Hi guys..........I just finished installing a new CPU cooling fan. I had to remove the ASUS pt6 motherboard because I had to put the mounting screws through the back of the mobo. Now with all back together, she won't boot up. The power comes on, and all the fans and lights are on, but that's it. Is it a windows xp introduction to mobo ( again) that I'm dealing with or just what?.......I just finished the whole OS install two days ago, new mobo, cpu and had everthing running great. But then the colling fan came in the mail and I got OC hungry.................Appreciate your help.Kirk
