Hi guys.. I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that i've installed the night before. I know it might be the nvidia graphic card itself but I just dont have a clue right now. My mbp is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only. Please someone help me What should I do now? I had waited for around 3 months for my new i5 MBP since I sold my previous MBP. If i return this one, I dunno for how long I will have to wait again since I'm going to do my daily job on it. Please advice.. my mbp spec: macbook pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. *the attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera phone EDIT - I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before. Please help! I dont wanna toast my new MBP.
