New rig, but nothing on the monitor!

[Chiss]

Hi,
I just finsihed building my new rig:

Motherboard: Gigabyte GA_M59SLi-S5 nForce 590
CPU: AMD Athlon 64 X2 (AM2) 5000+
RAM: Corsair TwinX XMS2 800DDR2 2048Mb
GPU: Gigabyte 786Mb 8800GTX (PCI-E 16x)
Audio: Creative SoundBlaster X-Fi Fatal1ty FPS
PSU: Tagan TG800-U25 800W
Monitor: Samsung 930BF

Ive checked all the cables have been plugged in properly
and all the fans are going fine.
There are no beeping sounds at all.
I've tried both ports on my GPU, using both the Analogue and DVI cables.

I've disconnected all the drives and cards and placed the motherboard on a piece of card board, with only the CPU and Heatsink, 1 stick of RAM, the PSU, the GPU and connected up the monitor and ps2 keyboard and mouse. but still nothing shows on the screen.

Anyone have any other ideas?
Any help would be appreciated

have you tried scrolling through the inputs on the monitor's menu and selecting each/the correct one?

if there's no beeps it might be the motherboard itself.. start RMAing things

Have you tried each stick of ram in every slot or just 1 stick.

Sounds like motherboard to me. or the cpu isn't in right..

Yes, still nothing shows, whenever I use the DVI cable it asks for the analogue and when I use the analogue it asks for the DVI.

I take it you've tried the GFX card in both PCIe slots?

Have you tried just one stick of RAM in slot 1?

Are all the power connectors plugged into the motherboard? Some mobos need an extra molex power connector on there.

Are the fans spinning up?

Tried replacing the cpu, still no go there...

Could it really be the motherboard? The fans are all running fine on the cpu and on the gpu, powers must be running through it?

Could be the video card - try another if you have one. If it's not giving the passing post beep it could be CPU/RAM/Motherboard.

Detatch as many non essential devices as you can (hard drive/dvd/floppy/sound card) and try again.

Yup Ive tried the different slots and tried the ram in different slots, no go.

All power connections are plugged in, the 24 pin, the 8 pin and even the extra one down at the bottom that looks like a cd-rom power point, but is in in fact "extra power" for the pci-e cards.

And all the fans are spinning.

Tried a different card, my Gigabyte Nvidia 7800GTX, and same thing occurs.

Question:

If I remove all the RAM and there are still no beeps, does that mean the motherboard is probably the problem?

[z80]

Have you tried without drives/sound card?

If you remove the RAM it will likely give an error beep during the POST

[Chiss]

Thanks for your help everyone! I've decided to RMA the motherboard.

Apologies Chriss - just re-read your initial post and noticed you already mentioned you had removed the cards/drives.

Hope the replacement board sorts things out for you.
