[SOLVED] Troubleshooting really old dead PC. 5 and 6 beeps on ASUS A8N-SLI Deluxe

Everything apparently turns on fine but there is nothing on the screen. It detects a signal but goes immediately to standby.

Initially, before I took everything apart and cleaned it, I was getting 1 long and 2 short. Trying a different graphics card and reseating the RAM did not work. After cleaning the entire PC and reconnecting all the parts, I now receive 5 beeps, and then maybe 15 seconds later 6. Specifically, 2 rapid beeps then 3 short; and 2 rapid 4 short.

I have yet to find out the version of the bios. I don't believe I ever updated it. I can't find any documentation on these beeps. The original manual does not include them.

I have tried resetting the bios by removing the battery and jumping as well.

The CPU is an AMD 64 939 socket. And I just noticed the nforce4 SLI chipset fan is not spinning, maybe something to do with the initial beep code?
