Hi Etsuko steal ayumi,

It has been correctly pointed by jack4rall that 3 beeps from `Dimension 4400' indicates that a failure occurred in the first 64 KB of memory. The suggested fix is to re-seat the memory modules.

If the issue still persists remove the Video card from the machine and check with the old Video Card if it works. This computer was shipped with 250 watt Power Supply. For this video card ATI recommends a 300 watt power supply or greater to ensure normal system operation where a number of other internal devices are installed. Click here to know more.

Hello,

Try this 1

If you notice that your CPU fan is running but there is no display in the screen,

then remove the RAM from the slot, clean it and place it back properly or try

another slot.

If you have no idea about RAM, then click on the below hyperlinks "Images".

RAM

Removing a RAM

Check your RAM also. Even bad RAM will result in display problem.

If you are having two RAMs then remove it, place only one RAM and check the

display. If you failed to get any display then change the slot. If you still failed to

get the display then try the above procedure with the other RAM.

Good Luck
Thank you very much you kind soul. It worked.
I'd tried it early but doesn't work. In past computer starts randomly when I was restart it in the button again and again. But now it's not working. Please help send me the help to ***@***
Just followed your instructions as my arcade game was doing the same thing. And it worked!! Awesome Thank you!
It's done that a few times in the past and luckily just starts working again randomly but that could be after months of not being able to use it. So thanks again for your help!
