Hi. I was a proud Macbook user until this happened to me! It was just 5 months back, I got my brand new Macbook pro - 13" with i5, 2.5GHz processor. A month back, I installed windows7 using bootcamp and it worked fine for just a day and my Macbook started to respond slow! So, I just thought, it could be because of windows7 and so, I uninstalled it. But unfortunately, the problem existed and I reinstalled Mac OSX not once but twice and still the problem exists! I was out of options and I took it to the nearby service station and after a week, they said that they could not find the problem. My laptop keeps on freezing every 20-30 seconds regardless of whatever applications I run! I have to write a report on my project and imagine if my laptop freezes every now and then. It would be really halpful if anyone comes up with a suggestion please!
