BleepingComputer.com: PC won't start

I installed a new wifi card for my older computer. It worked fine until I restarted the computer. Now, it won't work. The computer just let's the fans spin but no lights on the front panel and no video on the monitor.
I didn't smell any smoke, so i didn't burn anything. I tried to make it work without the new card but nothing happens. The fans seem to be spinning inside, but the psu fan seems a little weak...

I dunno, help? :|

Will the PC work without the Wifi Card? If it doesn't, then most likely you burned your mobo or your connectors. See if it will work without the wi-fi card and reply back.
