On my desktop. What could cause this, and no, the power switch is not stuck. It just switches off and on all the time.

Something is failing on either the PSU or the MB.
Switch-mode supplies generally have a crowbar circuit which prevents damage if they detect overload currents been drawn off their rails, resulting in what you are seeing. This can be either some components on the board loosing the magic smoke, of perhaps capacitors failing, again either on MB or the PSU itself.
Try swapping out the PSU, to determine where the fault lies.
