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 watts 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 on this FAQ 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
