So I might have accidentally pull some components out while the PSU was still plugged in.
I dropped some screws on the mobo a couple of times.
However, I can still boot up with no problems.
Well, you answered your own question when you successfully booted.
Do you know his motherboard model?I've watched one member here on AT pull video cards from plugged in motherboards repeatedly, and he's yet to have one failure. Might say he's just lucky, but it works for him and his stable of >100 gpus he has on hand....that all work.
