electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as those in major appliances, avionics, communications, or medical equipment also have self-test routines http://www.computerhope.com/beep.htm which are automatically invoked at power-on. The results of tests run by the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show https://en.wikipedia.org/wiki/Power-on_self-test error codes as a sequence of flashes or beeps. In addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

Maybe you get a bad system update from Microsoft or cosmic rays flip the wrong bit on your system. Whatever the cause, often your problem has nothing to do with hardware, but lies within the software powering it, instead. This recently happened to me when a USB 3.0 port on my system suddenly stopped working. I wasn't sure how it happened, and when I looked into the problem Windows displayed its infamous "error code 43." Luckily, this problem can often be fixed in just a few clicks. Try this out before freaking out if one of your PC components suddenly stops working. Device Manager This USB component is working, but if you've got a device problem this tab will tell you. On Windows 8.1, right-click the Start button and select Device Manager from the contextual menu. Windows 7 users can find out how to open Device Manger here. Let's continue using the borked USB port example. Fixing code 43 isn't just for USB devices, though—it's a quick tip you can use to help troubleshoot any PC component that ceases to work due to a software issue. Once the device manager is open look for the heading that says Universal Serial Bus controllers and click it to reveal a list of all the USB devices on your PC. In the list, you may see an item that has a yellow triangle with an exclamation mark in it and says "Unknown Device." Click on that and another window will open. Under the General tab you'll see a window that says Device status. For this tip to work, that window should say "Windows has stopped this device because it has reported problems. (Code 43)". Now it's time to get to work. Sometimes an uninstall can fix it all. Open the Driver tab and then click the Uninstall button. This will remove the USB controllers driver software (the low-level programming that makes the hardware work) from your system. Next, you have to put it back. Close the smaller window for your USB de
