HP Proliant DL380 G3 Troubleshooting

[ComTech14]

my DL380 G3 will not post. it has 2x2GB sticks of ECC DDR1 CL2.5 Ram in Slots 1 and 3, No GPU, Unknown CPU, but it has two cpus, populating both sockets. I have already reseated both.

 

when it tries to boot, after about 5 - 10 seconds after i press the power button, it emits a 5 or so second long beep, followed by 2 or seconds of silence. this is repeated. also, the system health light on the front turns red, and the amber memory lights illuminate for all memory slots. the guy i bought it from had it running when i got it, so i have no idea what is causing this. any help is appreciated.
