Surprise, surprise the graphics card on my mid-2010 MBP failed or was corrupted. Seems there is a definite trend with these MB's and their graphics cards failing. Anywho, Found out it was out-of-warranty and took it to the geniuses who quoted me at 310$ to have the motherboard et cetera repaired. I opted out and read that I could simply use GfxCardStatus, v2.3 on Integrated graphics only. Since using it, I haven't had any intermittent shutdowns or the others issues associated with such. However, this seems to good to by true. What is the caveat to using this software? will it eventually ruin my computer or cause any adverse side-effects?
