Unplug all power and remove and re-seat your vid card...

[jencurls]

You just saved my life!

Good News...

We love success stories here...and Welcome to CH !

So it worked for a couple days and now the fuzzy screen is back...any other suggestions you may have?  I tried reseating the video card again...works fine then it comes back.

[Spoiler]

Is anything pulling on the video cable?

[patio]

And/or is there another video slot available ? ?

[jencurls]

nothing is pulling on the cable and I dont have another slot...here's the big picture.  I have a room of 27 computers and they are all doing this...it's like a disease.  Once one computer gets the fuzzies then eventually they all get it.  Some computers are definitely worse then others.  Once I reseat the video it works for maybe a day or so and then its back better then ever!

If you have 27 computers all doing the same thing at the same time, it sure sounds like a power issue.  With that many computers, it would be worth the investment in a sophisticated power monitoring unit that monitors both voltage and hertz.

Electromagnetic interference
Don't have enough information to locate the source.
I can only assume this is in a computing center of some sort.  Most likely a power issue of some sort as "rthompson80819" has pointed out.

I suspect the vid card is dying a slow death...

Replace it..

I suspect the vid card is dying a slow death...

Replace it..

On 27 different computers all exhibiting the same symptoms?

[jencurls]

where would I even start if its a power source?  yes all 27 computers have the same issue, some are worse then others though...

You'll have to hire a consulting engineer who specializes in that sort of thing.  Google "data center power consulting".

Can you move one of the systems out of that room and put it in another room to see if it does the same thing?  Trying to see if it is the room the computers are in or the building.

Do you have battery backups for the systems and are they far enough away.  We had some that played *censored* with the systems if they were to close to the monitors or computers.
