Hello, <br />
We have a compaq presario x1000. Lately the screen has been going black, then a message: &quot;Nonsystem disk or disk error/ Strike any key...&quot; appears at the top left hand corner. After strking a key, nothing happens. We then have to do cntrol alt delete which reboots the computer. THis happens several times a day now and we can't think of any reason why it would be happening. <br />
<br />
We hope you can help. Thank you! <br />

Compaq presario x1000 shuts down randomly

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
