While installing my Xigmatek S1283 CPU Cooler on my CrossHair III MB w/Phenom 955........ I had trouble getting the 2nd retention bracket clip over the second tab/notch thingy and I forced it on with a tool that slid off onto a part of the Mobo that doesnt appear to have trace wires on this part but is a brown/orangish color I guess this is really hard to explain but I guess what I am wondering now.... Since I do not have my CD/DVD drive installed yet as I forgot to order it could I still just try to power on the PC without Keyboard/Monitor attached just to listen to for POST beeps to see if it is damaged or not?
