I press the power button and I hear two quick little beeps, a pause,
then six longer beeps, all the beeps together taking about three seconds.
The following page documents the POST beep codes and the diagnostic
lights on the back of the motherboard:

The diagnostic lights are lit as follows:
A,B,D: green
C: yellow
I just noticed that before the lights go into the pattern above, they
briefly (1/2 second) show the following pattern:
A,B: green
C,D: yellow
which has the meaning "Memory modules are detected, but a memory failure
has occurred." As I mentioned previously, the RAM sticks passed
memtest-86 in another computer.
Sounds like you lost the motherboard.
The beep code for six beeps (or should I also count the two quick little
beeps?) indicates "8042 Gate A20 cannot be toggled" and "The keyboard
controller failed its test".
The lights indicate "Microprocessor has failed a BIOS test."
