Hi everyone,

I am in need of some assistance. I installed a new case fan today and may have knocked into my wireless card that was seated in a PCI-e slot.

I powered on the PC to test the fan and noticed there was no wireless connection. While the PC was powered on I inserted the wireless card again into the PCI-e slot. As soon as it was seated, the entire PC shut off. There isn't an LED light showing on the motherboard, all the cabling is secure in on the motherboard, I've changed power cords, but still am unable to turn the PC on or get any kind of lights to display.

Did I short the PSU? If so, is there any way to confirm this before I purchase a new PSU?
