Clicking on a video file makes monitor go black

I'm getting some really odd behaviour on my editing computer.
Whenever I right click on a video file (avi, mov, wmv, mpeg) on one of my
hard drives to play it, the monitor screen goes black for a second and then
comes back on. Sometimes, it doesn't go all black but it has a small
momentary partial black glitch, but more often it goes totally black for
about 1 second.
I have no unusual software on this machine. Just video and audio editing
related software. No internet or games or firewalls or virus checkers. It's
optimized for video editing.
The only software that has been installed in a while is the latest Avid
Xpress Pro 4.6 upgrade.
While trying to check on this problem, I noticed that device manager
reported a default monitor and when I tried to reinstall the inf files for
the monitor, windows failed to start after I restarted. I tried twice and
windows would go black after the xp logo screen after the bios screens. I
had to use last known good configuration to get back into windows.
I reinstalled the latest drivers for the video card and the monitor inf file
and it then worked ok. But all this happened after the original problems and
did not make any difference to the problem.
It's still going on. It happens all the time, whether I've been running
programs or right after a fresh start.
I have an MSI 128 mb Nvidia GeForce FX5700 ultra video card and an Iiyama
Vision Master Pro 400 17" monitor set at 1024x768 at 32 bit colour and 85
refresh rate and am not using normal default settings in the options of the
video card. Windows Xp SP1 is installed with a P4 3 ghz cpu and 2 gig ram.
There is Direct X 9c, Media Player 9, and quicktime 6.5 installed on the
system with the rest of the editing software.
Can anyone please offer some advice on what may be going on here?
Thanks a lot for any advice.

That's probably because it was running at too fast a refresh rate for your
monitor. You can push f8 at startup and start in vga mode to fix that.

All I can suggest is reinstalling directX

"I was also experiencing these annoying sync-problems. The cause for
this lies in nvcpl.dll - a nvidia dll, which scans for connected TVs.

The first time the dll is loaded, is at windows-bootup
(HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft->Windows->CurrentVersion->Run).
This causes the first flicker and unfortunately the auto-startup-entry
can't be deleted.

The flicker when right-clicking on video-files is caused by a shell-
extension, which the nvidia-driver installs for all types of video-
files. This shell-extension calls nvcpl.dll everytime you right click a
video file to scan for connected TVs. If a TV is present, the shell
extension shows up in the context-menu as "Play on My TV". I never
tested this, but I suppose when you click it, the video is directly
shown on your connected TV.

This could have been implemented a lot better, this f...ing sync-flicker
is driving you crazy when browsing a video archive.

After scanning the registry, I found the key responsible for the shell
extension. Just search for "PlayOnMyTV" in the registry and you will
find some entries under "shellex" (shell extension). These entries
contain an identifier, {FFB699E0-306A-11d3-8BD1-00104B6F7516} in my
case, I'm not sure if this identifier is static or created dynamically,
so in your registry, it might be another number. Now copy the identifier
and search for it in the registry; delete every occurence when it's
connected to video-file formats (.avi, .mpg, .mpeg and so on) and
afterwards the "PlayOnMyTV"-shellextensions."

could be a nVidia driver problem with nvcpl.dll

REPOST from someone not so long ago:
my monitor displays
goes black (as though the video signal has stopped) randomly for a few
seconds and then comes back. Occasionally it is long enough for the
monitor to go into standby mode so fairly certain the signal is
ceasing.

In fact, I've already disabled nvcpl.dll a long time ago, because it
was
causing unstability under Win98SE (ISTR) running Nero.
I took the opportunity to clean also other non desired programs.

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run-]

[...]
"OWCCardbusTray"="ocbtray.exe"
"WinFast Schedule"="E:\\My_Programs\\Multimedia\\WinFast
WFTVFM\\WFWIZ.exe"
"WinFoxV2"="E:\\WIN98\\SYSTEM\\WF2K.EXE"
"WinFast2KLoadDefault"="rundll32.exe
wf2kcpl.dll,DllLoadDefaultSettings"
"NvCplDaemon"="RUNDLL32.EXE E:\\WIN98\\SYSTEM\\\\NVCpl.dll,NvStartup"
"nwiz"="nwiz.exe /install"
"nForce Tray Options"="sstray.exe /r"


Then I looked for the value you said (PlayOnMyTV). Unfortunately it's
not in
my Registry.


I found two other occurrences of nvcpl.dll :
[HKEY_CLASSES_ROOT\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F7516}]
@="NVIDIA CPL EXTENSION"

[HKEY_CLASSES_ROOT\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F7516}\InProcServer
32]
@="E:\\WIN98\\SYSTEM\\nvcpl.dll"
"ThreadingModel"="Apartment"
and

[HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F
7516}]
@="NVIDIA CPL EXTENSION"

[HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{67E0E3C0-3068-11D3-8BD1-00104B6F

@="E:\\WIN98\\SYSTEM\\nvcpl.dll"

Thanks for the very informative reply.
I also have another nvidia card, a GeForce fx 5200 128 mb on my internet
computer which doesn't misbehave at all, yet the computer is a general
purpose family computer loaded to the gills with all sorts of crap, plus
broadband and firewalls and virus checkers and games. And it has all the
same software as the editing computer as well.
The cards are from different manufacturers, but the computers are very
similar in other respects such as motherboard, cpu, ram and monitor brand.
Why do you think that the barebones editing computer monitor would be
playing up when I right click on a video file while this other computer is
rock solid?
Could the problem perhaps be in any way connected to a fault in the monitor
itself or something else like a cable?
Thanks.
 
Mac,
I tried your advice and it worked!!
Thanks a lot for your help.
Let me report, though, that the search on my computers regedit failed to
turn up any Play on My TV instances, and there was nothing about shellex at
the location you mentioned.
But as it happens, my internet computer also has another nvidia card, a
5200, and a search on this computer's registry did turn up several instances
within the local machine/software/classes directories under various video
file extension names (avu, mpeg, wmv) although not others such as mov and
omf.
Using this, I was able to find the play on my tv entries on the video
computer and after I deleted them, the problem disappeared.
But the problem doesn't occur on my internet computer with its nvidia card,
so I've left that one alone. They both have the same driver although they
are from different manufacturers (the problem card was a 5700 ultra from
MSI, the other one I forget but its only a 5200, which is not classed as a
performance card by nvidia like the 5700 is. ha ha).
Now the only time that I get a screen blackout is when I'm in the display
properties window itself and I click on some tabs in the advanced area,
mostly monitor and adapter, but also just by going to advanced. I tried to
see if these had some similar settings in regedit but I don't know enough to
find them. But I use this so rarely that I'm not too concerned.
Nothing like this happens on my internet computer and its cheaper nvidia
card.
Thanks again for your help.

I don't know. Each time I have had the problem it just started happening.
It didn't seem to coincide with a new driver any other change, it just
seemed to start out of the blue.

monitor itself or something else like a cable?

That was my original thought, but changing monitors or cards doesn't solve
the problem.

Glad to hear it worked for you.
