After checking temperatures, hooking up a PSU is the next easiest thing you can do to isolate the issue. No need to fully install it - just remove the panel, disconnect your current PSU’s connectors, and then hook up the replacement with the PSU sitting out front.

Not sure how similar it might be in Poland, but in the US some corps have very flexible return policies so I would ‘borrow’ whatever’s convenient and then return it after ordering what I actually want.

Alternatively, your local repair shop could probably do this all within 15 minutes.

They’ve improved nothing at all in that time

A huge chunk of my work used to be fixing things after a client’s Windows OS went tits-up after an update for seemingly no reason.

These days, those cases are incredibly rare and when they happen there’s usually an underlying hardware condition.

Windows has been able to roll back botched updates for about 10 years now. I’d say that qualifies as an improvement.
