When I had the drivers intalled and stuff I went to play BF3. Then noise started coming from my power supply and my screen started flickering horizontally. Game performance was normal, it ran BF3 with all on ultra and with 4xMSAA @ 40-60FPS or so. Turns out it's with all 3d applications. turning vsync off increases the flickering and the noise. Some research and i found out that somebody had also bought the same card from the same shop. Having the same problem he had sent it to warranty and he got a replacement, but the problem persisted. What should I do?
