Hi , i recently replaced my motherboard , power suplly , and case , and i am getting a blue screen error atikmdag.sys i searched a lot and in the forums they say it might be the new motherboard in conflict with the graphics card, and i found a solution for nothing it keeps getting me blue screen , i didnt change my hard drive , so its the same disk as the older motherboard was , maybe the solution is to format the pc and reinstall windows ? becouse i dont want to lost my things in the PC... Thanks
