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?
