PowerUP doesn´t offer the same possibilities as WarpOS does. To get stable usage with WarpOS and Warp3D make sure your env settings are setup correcly, and that you have the recent libraries.
Sounds more to me that you should consider more or better cooling to your PPC CPU and graphics chip, as heat most of the times are the main problem.
-EDIT-
And no, you can´t use WarpUP programs with PowerUP, but you can the other way around.
