|You can't be sure if it shut off due to a hardware problem or the update. Since it's not even starting to boot into windows maybe it's hardware. Try to access bios setup when you first power it up. Here's a download for the manual if you're not sure which key to use:|
If you can open bios setup see if it's recognizing the hard drive.
Also try to access the windows boot menu using the F8 key. If it gets that far then at least you know the hard drive is being seen. If you get the menu try booting to safe mode.
