However it has been flakey: and the once-a-month issue with the
grapics card has been the least of my worries. Thunderbird
regularly freezes or crashes and has to be re-started (in fact this
is the second time I've written this because it just did it
again). Sometimes the entire desktop locks up such that the only
way to get out of the lockup is to turn off the power and reboot.
Firefox crashes all the time. Updates sometimes fail - sometime
leaving the desktop frozen as mentioned earlier.
I would run memtest just to make sure it isn't bad hardware - you never
know.

Thanks Hans. I will be doing that, when I get the time. I'll be
very upset if I find anything wrong. The machines on 6 months old.
OK. I've run memtest as one or two of you suggested. Could I now
prevail on you to interpret the results for me, please?
I left memtest running all day while I was out. The following is a
transcript of the screen as it appeared on my return (after nearly 12
hours). Apologies if it doesn't format correctly for you:

The bottom table was coloured a frightening shade of red. Do I have a
problem?
Yes, you're getting memory errors. If you've got more than one memory
module, you could try changing slots, to see if the problem follows the
module. If so, you've got a bad memory module. If the failures stay in
the same addreses, you've got a motherboard problem. Eitherway, it's
hardware. I believe you said it was a fairly new system. If so, you
should be contacting the vendor for warranty repair.
