You mentioned a buzzing in another reply. That sounds like a grounding issue to me. Any chance you blew something under the board that is causing a short? At this point it would be wise to do a full tear down.
I’m almost at my train stop, so one final question before disappearing for the day: when resocketing the CPU did you put it in correctly and was there damage when you removed it initially?
I block the users as well since they’re likely to post in yet another new community not in my block list.
If voyager had regex filters for every block category it would make the Lemmy experience even better.
