The Nvidia driver distributed with Vista RTM (32-bit) worked perfectly. I
think it was 96.86. Yesterday I downloaded the newest version (97.46, WDDM)
from Windows Update only to find nothing but flickering diagonal purple
lines on the screen this morning. CTRL-ALT-DEL changed the lines to green,
but I couldn't get into the task manager or do anything else and was forced
to restart the machine. Restart was normal escept for the "safe mode"
prompt.

My graphics card is an XFX 7900GT; Motherboard: A8N32SLI. CPU: AMD 4800+.

Any suggestions welcome -- I'm hoping not to have to revert as the new
driver gives slightly higher benchmark scores.

further to my last: the problem occurs after the monitor has been shut down
after the period of inactivity established in the power settings. Thus it
may have something to do with the way in which the new video driver handles
power down for the omnitor. Is there any place at which this can be modified
or adjusted?

Thanks again to all.

Control Panel | Power Options | change the plan settings for whichever plan
you're using...

Thank you, Lang. I tried that but none of the settings seem to affect the
problem with the newer driver. I'm pretty sure that the later driver alters
the ACPI setup somehow. I found a errors like this in the system log which
seem to correspond to the crashes.

IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 23,
function 0. Please contact your system vendor for technical assistance.
[this is repeated four more times, each time for a different PCI slot]

I've also tried all three settings of the hibernate/sleep states in BIOS:
S1, S3, AUTO. The system file checker reveals no problems. No joy. I've
pretty much used up my troubleshooting expertise on this, and I hope there
are more suggestions out there.

Of course it may be that the problem is a driver bug & if so I can only hope
that Nvidia or Microsoft pick up on it.

Thanks again.

Yeah, sounds like a driver problem. My only suggestion at this point would
be to roll back to the previous driver... in any case, good luck.

I am so gald I found your post... I have been going nuts over this. You have
almost the same system I have and I am getting the same problem.

XFX 7900GT; Motherboard: A8N32SLI. CPU: AMD 4800+.

I have updated with the latest drivers and am still having this issue, did
you find any resolution?

The 100.59 beta driver offers a partial solution -- but in large it's not
fully fixed yet.
