My mac starts making a loud noise kind of like it is working VERY hard every few minutes, even when it is doing nothing. It started about a week ago. Any idea what it could be, what I should do? Specs are in my sig. nRunning 10.5.1. The noise lasts anywhere from a minute to several minutes.
Also, I have NEVER been able to use sleep mode since I bought it without something weird happening. Either it just won't turn back on, or I will get a screen telling me that I need to restart my computer, like when you get a kernel panic. It is not even a year old btw.
