Maxdata tower computer : - when switched on bleeps 2/3 times and doesn't engage the mouse or the keyboard and the monitor shows " no video input ".Just no response and doesn't turn itself on...

BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device.
There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to the operating system.

I hope this helps.

My computer is beeping and the green light is staying on but the red light is not on and it just beeps i changed the battery and still beeps and no signal


If you are receiving continuous beeps, it means that computer is not recognising the RAM (memory). In this you have to open the Computer and follow the below steps:

1. Turn OFF the computer
2. Open the flap of the Tower (Remove the screws from the back of Tower)
3. Now, On the Motherboard you will be able to see the RAM see the picture nanjia.jpeg

4. There should be two pins to unlock and remove it
5. Once removed, clean the terminal and replug it.
6. Turn ON the computer, it should take care of the issue

Thanks and regards,

1 beep every 3 seconds

The system is having a problem accessing the system memory to refresh it, a problem either with the system memory or with the motherboard itself.

Computer problem

during these beeps there should be pause between them at some other words you may get 2 beeps/pause/1beep/pause/2 beeps noting the number of beeps and where the pauses are will help. From what you are describing and without more info it sounds as if you are describing beep codes, and they generally can give us a lot of information.

Tower pushing out air and beeping and can't turn on PC

the beeping is post codes. they are telling you something is wrong. the code is a code for what is wrong like 3 beeps 4 beeps 1 Beep then repeatsthat code is 341. first thing i would do is pull out you ram and reseat it. that is the most common problem.
