I have ASUS P5G41C-M LX combo mother board with 1 x PCIe x16 slot, intel core2 duo e4400 2GHz,FSB 800MHz processor, 2GB DDR2 RAM & 450W psu. I installed Sapphire ATI HD 6670 1GB DDR5, installed it's driver. When my computer restarted the monitor screen became completely blue & it stayed. Why can't I run this GPU on my mother board, is there any hardware contradiction? Plz suggest me something so that I can replace it if needed in time.
