I've recently upgraded from a GeForce 3 to a Radeon 9800XT, and ever
since then I've been experiencing occasional lock-ups and/or BSODs, the
latter reporting a problem in dti2dvag and a "STOP: 0x000000EA" code.

The strange thing is the way it happens; the lock-ups always occur
within seconds or minutes of XP starting, usually while I'm at the
desktop. If it hasn't locked up after, say, 5 minutes, then it seems to
be as stable as a rock. On the other hand sometimes it will lock up
within seconds, so I reboot and it locks up again, etc etc, ad
frustration. These lock-ups have frequently occurred when the machine is
cold (and occasionally when it's not), so it doesn't appear to be heat
related.

In a fit of frustration I've re-formatted my hard drive and re-installed
Windows XP from scratch, tried updating my drivers, and even tried the
alternative "Omega" drivers, all to no effect.

If it's relevant here are my hardware/software specs:

Asus A7V8X motherboard
Athlon 2600+ CPU
512MB RAM

Windows XP Home (fully patched)
VIA Hyperion 4in1 drivers v4.51
Radeon Omega drivers 2.5.36a

Anyone have any clues as to where I should be looking for the cause of
the problem?
Faulty graphics card, power supply, drivers, BIOS settings ... ?

Any help greatfully received,

Ati and NVidia both seem to have very poor uninstall routines, Dave;
in both cases an uninstall still leaves a lot of files and registry
references on your system.

While these remnants may or may not cause problems with upgrades,
there's a much greater likelihood that they will cause problems with a
videocard brand change.

If you haven't taken steps to clean the remnants of your old NVidia
drivers from your system, it's quite likely that conflicts with these
are what's causing your problem. Apart from format C: there are three
less radical approaches you can take: you can manually edit your
registry and windows directory for remnants of the old drivers; you
can use a general cleaner like Driver Cleaner or jv16 Power Tools, or
you can use one of the specific NVidia driver cleaners; but you would
need to look in the NVidia forums for those, rather than here.

Point taken but, as I noted, I've reformatted and clean-installed
Windows + ATI drivers to no positive effect. (The reformat wasn't
just for this problem - it managed to sort out a general speed
problem with XP, so it was worth it).

Thanks for the info though.
