Looks like Memory Issue,
Memory modules are detected, but a memory power failure has occurred.
You can try as follows :
If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error. If only one memory module is installed, try moving it to a different DIMM connector and restart the computer.
If available, install verified working memory of the same type into your computer.
Step 1: A memory slot is a slot in your motherboard where you place your RAM (Random Access Memory) card. In layman's terms, the RAM is the "temporary memory" that the computer utilizes whenever it is turned on. If the computer cannot detect a RAM card installed in one of your memory slots, you have to troubleshoot the problem immediately. Ensure that the problem is with the RAM slot and not the memory card. Turn off the computer, unplug all devices connected into the ports of your computer and open the computer casing. Refer to the manual of the computer to know the specific steps to follow in opening the computer casing. Remove the memory card from the RAM slot. To do this, unlock the card using both hands. Pull the card away from the slot to remove. Inspect the RAM card for any apparent physical damages. Wipe the card with a clean cloth to remove dust. Also wipe the memory slot in your motherboard. Place the RAM card back into the memory slot. Press the card into the slot until it clicks into place. Close the computer casing, connect the cables back into their respective slots and turn on the computer. Turn on the computer and see if the memory is detected. If the computer does not boot up, the RAM card is not detected by the computer. Assuming that you have two memory cards installed in the computer and the computer boots up, check if the second memory card is detected by the computer. Click "Start," right-click "Computer" and then "Properties." Under "System," check the amount of "Installed Memory (RAM)." If the RAM is not detected, the RAM slot or the RAM card itself may be malfunctioning. Place the RAM card into another memory slot in your motherboard and see if the card is detected. If it is detected, the other memory slot is malfunctioning. Do not install any RAM card into it to avoid further damage. If it is not detected, the RAM card may be malfunctioning. Insert another RAM card into the slot. If the RAM card is detected, the slot is malfunctioning. http://www.youtube.com/watch?v=wGp5AiyJInI repair memory slot
One of the easiest methods of determining what memory your computer has and what upgrades you can install is to go to the Crucial Memory web site and use their Crucial System Scanner Tool, this will try to detect exactly what make and model your system is, and from this advise both what the currently installed memory is, and show compatible memory upgrades for your system.
Here is a list of beep codes, this may help determine the problem wit your system. 1. Keyboard 2. System Board1-4-X Error detected in first 64 KB of RAM.1. Memory Module 2. System Board2-1-1, 2-1-21.

Go down to where it says "Memory upgrade information"
be sure you are using the correct memory. The machine should also give you beep codes or flashing light codes if it doesn't get into the BIOS screen.
If you're using the proper memory, try to install it one stick at a time to see if it works at all
Try to seat one memory first than try the other one. One of them might be defected. Also check the memory slots, ensure they both work well. I had 2-512mb sometime system just detect 512 and other time 768. Since I replace both with new memory cards they work just fine.
The two beep code means no memory was detected. This might mean bad memory, memory that's loose in its socket, or a system board problem.
Make sure all the memory is firmly seated and latched into the sockets.
If you have only one RAM module installed, try substituting a known good part of the same type to see if the trouble clears up. If the memory still isn't detected you'll need a new motherboard.
If you have more than one RAM module, try them one at a time to see if you can isolate which is causing the trouble. (Testing the motherboard with known good memory is always a good thing to try. I have seen computers where all three RAM sticks were bad at one time, so I wrongly thought the motherboard was at fault. I always keep some good memory around for testing now.)
Okay, first things first. IF the memory you installed is 1024 and you are using the on board video and it is 512 MB, you will only have 512 MB usable memory. This is because the on board video uses the installed memory to function. What ever the video memory is, subtract that form the total memory. If this is not the case, try re-seating the memory. If the numbers still do not add up then if there are four memory slots, make sure the memory is installed in the same color slots. Most desktops with 4 memory slots have two slots one color and the other two another color. Make sure both memory sticks are installed in the same color.
You may need to install memory in matching pairs. If the new memory is a single 1Gb module and you didn't already have a similar one they may not work together. Try removing the original module(s) and see if it makes a difference.
