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 667MHz RAM & 450W psu. I installed Sapphire ATI HD 6670 1GB DDR5, installed it's driver. When my computer restarted at first there were green vertical lines on the BIOS menu then the monitor screen became completely black & sometimes blue, & it stayed, but the monitor is on. Why can't I run my pc with this graphics card, is there any hardware contradiction? Plz suggest me whether to replace it or some modification can fix it?
