Anyone know any tricks

Time to sell your UPS and purchase one with a true sinewave output.

Yeah square wave and "modified sine wave" are not always that good.

I had an issue with my system powering down when the power went out, but it was the UPS drivers from windows. The APC ones fixed it up.

That said, non pure sine wave UPS's do make all my power supplies buzz on there power. so i use them just enough to shut down and am keeping an eye out for a good sine wave unit.
