So i thought my built in media card reader was bad because my pc would not power on if it was plugged in. I sent my power supply and media card reader in for warranty and the company sent me brand new ones fresh in packaging. I plugged in the brand new power supply and media card reader (to the power not to the usb on the mb) and nothing power'd on. If i unplug the media card reader from the psu, bam it power's on like nothing. What the heck? Two months ago this exact same model media card reader and this exact same psu worked great. Now i can't plug it into power or nothing powers on. And its not a defective product because both of these have been replaced with the same results. any ideas?
