@fry_p It could be a monitor, keyboard, mouse, patch cable, video cable, or power cable causing the issue too.
We had a computer “Spot” once that was just voodoo’d. It blue screen’d, I said OK. Image it. Fixed. A few weeks later, blue screen. I said, OK it’s a hardware issue. PC Replaced, boom fixed. A few weeks later, another blue screen. I said, OK, this is highly unusual, but I’ll image it. Fixed. And again, another blue screen.
After that last one, I went in with a replacement monitor, replacement VGA cables, replacement power cables for everything, replacement keyboard, mouse, surge protector, and replacement patch cable. The whole 9-yards. Everything but the physical desk and chair was replaced. And that fixed it. All the old crap I pulled from there was marked “bad” and surplussed, I didn’t even bother testing those items as they were old and low-cost.
