PC shutdown issues / gasping for air on shutdown

Hi all!

I joined so I could ask this question, which I could not find on the forums. That being said I am unsure how I would characterize the problem, so I may just have been looking in the wrong places.

I recently opened up my computer to install a wifi card, and ever since my PC refuses to fully shut down. It will go through the motions of shutting down windows, shutting off the monitor, and finally turning off the fans. It will wait for approximately two seconds before powering up the fans for a couple of seconds (power light on, monitor off), and then powering them down. It will painfully repeat this cycle to no end. The front power button does nothing during this time, and the only way to get it to stop is the power supply's switch in the back.

I thought it could be an issue with the network card, so I replaced it with similar results (shut down with no issue once, then refused to shutdown ever since). I believe this happens as well if the computer goes into hibernation, so I have disabled this setting.

Have you run into anything similar before? What would you recommend looking at?

Only thing I can think of would be some sort of WakeOnLAN setting. Any kind of network activity and your system resumes power. If you remove the WiFi card, the system shuts down normally, correct?

P.S. Also, might I direct you to our sister-site forums: Tom's Hardware Forums - Systems. We're more hardware related over there, but we'll see if we can get you sorted out here first.
