(AMI BIOS) A power-on self-test (POST) is a process performed by firmware msi beep codes or software routines immediately after a computer or other digital electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as http://www.computerhope.com/beep.htm those in major appliances, avionics, communications, or medical equipment also have self-test routines 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 https://en.wikipedia.org/wiki/Power-on_self-test detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show 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.

I get 2 beeps at POST which supposedly means parity circuit failure. I tried playing with the RAM (make sure it seated properly, tried different slots, tried different memory sticks) but that wasn't the problem. I thought it might be the motherboard so I replaced the MOBO and also purchased new RAM. Last night the problem returned.....the house post error 2 power flickered for a second, the computer went down and then tried to re-boot itself but couldn't. It just gave the two beeps. I completely shut it down for about five minutes then came back and tried booting it and it booted fine. This has happened in the past also where the house power flickers, computer won't re-boot, turn it off for 5-10 minutes and then it starts fine. The problem has also occurred on some cold boots in the morning but that is pretty rare. It's obviously not the MOBO or RAM. What else can cause the 2 beeps? Any thoughts? Thanks.

Beep code is defined by Bios.) Consult your mobo maker and search about its bios.
