Why does only 1 memory slot works?

What is the pattern of the long beeps? one long beep or two long beeps, three long beeps?

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

remove the computer covers remove the memory from slot and clean the memory with clean soft clothalso remove the processor fan from the socket clean the surcace of the heatsink and the processor and apply thin layer of heatsink solventand fix the processor fan firmly on the processor socket

Once you installed the memory, did you enter into the System BIOS Setup screen? Do this and verify that the system recognizes the newly installed 2GB RAM. This should let the system access the new memory once you boot.

Hello.

At this point, from what you described, the memory stick or the slot could be the problem.

First check the 2 memory sticks to be certain that they are compatible with each other - the type and speed. That could be your problem.

If OK, remove both memory sticks and try the second stick of memory in the first slot. If it works, the 2nd memory slot is problematic.

If it doesn't work, your 2nd stick of memory is bad and needs to be replaced.

If the memory slot is bad, there really is not much you can do except replace your motherboard.

Hope this helps.

Seems the memory is not comatable with the motherboard. Replace the old memory and visit http://www.crucial.com, they have a scanner tool which will confirm what mem can be installed.

You have 2 sticks of RAM correct? One that came with the system and one that you bought. You also have to slots but it appears one may not be working, however, nothing is impossible but that is very rare it is normally the RAM itself and not the slot. Take both pieces out, put the new ram in the first slot and boot up. If the system will not boot up then it is the RAM because you already know that that slot is good. However, you cannot do the same thing with the second slot, because your motherboard looks for RAM in the first slot and if there is none then it stops boot. Conclusion: Put new RAM in first, slot if it works then second slot is bad, if it does not work, then RAM is bad...

Hope this helps. Please vote accordingly and if you have any more questions I will be glad to research and answer them for you...FixYa

The problem must be the amount of total memory. Maybe the board supports only 1 gig. Chek the manual.

you got the DDR 2 RAM right? and wont boot you say means you don have even the power on in the CPU or no display?

almost anything is possible, but in general a 430 watt P/S should be able to run 2 gigs of ram, however that doesn't mean that the ram you purchased is the correct ram for the motherboard or that you have so many other added perpherials i.e. dual or tripe CD drives, hard drives, USB perpherials that the load is simply to great for your P/S. A rule of thumb is find out what your system ' will ' run with and then work from there. For example if a person was serous about this problem he might disconnect all power connectors to all other equipment other then his hard drive, monitor/video card, and his motherboard just to see if the system could then boot normally. If it did, chances are the memory is okay for the motherboard in normal circumstances. However if the system did not boot normally, it might be an incompatibility with the 2 gigs of memory on that particular motherboard. Memory is not a generic add-on. A person needs to make sure the memory is correct for a motherboard before installing. Also you indicate the present P/S is only 4 months old, any particular reason why you had it changed out to begin with??

Your board can only handle 2Gb of total memory.
2 x DDR2 SDRAM DIMMs, Dual Channel DDR2 533/667/800.
Check your manual.
