After scrambling to find the solution, I came across these posts.<br /> <br /> For me, my HD would not spin up however the three lights would illuminate, and that was it. The solution in my case was that I forgot to put the ram back after I swapped boards. After I put the ram in, it booted up gloriously.<br /> <br /> My suggestion to you guys is to check your ram--be sure it is seated properly and works. Maybe, if you have spares, swap it out with a different stick and toggle which memory bank it is installed in. Maybe the ram port is bad.<br /> <br /> To the person who put in and took out the sound card--could it be that this re-seated the ram stick the first time you did it?<br /> <br /> Best of luck. text/html 2004-08-16T09:54:16-05:00 Dan Bebber http://www.hardwareanalysis.com/content/topic/16448/#172061 I've got the same problem, but in this case the fan is working. Just get a blank screen, three green lights (numlock, capslock, and the one next to it). Machine is Compaq Armada E500.<br /> I don't have a solution (yet), and your message was posted a while back so doubtful if this thread will reach a satisfactory conclusion. text/html 2003-11-28T19:12:31-05:00 Richard Lovesy http://www.hardwareanalysis.com/content/topic/16448/#0 The darn thing working fine one day<br /> Attempted to switch on following day and the only sign of life is three lights, namely capslock, numlock<br /> and direction key lights.<br /> Screen is blank, floppy drive won't work, cd drive won't work, cpu fan isn't running.<br /> If left on cpu overheats.<br /> <br /> Anybody got a clue?<br /> model is compaq armada e500s
