The pattern of beeps whether its the beep codes dell number of beeps or the length of those beeps will give you an indication of the actual beep codes list problem. Its a distress signal from the computer in a morse code like pattern. Unless you have a diagnostic card to tell you more about

Everything is ok, that is if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMM's and reboot. If it does the same thing, one of the memory chips on the motherboard are bad, and you most likely need to get another motherboard since these chips are soldered on. 2 Short
by introducing more precise citations. (October 2010) (Learn how and when to remove this template message) The first stage of a typical POST operation. (AMI BIOS) The https://en.wikipedia.org/wiki/Power-on_self-test second stage of a POST. Sometimes, it is shown 'Boot from CD'. (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after a http://www.techadvice.com/tech/P/POSTcode.htm computer or other digital 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 beep codes 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 detect that the system's usual human-readable display is non-functional, an indicator post error code 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.
