Right I have a PC that randomly locks up and freezes. Ctrl - Alt - Del
does not work, only the reset button on the PC.

So it sounds to me either: (see later comments)

Overheating
Bad memory
Bad M2 SSD.
PSU going or gone bad.

I can go days without an issue and then on the odd day I will have a
single freeze then its OK for the rest of the day after a reset.

I have had one occasion where it froze 4 times in one evening.

Is there any logging software or event logs I can delve into to try and diagnose the trouble?

I had recently upgraded from 2 sticks of 16 GB ram (32GB) to 4 sticks of
32 GB ram (128 GB) and put in a 2nd M2 flash (same make and model as the
1st) and the 2nd one is used as a backup drive by Win 11 every Sunday to
back up the first M2 drive.

It was after this double upgrade than the freezing issues started to occur.

I have already run Win 11's own Memory tester and that found no issues.

The BIOS was recently updated so that I could upgrade from Win 10 to Win
11 as a newer BIOS introduced TPM support.

Hardware details are:

Asus Z490 Prime Mobo

Processor is Intel i5 10400 2.9 GHz CPU

The old memory is 2 sticks of Corsair Vengeance LPX CMK32GX4M2B32 and
the new memory is 4 sticks of Corsair Vengeance LPX CMK64GX4M2E32.

The original and the 2nd SSD is Samsung 970 EVO Plus NVME M.2 SSD

the graphics is a Radeon R9 200 series with 3GB ram. This is a bit long
in the tooth and I am minded to replace it once graphics cards prices fall.

regards

Stephen.

If you're asking for hunches ... mine would be PSU, maybe it was
marginal before and the new hardware is pushing it over the cliff?

Or for something more methodical, could you refit the original memory
and go back to single SSD?

Didn't think extra memory and an extra SSD would add much to the power
draw on the PSU to tip it over the edge?

Depends ho close to it's maximum power the system is, did it show any
signs of "stress" e.g coil-whine? (I realise you might need someone's
help with that) ...

First step : re-seat the memory.

Already done that and also used compressed air to blow any dust out of
the memory sockets....

The one thing you don't tell us about is the PSU - specifically the
make, model (and power rating) and age. It's very likely that the rated
power of the PSU is plenty for your system, but the actual stable power
you can get from it may be far less.

Two extra sticks of RAM and an SSD will add somewhere between about 15W
and 25W to the load om the PSU. Maybe a little more if the SSDs are big

1TB) which you don't say. That's not a lot, but could be significant, especially if it's getting a bit old.

I've had problems in the past where a PC became unstable or refused to
run after increasing the RAM -- increasing it to the max supported or
to use all slots where some were free before. This has been solved by
updating the BIOS ... but you've already done that. Don't dismiss the possibility that the new BIOS has introduced a bug. Is there a newer
one?

Is the RAM configuration you now have officially supported by your
motherboard? Are there any provisos? 128GB is quite a lot ... I wonder
whether Asus have tested with that much.

I'd try running with just two of the new RAM sticks, and if that seems
OK try running with just the other two. That will help rule out any
fault of the DIMMs themselves.
