RE: Is there a way to check if the cap is good with a DMM?

If I suspect any of the filter caps, in the main PSU, I just replace them. Usually, the first pi-stage's caps get the most abuse and fail the earliest.

Caps in this stage can be far off the rated nominal value and not cause catastrophic damage to the rectifier or fuses to blow. 50% or more from nominal. Now, they prolly won't filter as well as a good tolerance cap. But, they really need to be near short to ground or no conduction at all, to cause major damage to other parts. At least, in my experience.
