RE: Dell Inspiron 6000 (out of warenty) will not turn on.
I had the same problem with the caps lock blinking 9 times after upgrading RAM on my Dell Inspiron 6000. Turns out the RAM I had bought was PC2-6400S. Dell Inspiron 6000 is only upgradeable to PC2-5300 RAM. Check to see if the RAM modules is labeled with PC2-5300 or 6400 part number.
