Monitor image "popping"

Is there any obvious source which would cause the image on my Sony monitor to "pop" (in & out).  I believe this started when I tried to update my N-vidia graphics card driver.  The new updated drivers caused all kinds of problems with my computer so I reinstalled the previous drivers (as well as monitor driver) & it was then that I started to observe the "popping".

Thanks for any suggestions.

Try the monitor on anouther computer to see if it is not a problem with the monitor.

The problem may lie with the updated driver. As you have stated, you reverted back to the old driver but some of the updated driver files may be lingering.

I am fairly sure NVIDIA drivers have an uninstall feature within control panel. Have a look and if it's there, uninstall, then remove the video card from system settings and reboot.

Windows should then recognise the card and install the old driver in it's previous state. Hopefully this will fix your problem.

Sounds like the installation of the graphics drivers set all the settings back to their defaults. Check your refresh rate specifically as the default is 60, rather low. It is not unuasual to have to reset the resolution and color depth as well. T

Do you get it on a basic resolution, say 800 x 600 at 256 colours, at a 60hz refresh rate?  If you do, the monitor sounds on it's way out.  If you don't, check that the new settings aren't pushing the monitor beyond it's limit, thus overloading the electronics.  Overly high settings can damage monitors, so be careful...!

Dan,

If he can get in with low resolution, it does not point to a monitor problem, it can merely mean that the resolution he has chosen is too high and the 'modern' electronics of the monitor will not display it, thus saving the probability of damaging the monitor.

The "popping" is not a problem, as long as the image settles down and is stable.  DanCh99 is right - it could be a sign of a failing monitor, and if you drive a CRT monitor beyond its refresh rate design, you can damage it.  How old is the monitor, and how long do you keep it on each day?

Errrr, I think I added my last comment by accident, for some strange reason I thought I was replying to the "Black Monitor" problem. Silly Me!

Thanks for all your feedback.  
(1) I already have removed & reinstalled the drivers.
(2)  The monitor is set to 1024 x 768, 16 bit color, & optimal refresh rate.  This has always been the settings.
(3)  the "popping" occurs MAINLY after rebooting.  It then settles down to an occasional "pop".  

It seems unlikely that the monitor is on its way out since the symptom of "popping" started at the specific time after trying to upgrade the drivers.  However, the monitor (Sony HMD-200A) is 5 years old & is left on 24/7.

Ah, I think you are seeing the beginning of old age creeping in - 5yrs of continuous service is a reasonable time for a CRT monitor to last, and these pops are the beginning of a component beginning to fail.  When you upgraded the drivers, it could have changed the refresh rate and stressed a component.

You may have removed the driver and reinstalled, but as I said earlier, lingering files can create havoc.

Did you try removing the video card from system settings and rebooting, after removing the nvidia software?

TheGafferCommented:
Also, what problems did the nvidia driver cause on your PC?

jarichCommented:
Maybe it is just a coincidence that it just started popping, but 5 years full time running is a long time for a monitor. Maybe restarting the monitor put a stress on it (cold boot).

I have done the following & the popping has gone away:

1.  Cleaned out the Registry using "Registry First Aid".
2.  Performed a Scan Disk followed by a Defrag.

Voilà, no more problems.  I will put in a request to delete this question since no one suggested the solution which I found on my own.  By the way, for the gaffer's knowledge, I had removed the video card from System Settings prior to rebooting.  That did not solve the problem.

It sounds like you did have some old drivers mess in your registry. The old drivers must be completely uninstalled before the new drivers can work. I think TheGraffer came as close as anybody to the real answer.

Yes, but you did not uninstall the nvidia drivers from add/remove programs, it would seem, hence the need for a registry clean.

Anyhow, glad to see it is now working

FYI:  I did uninstall the nvidia drivers from add/remove programs!
