Hello PK, actually I either get the black screen while in normal mode,
or it blinks if I get to the desktop.

I just now booted the PC back into safe mode (and it _does_ blink
every so often)

By "blink" you mean the screen goes black, then is restored?

Yes, goes black then returns. Hasn't done it for a bit however.

Is the display itself an LCD or a CRT model? If you're not sure what I
mean.. CRT monitors are deep, LCDs are thin.

LCD


after my failed attempt to reinstall the video, and it
shows the two adaptors back under Device Manager... but if I try to
boot into normal mode it goes black again.

Have you tried booting in VGA mode?

Yes, works until I change settings, then goes solid black. However:
just now after removing Display Adapters again it rebooted
successfully in normal mode, but at 800x600, and although I see the
two display adapters listed I got an error about:

"No ATI graphics driver is installed, or the ATI driver is not
functioning properly. "

I've uploaded a .jpg made from a screen shot to show you if it would
help at: http://home.att.net/jinnii/pcfixuns/no_ati.jpg


Is there another monitor available for you to swap in?

I just noticed a link on the desktop to "Unlock or buy NVIDIA
PureVideo Decoder" (which I did not download nor request... but I
noticed earlier this week under restore points something about an
nVidia installation.

There is a trial version of the nVidia DVD decoder available:
http://www.nvidia.com/object/dvd_decoder_1.02-196-trial.html

and that may be where it comes from.

In a previous post, you mention the ATI control center and a RADEON card.
The nVidia software apparently won't work with this.

So you might want to be sure that this is uninstalled properly.

By jove, that just may be it. I see under Add Remove Programs NVIDIA
PureVideo Decoder installed on Sunday (two days before the problems
started). I will uninstall it and the NVIDIA Media Center extensions
for display and see what happens.

Back in a flash. --Jeanne

I wonder if my son may have had something to do
with that?). --Jeanne

I suppose that's a possibility..

Hello, thanks for the quick reply. No, I did nothing that I know of
to cause the black screen on normal mode. My son loaded a few
programs that I believe utilized a different screen resolution, and I
noticed that there was some sort of nVidia update a few days before...

I'm afraid I posted a rather long winded message on this issue
yesterday but did not get a reply (on both this group and
windowsxp.video called: "Screen black, blinking; possible video
issue?"... perhaps I should not have done that?)

A question: I'm using my laptop now, and I will try to uninstall both
devices on the PC but can I do so in safe mode? And after, should I
go directly to safe mode or try normal?

You're getting just a black screen, no blinking? I normally see this
with
CRT monitors - does the monitor's power light turn away from green? If
you
watch and listen at startup, you might see the monitor power light go
from
(normally) amber to green, and hear the monitor click on - and then, a
quiet
click and the light goes back to amber. If that happens, the video
settings may be just out of range of the monitor. The monitor shuts off
to
protect itself. Alarming, yes, but actually easy to fix.

To fix it, press F8 when starting as if to get to Safe Mode. But instead,
choose VGA mode. This will start the system in normal mode except for
the
use of low-end display settings. You will be able from here to re-select
the display settings within range of what the monitor's capable of.

Two devices may show if the device has dual monitor capability.
Remove them both then reboot.
PS did you try to update the drivers, that caused this?

Good day,

I am unable to boot in normal mode, but am OK in safe mode (except for
the monitor's occasional blinking off and on). NAV scan under safe
mode is clean. (I can run safe mode with networking if necessary)

I think I need to uninstall and then reinstall my video drivers on my
new HP, running Windows XP Pro, dual core processor, 250 GB
hard drive, 1+ GB memory, RADEON X300 Series video card, and a
Princeton flat panel monitor.

One question: Under Device Manager it shows two instances of my
Display Adapter, identical but the 2nd with "Secondary" after. Do I
uninstall both or is one for safe mode? I was comfortable with older
computers, but feel hesitant with the newer ones.

Thanks in advance... Jeanne
