Shoutout to the weirdest BIOS bug I've ever seen

Spent 4 hours on a machine that wouldn't boot, only to find the issue was a USB mouse receiver plugged into a 3.0 port. Has anyone else run into something that simple causing that much chaos?

My buddy's brand new PC had the same total boot lockout from a cheap USB desk lamp. Ross.kevin is right that it feels like a fluke, but it's crazy how a tiny bit of bad power can just brick the whole post process until you find the right cable to pull.

Honestly, that sounds more like a fluke than a real bug. Those kinds of gremlins usually point to a deeper hardware problem, maybe a failing port or a short on the board. It's wild it stopped the whole boot process, but fixing the mouse probably just bypassed the real fault for now. Seen similar stuff where a bad keyboard made a PC act possessed until you unplugged it. Wouldn't call it a BIOS issue so much as a weird symptom.

Yeah, that's exactly it. It's like the system gets confused by a bad signal and just gives up. I've had a USB hub do the same thing, where the PC wouldn't even post until I yanked it out.
