Another thing I would look at is the output of 'smartctl -HA /dev/sda', check the output for all disks and check for anything suspicious.

SMART is all OK on all 4 of my drives (which is reassuring!). I'll give memtest a good, long run after I upgrade and see what turns up then.

I have remembered something else, it does sound crazy but I have experienced it first hand a couple of times now. If you have a new (or known to be working properly) PSU you may want to try that too.

Don't ask me why but PSUs seem to go south after a few of years use and until they give the last fart all sorts of strange and untraceable things happen.

My desktop machine used to hang every once in a while when hibernating windows (and only when hibernating) and I thought it was just normal behavior, until the PSU was completely dead and made me think it had killed the rest of the pc.

Another machine (not mine) was hanging first only when creating a tar.gz of a few GB of small files and then at startup, I though it was a problem with the distro that was installed or that the HD or the filesystem were toast, turns out it was just a bad PSU, no one believed me until I changed it and the machine started working properly.

I have seen that before too on occasion -- but this is a brand new, good-quality PSU (can't remember the brand - Antec I think) that was only put in when I built the machine a couple of months ago.

I'll add that to the "Desperation List" of things to try if the problem persists after the mobo and RAM arrives tomorrow and I rebuild

Thx for all the suggestions!

Have you considered booting with one stick of ram, and having a look if that makes a difference?

Well new hardware has arrived, installed, memtest and the md5sum's all match now, so it looks like it certainly was something in the mobo/ram/cpu of the old stuff. I'll run it through an extra long hardware test next week at work.

Thanks again to everyone

Glad to hear things are looking better. If nothing else it was a good excuse to upgrade.

Yep - I'm impressed with the SSD

Good to hear that things are running smoothly again.

If you find the cause of the previous problem do let us know, at least I'm always curious to know these kind of things as they can be very helpful in times of need.

My invisible friend Richard, who happens to be a noted armchair psychologist, tells me you're likely suffering from GAS (gear acquisition syndrome) but you're still in denial ;P
