Shut down the PC, open the cover and look at the top of capacitors, does any look bulged ?
While open, power it on and run latency histogram for about 10 minutes, touch the CPU cooler, beware it can be very hot. Is it very hot?
While open, power off again, remove one of the memory modules, boot and test. Test both modules, granted there are two modules in it.
If there are two modules with no change in results and you do not end up with second degree burns on fingers/hand, then power supply or memory controller or failing hard drive, in that order.

No dodgy caps inside.
No overheating during latency histogram.
Ran automated latency test for a couple hours last night with no hiccups and really good latency.
Only one memory module and no spare laying around, so cant test that.
HD is an SSD that was newly installed when I bought it last year.
Power supply is the OEM HP, nothing fishy about it.

Time to break out the other SFF PC and see if the realtek NIC problems have been sorted since I tried it early this year.

One way to get a later kernel would be to upgrade to Debian 13 = Trixie = Testing
I think its on kernel 6.5. get the amd64 version, then try running andy's install script 
cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/
 
Rod - where would I find Andy's install script?  Didn't see it in the announcements or computers/installing sub-forums.

Its in 7,1.4 in the docs here
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel

@spumco, I can't remember. Do you have an R8168 et al NIC card?
add non-free to your sources.list and install dkms, linux-headers-$(uname -r) and then the r8168-dkms driver....
Failing that its time to build the 6.5 kernel from source.

Rod - yes, the 'backup' PC has an 8168.  The earlier failures were on an HP elitedesk 800 G2 I bought because the other one was unusable because of the realtek NIC.

I've got non-free in the sources, and dkms vomited while trying to install it.

DKMS needs linux-headers. Did you instll them? Using $(uname -r) makes sure you get the right one for your running kernel

Yep, shows up in synaptics.

not seeing a Real time version
Do you have a PREEMPT_RT kernel installed?
What does uname -v say?
