need major heelp with first time DYI machine

here's a run down of my hardware

DFI lanparty D mobo
AMD 3800+ venice
Corsair 1024x2 3200 PC memory
evga 7900 GT
WD Raptor sata 10k 74GB
NEC DVD/CD R
Just PC JPC-FP500S PSU
Thermaltake Aguila


and heres my issue:

all fans power on, the case LEDs are up and running, however, no video signal to my monitor. its just blank. no beeping, no weird error noises, nothing. the light that should be green on the monitor remains yellow (no signal)

my monitor is an analog connection, however, the card has only DVI, so i have been using and trying both the dvi slots and the dvi converters. no difference. monitor was working fine the day i put the machine together.

the mobo diagnostic lights are also red.

've installed everything, reseated everything a bunch of times. and tried hooking up only essential hardware (mobo, memory, GPU, CPU, PSU) and rearranged the memory various slot configs. still the same problem persists

on a lesser note the CD drive doesnt want to open either. go figure.

please help. 'll be forever greatful.

Or maybe your fried your motherboard. This always happens and people realize because you can't feel the shock. And if that's the case, I would say not a powerful enough psu for your graphic card. Trying it on without the GPU installed and see what happens?

Also, set it up on a table, outside the case, to make sure it's not a problem with the installation on the case.

Might sound stupid but have you got a good connection on the psu plugs to everything? i.e. Mobo/Graphics card.
I also tend to do as mondoman suggested, re-build outside the case, could be an earth fault somewhere.... take it from there
