There are other testers out there, like the Retro Chip Tester Pro (which is good for testing RAM/ROM in particular), and in time I’ll probably acquire & build one of those too :-)
A couple of nights back my streaming PC got angry with me. The first night it bluescreened once, but it rebooted and the show went on. The second night, I think Obs crashed once and it bluescreened twice. Initial thoughts were maybe it was a driver or something that I’d installed recently, but that seems less likely now.
