I'm trying to install a Wireless adapter into my custom desktop. Whenever I insert the card into a PCI slot, the lights on the motherboard and graphics card turn off/computer won't power on. The second I take it out, lights come back on and computer boots normally. Any ideas?
 
Solution
maybe a bad wireless network card.

are you disconnecting the power-cord before plugging in the adapter?

What is the make and model of the motherboard?
