Don't worry Arthur, my computer keeps on shutting down..just imagine, i was upgrading my cellphone's firmware the other day, i opted to connect it to my pc to do the updates online since the updater in my phone doesn't seem to work at that time..then in the middle of the installation, my pc shut down and i can't switch on again my phone!so in short, i sent it to the service center again and paid P560 for another software update!
