I like games of all types and sometimes try to make them. IT Professional who likes mechanical keyboards and weird hobby electronics too much. He/Him.
I’ve never understood the “these people hate Star Trek!” take I’ve seen around the new shows. It’s clear that nobody working on these sets out to intentionally make a bad show. Some of the Easter eggs and references are deep cuts, so it seemed obvious to me that the people working on these are big fans.
To give credit where it’s due, RotS and many of the Disney-era Star Wars products have gone a long way to fitting the glamorous, shiny prequel aesthetic into the gritty, used, “lived in” aesthetic of the OT. I’m not the biggest fan of The Last Jedi, but I actually think the implicication of the shiny galaxy just being a property of the rich inner rim planets was a great move in unifying everything.
I’m going to be honest, Klingons in the TNG era always felt too goofy to me. They weren’t a proud warrior culture so much as borderline clownish space vikings who spent more time getting drunk than actually conquering anything. A redesign and change in how their culture(s) present on screen was welcome for me, and I think Discovery did a great job. I even liked the way they recontextualized the Klingon language, to make it sound more alien and more threataning than the staccato, oft-mispronounced mess that we got in the TNG era.
That said, I also think there was a missed opportunity with them. For a long time, I’ve had a head canon of the different looks of Klingons throughout all of the eras could be chalked up to these all being distinct peoples from within the Klingon Empire. It stands to reason that over a long enough time scale, an empier spanning multiple stars would start to consider people not originally from their homeworld “Klingon,” even if they might be genetically different. I always thought it would be cool if the TOS smooth forehead Klingons were actually just one species that were culturally Klingon, where the Worf-type were another, and the General Chang type was yet another. It would provide a way to smooth over the aeshetic differences with an in-universe explanation that doesn’t require any retconning except for a handful of episodes from ENT that die-hards didn’t like anyway.
But oh, well. One can dream.
My bet is on either thermals or power supply.
Not likely to be RAM, since issues there are more likely to either prevent the machine starting in the first place, or lock up if it fails while the machine is in operation.
Not likely to be CMOS battery since that generally wouldn’t cause the machine to shut off, it just preserves firmware settings between power cycles.
In theory, there could be an intermitted short happening somewhere and the PSU’s OCP is kicking in, but I’ve never come across something like that. Similarly, there could be a problem with an internal power cable connection doing the same, but it sounds like you’ve already checked that.
I would test with a different PSU if you can. Thermals should be easy to check for too with the many pieces of available software to keep track of such things.
