In these circumstances, my first step would be to verify the hardware.
The system's too young to expect failing caps within the motherboard,
power supply or other cards, so it's more likely to be bad RAM, or
possibly bad hard drive. It may also be "waiting" for some
peripheral, so I'd also test with all add-ons (printers, scanners,
etc. unplugged and off all networks (including WiFi).
Start by 24 hours of MemTest86, then I'd test HD using HD Tune from
www.hdtune.com (needs to be run as admin from Vista, can also run from
an XP/2003-based Bart CDR boot)
Second step would be to formally exclude malware. In XP, I'd run my
scanners and manual cleanup tools from a Bart CDR boot; in Vista, I'd
try the mOS built into the DVD's boot (repair, command prompt) except
I suspect lack of admin rights will cripple this environment.
Third step would be to reversably disable non-MS services, startup
entries, and other integrations, and then see if lockups only happen
when certain apps are in use.

>me it's nothing to do with heat.
Hmm, yes. No CPU heatsink (or a bad seal) will usually shut the PC
down before it's out of POST, whereas a fan snag may run for quite a
while; and finally, other devices (HD, mobo, SVGA) can overheat, too.
But I agree it sounds unlikely. If you said "I can work all day in
Word, but within a few minutes of playing 3D games, it crashes", I'd
suspect the graphics card, or (if graphics card recently added) a PSU
that is insufficient to power the card, or missing additional power
connections that some cards may need.

Standard tests when "freeze":
- move mouse; does pointer move on screen?
- press NumLock etc.; do keyboard LEDs respond?
- try responses to these keystrokes:
- Alt+Tab
- Alt+F4
- Ctl+Esc
- Ctl+Alt+Del
- press (do not hold) ATX off; do you get HD burble and shutdown?
- hold ATX off for 20 secs (will bad-exit Windows!!); does it off?
- press Reset button (will bad-exit Windows!!); does it reset?
IOW, what you're after is info on how deep the freeze, i.e. is it just
one foreground app that's busy, loss of screen display (i.e. lock keys
change keyboard LED status, ATX off press does normal shutdown), is
the processor still processing (no keyboard LED response to lock keys
is a strong indication it is not), etc.
>Questions:
>1. Is this a completely random thing that is linked with Vista being not
>ready for home use?
I doubt it, no. Not seen a pattern of such cases here, and my Vista
user base is almost all Vista Home Basic.
>2. Is there something else I can do to stop it happening?
As above. If you have your data backed up, can also return the PC to
reseller for warranty assessment, but brace yourself for it coming
back wiped and rebuilt. Them folks ain't always gentle.
>3. With my method of upgrading ( I followed the provided instructions to the
>letter) does this mean I no longer have Xp to fall back on?
Yep. An upgrade OS license replaces that which you upgraded from, so
from that perspective, you aren't entitled to keep both, even on the
same PC - so I'd be surprised if the process retained XP.
>4. Is it even worth me bothering with Vista? I have a computer to use for a
>variety of things, at the moment I am starting to feel like the upgrade was a
>complete waste of time, and money.
Difficult call. I'd say yes, especially given the spec, but the
benefits may only kick in in a year or two's time. On a new PC that's
expected to be used for 3+ years, that's valuable, but on a 2-year-old
XP PC that's expected to be replaced soon, I'd say not.
>5. Am I right in thinking that closing the system down in such a way could
>cause damage itself?
Yes. Vista will paper over this by automagically "fixing" everything
via AutChk, but you'd be bleeding from damage to file system as well
as the contents of files (which is disregarded by AutoChk).
It must be fixed, IMO.
