I have a Dell Inspiron and have had it for a year. Over the past week, when I have been using the computer it stops responding and I am unable to do Ctrl Alt Del or do anything except a hard shut down. This has been happening at least 5 times a day. It is also not shutting down now.

Have you noticed any signs of overheating in the machine? When automatically the computer shuts down, does the Windows Logging Off message comes or it becomes non-functional suddenly?

Thanks for reaching out to us. That's a difficult question to answer considering the fact that it's life will depend on usage and handling. Please be informed all electronic devices are prone to mechanical and technical failures hence we have warrantied the system in order to support it.
