ok first of all i have a dfi sli-d that I bought a month ago and I have started to have problems. First of all sometimes my sata hard drive does not show up that it is even attatched to my computer. Also, my device manger is showing that my ehternet controller and multimediia audio controller are not installed also. I just installed the driver that came with my sound card cd again and the multimedia controller worked but then my computere started to get bsod every time i booted up. Any help would help me out.
