Thanks for the details.
If you have two memory modules installed, then test the system with a single module at a time. Here are the step:
1 Turn off the system (press and hold the power button for about 10 seconds and the system should turn off)
2 Disconnect battery and ac adapter
3 At the back of the system, take out the memory access cover
4 Take out all memory modules. Be very carefull. There are two ejector clips in both sides of the memory slot. Release the ejector clips by gently pulling them out of the sides of the module. Gently pulling both clips at the same time will release the memory module.
5 Then install a single module in one of the memory slots
6 Reconnect battery and ac adapter, turn it back on
7 If you do not get any display, then disconnect battery and ac adapter again
8 Take out the memory module from its slot and install it in another slot
9 Reconnect battery and ac adapter, turn it back on
Repeat the same steps with another moduleIf you only have a single memory module installed
, then you will need to get another memory modules and test
If it remain same after testing with two different memory modules, then next step will be to turn it off, take out battery and ac adapter
Take out all memory modules
Reconnect battery and ac adapter
Turn it back on and carefully listen for beep sound. If you still get the same beep sound then the problem can be with motherboard. In that case, you can try to disconnect all aditional hardware and then test the system (after installing a single memory module)
I could not locate a service manual for the system, but the following link will provide some pictures about disassembly procedurehttps://picasaweb.google.com/115937002727853862984/SamsungQ320DisassemblyGuide#
You can try to disconnect all additional hardware like hard drive, CD/DVD drive, WiFi card etc, keep one memory module installed and turn on the system. If it remain same, then it will indicate a motherboard problem.
