There is a fuse, but you are about on schedule to need the power supply
recapped. Most likely output filter capacitors or kickstart capacitor,
but have the tech just replace all of the electrolytics on the supply
board with 105C types. It's not worth the time to diagnose it because
if you replace just the caps that are bad, more will go bad next week.

You may have other problems as well but replacing electrolytics is going
to have to be done in order to find them.

Doubtlessly. But presumably something else unwell that would cause the
fuse to pop. And/or a blown capacitor. Or a seized HDD, Or .... ?

Alesis HD24? Good. I don't know anything about it. Just checking to see
if this was your shorthand for the Mackie HDR2496 (which does have a fuse).

Popping sounds are usually capacitors or diodes, and occasionally
resistors. Open it up and see if you see anything burnt or split open.
Sniff around for smoke, or, if it powers up at all, look for smoke.

If there's a power line fuse that's consistently blowing, hook it up
with a 50 watt real light bulb in series with one of the AC power leads.
That will limit the current so the fuse probably won't blow, and then
you might be able to find what's loading it down by (after shutting the
power off) feeling around for what's hot but hasn't blown up yet.
