Video Card Killing Monitors?

Hey there.

My son and I built a gaming machine which has been working pretty well.  He mostly plays Oblivion.  We installed an XFX GeForce video card.

The day before yesterday, his monitor died.  It was a really old Compaq 17" CRT monster, but there were no symptoms before it died.  It just died.

So, I had another CRT up in my office that I used as a workstation for repairing PC's (OS re-installs, virus and malware removal, etc.).

This worked for two days and then same thing - the monitor died.  I guess it could be coincidence considering they were both old monitors - but my concern is that maybe the video card might be frying them.  Is this possible?  If so, how can I tell for sure other than the "three's a charm" test?

TIA

I wouldn't blame the video card... but blame a faulty outlet, or unregulated weird power outlet... or not grounded...

I think the monitors are just old and were ready to die anyway.  The card, on the other hand, is more recent and cards are less likely to die.  You can test the output of the VGA port by measuring the voltage levels of the red, green, and blue pins - it should be between 0 and 0.7 volts.

Does the led indicating power to the monitor turn on??? if so, might be that you or your son put your pc to a resolution higher that what the monitor can handle!!! old monitors didn't have the resolution capability of modern monitors...

You can wreck monitors by over powering them.  If you have the refresh rate too high you can damage a monitor.

Whatboy may have a good point also,  If your son has turned the resolution up so high that the monitor can not display.

All good points.  I probably should have included the fact that I don't see post screens.  Would this rule out resolution settings?

I think I get lights on the both monitors - the Compaq for a split second and the other I think stays on but I need to check for sure.

Also, there is a DVI to VGA adapter in the mix.

Post shows that the monitor is probably not with us any more.  Can you test it on a different PC?

I remember one time with some freak weird monitors, don't remember the brand, that it had to be turn on first, then the PC, if not, you wouldn't get any video at all, and if the hardware screen saver kick in, forget it, had to reset the pc... weird...

Hi ttist25,
also remember that some video cards can output signals that some monitors can't handle.  Refresh rate being one of the settings.  Most of the newer monitors I've seen lately have protection circuits in them that shut them down if a harmful signal is present.  Be sure to check the maximum settings that your monitor can handle and run your video card at or below those settings.

Hope this helps,
Alan

If he doesn't even see the POST message, resolution and refresh rate does not play a role in this problem - this has been mentioned already.

A video card will not cause your monitor to burn in most cases.

Please check your the power that you connect to your monitor.

90% chance is the electric power that connect to your monitor is causing the problem, try connect monitor to other power source.

If either (or both) monitors have OSD controls, try bringing up OSD on monitor.  No OSD usually equates to a shot monitor.

Thanks everyone.  Still not sure what the cause was.  I'm going to get him a new monitor (probably get the two year replacement also) and we'll see what happens.

Thanks again!
