If that doesn't do it you need to isolate the problem by removing parts of your system one by one.

Since this seems to point to the interface, unplug it and use your PC's internal sound chip for recording by plugging into the Line In on mobo and use headphones on the PC. That should tell you if it's the interface or not.

If not, remove and replace every single cable one by one.

If not test the speakers. Unplug them and use headphones out of the Integra.

If the noise is still there then remove the Integra, use the headphones on the interface which tests the Integra.

Then uplug everything from your UPS and plug everything direct into your wall outlets which tests the UPS.

Somewhere during this isolation testing that noise will disappear. If all that fails then take the PC to another room and test it by itself using headphones into the mobo since you've already tested everything in your studio room. That means it's something in the PC itself probably the mobo or power supply.
