i have this card reader that i have installed on the fron of my pc and for some reason when i hook it up to the mobo my pc wont make it past the bios check. when i unplug it the pc boots perfetly fine. it is an older reader and thinking maybe that is the issue i dont have any sort of model numbers or anything to it i ripped it from my friends wifesd pc

Might be broken, Pick up a new one for like $5

it was working when i removed it i tested it in another pc as well and works on it
