Hello this issue is such a nightmare that I haven't been able to find my solution to this problem. I recently bought a new graphics card ( Sapphire Radeon HD 5450 ) to replace my old integrated graphics card on my computer ( HP Pavilion Model a6157c). I first thought the problem was my PSU so I bought a Cool Power 700W Performance series. Well to my luck the problem persists. Whenever I plug my VGA cable to my new graphics card my monitor stays on " Going to sleep " but when I plug it into the motherboard VGA spot it starts up but doesn't acknowledge that the video card is there. I am not super smart with computers so I am lost. Please help me with this issue.

can you change the one you bought,some suppliers will take it back for a small restocking fee and don't charge it if you buy another one
