Something to consider if you have artifacts

Had a strange problem last night. All of a sudden, my perfect install of P3D started acting strange. I was taking off in bad weather and I was getting strange blocky spray effects. Then I'd get bright light reflections where there were no lights. Several other artifacts started showing up. I noticed that one of my two GTX780's was not being utilized as much as the other. I started getting flashing clouds and when there was a lightning flash, the screen would stay white for quite a while.

Anyhow, after much trial and error I traced down the culprit - I have (had) a Belkin UPS connected to my system. The battery was fine but for some reason the Belkin was NOT providing 120VAC to the system. The result was the PSU couldn't support the video cards and I had issues.

Ultimately I determined that the transformer had overheated causing the issue. Bye bye Belkin.

This is just a heads up - the UPS would not have been considered as a cause until I exhausted all other options. Might save someone some time.
