Hi, I recently bought my first Mac and have been experiencing some problems. I just wondered if anybody could tell me what the best course of action is. 1. When turning off/restarting the laptop gets stuck on a Blue Screen with a wheel that goes around and around. I found it to be stuck on this for several hours till the battery ran out, so its not turning off. To turn it off, I am having to press and hold the power button. I dont want to keep doing that as obviously thats not the right way to go about turning it off on a daily basis. 2. The laptop keeps dropping the WiFi Connection, I have to re-enter the WEP Key each time it drops the connection too. 3. The laptop makes a CLUNK noise when I sometimes move it or pick it up. It comes from near the Optical Drive. Is this normal? Apart from that, Im loving my Mac but some of these problems are a bit worrying. Any help would be greatly appreciated. Thanks.
