So i finally installed my Zalman ZM80 heatsink on my radeon all in wonder 9700pro. Everything was going great, and the install looks fine. I put in the graphics card and I'm met with a long bios beep. Take out and reseat, the computer turns on eveyrythings great, and then it freezes up before windows gets a chance to load. I restart and im met w/ the same long beeps. I've tried reseating several times and the result has always been the same except for that one time. The zalman has not heated up at all. I have an abit ic7-g. Everything was working fine before I put the zm80 on.

Please help!

P.S.: I did plug in the power cable
