I was installing a PCI-E port wifi adapter for my custom desktop PC. I did the usual thing when I install hardware, unplug all the cords and touch my tower to prevent static. I inserted it, closed it back up, but now it will not turn on. The little green light on the mobo is on showing it is receiving power but nothing. I've cycled power (pressed the power button while it was unplugged, holding it for 15 sec, etc) Used different outlets, but nothing. I don't have the liberty of seeing if it just a PSU issue by trying another since I only have one.
