTBF) which means that it is less likely to fail on you when you most need it to.

The type of hard disk drive type that I mention in my recommendation above may run you a couple more USD per gigabyte but it will most likely out last your use of the machine.
