The heaksink/fan appears to be connected with a spring loaded mechanism that has two spring post on either side of the heatsink. I can lift it up a millimeter or so but that's it. How do I remove the heatsink? I'm wondering if my SB is the reason my computer will not turn back on. I turned off the computer to blow out the inside of it. While I had the case open I was jacking around with the sb heatsink because the fan started making noise. After hooking the computer back up it will not turn on. I've ruled out a bad power switch and the green light on the mb is on. Ohh, it's an ASUS A8N SLI mb. Thanks!
