I'm really hoping someone can help me because I don't want my brand new 20" Intel iMac to be the worst purchase I ever made. I wanted to switch to Macs but I'm not being filled with confidence at the minute. I got my iMac last week and yesterday it completely crashed with a message saying I had to switch it off with the power button and back on again. "Fair enough", I thought, "there's bound to be teething problems with the new Macs". Today, however, it completely crashed with no message, everything just stopped working. So, I switched it off at the power and back on again and now I can't click on any of the names or buttons on the login screen! I've tried it with two mice to no avail. I've even left the machine switched off at the wall for half an hour and tried it again but I've had no joy. I know there's teething problems with the Intel Macs and everything but this is getting stupid. I've even been getting repetetive crashing of Safari (but only in my account, in my girlfriend's account it's fine). I'm wondering if we've got a faulty unit. Please help. I really don't want to restore the machine back to it's original state.
