Hardware issue or error

Any failing hardware component in your computer could cause your computer to unexpectedly turn off without warning. If you have recently attempted to add a new hardware device, remove that device to make sure it is not causing your issues.

Before attempting to remove any hardware, make sure you are not encountering this issue because of hardware conflicts by viewing Device Manager for errors. Additional information about Device Manager can be found on our Device Manager page.

If you have not recently installed any new hardware into the computer, the next best solution to determining if this is a hardware issue would be remove any hardware on the computer that is not needed. For example, remove your modem, network card, sound card, and any other expansion cards that are not needed for the computer to operate. Run the computer without these cards to see if they are the cause of your issue.
