What board do you have? and what are the symptoms? As in there is nothing on screen?
If you are getting three beeps on an intel board with the memory in it means that the memory is faulty (well actually what it is tellign you is taht it can't find the memory) which would account for nothing on screen. So if the above is correwct then you need to test your DIMMs one by one, if none of them work then you will need to get some other memory to test.
hope this helps
I have a DX38BT. My PC will buzz and whir but nothing shows up on the monitor, no USB activity, etc. More or less it starts but doesn't run if you will. I hope you are wrong about my memory because I would hate to be out of 6 GB of RAM. I have tried a each single DIMM (2048 DIMMs X 2 and 1024 DIMMs X 2) and so far to no avail. Currently I am in South Korea, and I don't exactly have a lot access to additional resources. So hopefully we can find a workaround.
Let me know, thanks
