Ok so this might sound like a strange requestiion (intentional spelling) but i've got a problem in a system that's being build for a fren.

So we're building this system, and all of the piping, wiring, setting, etc. is done. and we boot it. it powers on (hard drives spin, DC pump pums, green light on mobo is on, etc.) BUT there's no picture coming through the video card and there's no POST coming out of either the PC speaker or the default audio-out.

(Yes the 4pin is pluged in, yes the main power is pluged in and we even tried plugging in the EZplug thing that routs extra available power to the PCIx slot.)

So here's the question, anyone have any clue what it might be? or any way to fix it... any help would be gratly appreciated...I know i spend a lot of time lurking on this forum and just recently finaly signed for an account but if you can help i'd be much obliged.

I would start by booting it up with the minimum components and air cooling. It could be a bad stick of RAM - if you dual channel boot it up with only one stick at a time.

BTW, the P5WD2 mobo has PCI-E slots, not PCI-X (PCI-X is not short for PCI express).

yah the PCIx/PCIe spelling is my bad, sorry :-(. .. would the system really not POST with bad RAM tho?

Well, with bad hardware almost anything is possible - I had a bad socket A board that burnt (with smoke and eveything) a CPU.
Bad RAM is common enough, that's why I mentioned it. If you have another graphic card I would try that too.

hm..you think a system will POST if I remove all external components? (i.e.: just run the mobo dry, maybee with just the CPU?)

Hi Aselus!

Thanks for joining pcapex!
Now let's see what i can do to help you through this dilemma.......

Okay, to my understanding when you turn on the system. You get power....fans etc spin up but there's no post beep or any beeps for that manner.

Plus, your watercooling this pc. Did you by chance leak test this system for at least 24 hours before installing the hardware?

In order for me or anyone else to help you resolve this problem. It would be best if you post all your hardware in this system. Just knowing that you got a asus board isnt going to cut it. What about your psu, ram, video, waterpump, etc......Without knowing your hardware it makes it much harder to give a proper diagnosis of the problem.

Now that we got that out of the way......here's a couple of tips to possibly help you in solving the problem.

#1 First thing to check is to make sure the motherboard isnt shorting out somewhere in the case. It might be wise to pull it out and make sure all the standoff are where their suppose to be with no extra's.

#2 reinstall the motherboard and only connect cpu, memory, and the video card. Plug in your monitor to the video card and power up. Does it post or signal a beep code?

#3 I know i forgot to mention it, but reseat everything cpu, memory and video. Sometimes it happens when their not plugged in all the way.

#4 It would have been best to test the components before you went watercooling. Cause now its more of a pain in arse to deal with this.

#5 make sure the board is in single card configuration and not sli.

As for the EZ Plug.....That only needs to be plugged in if your running SLI. If your not then its not necessary to run a molex connector to it.

Give these a shot for now......and fill us in on your hardware if this doesnt solve the problem.

Good luck.....

I'm not sure if it will post without ram, but if all thats attached is - CPU / Ram / Vid card (as it dont have onboard) it should post just fine like that , barring any bad parts.

EDIT : looks like RnM beat me to the post ( punch ) . One more thing so as not to have to remove / install / remove etc etc is to bench fire the system out of the case, and do all testing that way.

Btw just wanted to say thanks for all the responces guys! and I'm more then glad to have joined pr/pcapex, been thinking about it for quite some time now and it's more then an honor to become a part of all this.

Yes the system was bled/leakproofed for 24+hours prior to running it on for the first time.

Here's the parts list for the system being built:
Non-cooling HW:
Case: Thermaltake Armor JR [btw to anyone looking to work this thing into a water cooled case, be dremel ready, it doesn't exactly take to some things happily..pretty crapy case design i think, might review it after this build is over]
Psup: Hiper Type-R 580W Modular
Mobo: Asus p5wd2
GFX: eVGA GeForce 7900GTX OC
RAM: Corsair 2x512 DDR2-1066 RAM
HDD: RaptorX 160GB

Cooling parts/blocks/etc.: All pipes/fitting on this machine are 6mm (1/4")
Pump: Thermaltake 90 L/H 12v pump (inline)
Resevoir: 5.25 bay 250cc
Radiator: Thermaltake CL-W0002
CPU block: Thermaltake CL-W0010 LQ 208
NB block: Cooler Master RL-SUC-CNU1 NB-AQUA
VGA block: Koolance VID-NV2-L06
RAM block: Koolance RAM-30-V06 [yes actualy installinga ram waterblock on this, thought since one is out to see if it actualy makes any real difference or not, since noone else seems to have reviewed it yet anywhere, review of this to come also.]
HDD Block: Koolance HD-55-L06
Flow Indicator Accessory by thermaltake

Waterflow cycle: Resevoir > Pump > VGA > CPU > radiator > NB > HDD > RAM > Flow Indicator > Res.
#1- I scowered the mobo a few times over last night and didn't find anything wrong with it.
did #2, and got no responce, even tried it with the pump running off of a different PSUP on the side. Com[puter turns on, no POST(beeps), no image from VGA.
#3 - Will try to reseat might take some extra effort with the pipes on there ;-)
#5 - yes there is only on PCIe card in this, i don't think this mobo even supports SLI

Problem has been fixed. It was the RAM in the slots it was in, for some odd reason it didn't like the A slot, after migrating to the Bslot everything now works fine...researching why the slot's not working, thank you all who helped, it was greatly appreciated.
