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.

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.

Don Lapre posted: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
