Close it up, stand it up, and see if the clicking turns into a diff sound... I have no real idea what it is, but my suspicion is your CD drive trying to spin the disk inside and since it's on it's side the disk may not be catching the spin...

I might suggest opening a new forum and briefly describing your problem with a link to this thread. We need more minds on this because I am no expert and I know for a fact there are more intelligent troubleshooters out there. I'll continue to supply what information I can, but you might be best getting a second opinion on what's going on...

This same forum. Open a new thread on Tom's and link to this thread. People seem to be neglecting this thread so reopen it and link them to our discussion here. Those lights indicate a memory problem. Do you have any other memory sticks? If not, take one out and try booting with just one DIMM filled. If that doesn't boot, take that stick out and put the other one in it's place. If that doesn't work, you seem to have two faulty memory sticks.

The same way you opened this one to begin with. "Ask the Community" Then type a brief description of your problem/s and make sure you link to this thread so they don't have to reask you all the same questions and re-troubleshoot all that we went through.

You're going to have to appeal to the ancients on this one. It's some old technology that, I assume, a lot of the folks on here are unfamiliar with. You'll have to find someone that's been around a while with some experience. Maybe seek out the billboard section and see about PMing one of the top responders...
