New imac freezing. Help!

My usb keyboard and wireless mouse freeze on new 27" imac randomly and unexpectedly. It began last night, and froze 3 or 4 times. Only way out is to hold the power button till it switches off. Imac is less than 3 weeks old, and I've only used it for a few days. Has anyone else come up against this problem, and do you have a solution? Thanks


You have 90 days of free AppleCare telephone support, give them a call immediately. They will assistĀ  you on how to handle this, on a new machine it should work flawlessly. You can locate the correct number in your area by clicking
BTW, have you installed any antivirus apps or any apps to "clean" or maintainĀ  your computer. If so I suspect those are the source of the problem and should be immediately uninstalled because they are not only completely unnecessary but tend to waste valuable system resources and tend to create more issues than they solve. OS X is very stable if left alone, it does not require 3rd party tools to maintain it like MS Windows. The very best thing you can do for your computer is to keep it up-to-date by installing the recommended updates found in System Update.
