This is a brand new card i just bought about 3 to 4 months ago. It worked just fine, then i upgrade to a new mobo, cpu and ram every since then the video card wouldn't display unless i unplugged it and plugged it back in then cut on the pc. I have to do this every time. I thought it wasn't enough power but i just bought a 700watt psu yesterday(Had a 500watt before) and its still doing the same thing. I have checked many threads but no solution for me.
