DELL 8400 MAKES A LOUD FAN NOISE AND WONT BOOT


There are 2 basic fans in Dell tower one for the power supply and the other for the Processor. If your computer is not booting then the Processor fan is most likely to be the culprit. What could be happening is that the Processor fan is no longer turning fast enough to cool the processor, so normal the processor when it over heats there is either protection to switch off the computer automatically or the computer won't boot. The best thing is to change the fan and make sure it is working properly but checking on the cables that they won't entangle on top of the fan to impede it's movement. You can easily damage your processor if the fan is not working properly.

I get 1 beeb followed by 3 beebs followed by 2 beebs then nothng happens dell diemension 8400


Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3) consists of one beep, a burst of three beeps. This beep code tells you that the computer encountered a memory problem
you need to reseat your memmry modules just remove them and place them back in the same or a diffrant slot this cold be loose connection by connecting them again you fix it

Chuck,
The 6 beeps are an error code. You should note a pattern such as 3 beeps, short pause, 1 beep, short pause, 2 beeps. Also, you may have a set of 4 error indicators on the back of the unit that will show a pattern of green and yellow lights. In any case, you will want to try to run the Dell diagnostics. Let us know the beep pattern and the light pattern and we should be able to give you some more specific information.
