With the PC powered off, go back and check the battery installation and make sure you have the battery installed with the correct polarity.  The plus side of the battery is UP.   Also check all the internal connections. One may have been moved during the battery installation.  Also reseat (unplug then plug back in) the memory modules.

That beep code combination is not listed in the Dell manual. 

360 Beep Codes

thanks.

THe battery is installed correctly and i did go back to make sure every thing is connected fine. I check the 360 beep code again and find out it is the pattern like: 1-3-2, indicates "DIMMs not being properly identified or used". I checked the RAM and video card to make sure it is firmly plugged in. One other thing i found out now is the video card (not the orginal one) has a power connetion, so if the whole computer can not be powered up, maybe the video card does not has power supply too?

thanks

Reseat the memory modules with the PC powered off (unplug and then reinstall, one at a time).

The problem would not appear to be the video card or the PCIe power connection.  The PC is failing the "POST" (Power On Self Test) and the reason for the beeps.  There are also diagnostic lights that help isolate problems and they are listed in the manual.

thanks you very much, guys

THe problem resolved. IT is related to the RAM.

I place RAM one by one, one is making the same beep, no matter which socket i plugged in. (THis one the bad). THe other one started the computer, no matter which socket i put in.

Just that simple. I thought i will not make it work again. But  what caused that damage to the RAM? coincidence or something i did caused damage?

Memory is static sensitive and if the ram chips or the printed circuit side was accidentally touched and happened to cause a static "shock" to the module it can be damaged.  

Since you were inside the PC to replace the battery that could have happened.  When working inside a computer either wear a "grounding wrist strap" which keeps you grounded (preferred) or at least touch a metal part of the PC first to ground any static before touching anything inside.  The straps are inexpensive and anyone that works on PC's should have one.
