I've been having some problems recently, but until tonight, I wasn't too worried. I recently bought a Wireless Mighty Mouse. However, recently it has been acting up. It will suddenly lose all its abilities, apart from cursor movement (I can't click, scroll etc.) I could fix the problem by playing around with the bluetooth mouse settings. But, today, this happened again. I could not resolve the problem by playing around with settings, so I disconnected the mouse, to try and reconnect. Then, to my surprise, my iMac claimed there was no bluetooth available, and said that I had to connect a bluetooth module. I am using an iMac G5, so bluetooth should be bundled with the mac... The wireless keyboard, however, was still connected, but had a different name ( some collection of letters and numbers. ) I was trying to get stuff to work, when the fans started spinning wildly. I couldn't even hear other people speak properly. I turned it off, and now, it is fine. The fan problem has happened before. This is when others put a cloth over the mac so it is not in view from outside. I imagine they sometimes leave it on, for when I get back, and lift the cover, the fans are on wildly, dust is flying everywhere, and the mac is very hot. I am worried this continual covering of the mac could have damaged something... I am worried these problems are linked, as they happened one after the other... What are your thoughts? EDIT: Sorry I put this in the wrong forum. Could a mod move it to basics and help?
