I LOVE THE WHITE STRIPES!

At least I assume it's static.

I have a glass desk with a monitor wall mounted, computer on floor in a nice case. I have carpet in my office. About %90 of the time I walk into my office, sit down in my used old rear end Herman Miller chair and the goddamn screen will lose sync and maybe come back with a picture 10-20 seconds later. Sometimes the keyboard/mouse will actually stop working and all my USB ports stop responding when this happens. I have to remote into the computer and do a shutdown.. which lets me know the computer is still running.

Now the kicker, this has persisted over 3 different motherboards and 2 different video cards and 3 power supplies. I just decided to bypass my Cyberpower 1500va UPS to see if that helped and I can't really tell yet. The UPS has been a common thing between systems.

What in the goddamn hell! It's driving me nuts.

Is the red Wiring Fault LED on your UPS lit up, indicating that your power is not grounded?

hello :)

Save for a metal rod poking out of you case into the carpet and directly touching your cpu , i think you've done the only solid thing you could do. Oh and change the power plug that goes into the computer

As stupid as this sounds, I am considering grounding my case directly to my house.

Oh, and after disconnecting my Cyberpower 1500va UPS (non pure sinewave) the problem has stopped. I suppose now I get to find a UPS that doesn't do this.

If you're having problems you're either holding the phone wrong or you have tiny girl hands.

If your outlet is grounded then the case is grounded directly to your house.

I know, after trying so many different computer parts I was kind of desperate for a fix. In any case the UPS is somehow making it happen.

I figure I should get a line-interactive UPS with pure sine wave output like this: https://www.amazon.com/CyberPower-C...s+sine+wave+apc

Cybernetic Crumb

Hey I had this same thing where I would shift my weight in a certain way and my graphics card would crash. It turned out that there was a short in the electrical wiring beneath the floorboards. When I would stand up it would flex just enough to cause an interruption in power delivery and my monitors would switch off.

edit: I weigh 150lbs NOT FAT
