I got a PCI wifi card for my desktop the other day. After putting it into my mobo, everything boots normally. However, after installing the drivers for the card, my mobo wont POST unless I physically remove the wifi card from the computer. I did this, uninstalled the drivers, and put the wifi card back into the mobo, and my computer boots normally, allowing me to conclude the drivers are causing my mobo to not POST.
My Mobo: ASRock x58 extreme OS: Windows 7 64 bit Wireless card: EDIMAX EW-7128G IEEE 802.11b/g PCI Wireless Card
I used the newest drivers from the edimax website, not the old ones that came with the card.
I have no idea what to do now, so I figured I'd ask and see if anyone has any ideas for me. I read all the user reviews on newegg and none of them seem to have had the problem that I've been having.

Quick update, it seems now just having the wifi card in the mobo, regardless of having drivers installed or not, is not allowing the mobo to POST.
Have you tried using it in a different slot? I've had similar issues a long time ago with sound cards.
