Major Problems With Friends New PC Please Help!

My friend bought some parts on newegg to build himself a nice new pc.

Asus P5N32-SLI Deluxe
eVGA 7900gt CO
Pentium D 930
Patriot 2GB (2 x 1GB) 240-Pin DDR2 SDRAM Unbuffered DDR2 667 (PC2 5300) Dual Channel Kit
OCZ Powerstream 520w

We put everything together and the computer wont boot up. The fans and everything starts spinning but the cpu doesnt post at all and their is no video. So I thought maybe it was a problem with the bios being a little outdated for the new processor he bought. We called asus and they shipped us out a new bios chip. We popped that in and still the same thing happens. After trying everything I could think of the power supply seems to have died. It still turns on but the fans inside the power supply wont turn on anymore. The power supply is being replaced by Newegg. I really don't think the PSU was the problem though because the system seemed to be getting power fine when we first put the thing together. I have really run out of ideas and don't know what to do next. The only other thing I can think of is the motherboard doesnt like the Patriot ram. Please help! :confused:
 
Well replace the PSU first and I hope he didn't shimp on that . Were you able to enter the bios at all. As i read your post you couldn't. I am not saying OCZ doesn't make a good power supply but I have read a lot of post were people have problems with these psu installed . no flame intended. The heart of every good system is the M/B / PSU
 
do you have any other chips to try? Specifically a Prescott chip (non CedarMill / non Presler chip)

The board may have come with an older BIOS that doesn't support the newer 65nm chips.
 
we had asus send us a new bios chip. that didnt seem to fix the problem. I do not have any other socket 775 processors to test.
 
its very possible that the motherboard is bad. i have gotten 3 different boards from newegg, all new retail boxes, and they didnt boot. really angered me since i paid for a working retail item, and had to rma which took about a month. the ocz power supply's are great. i have one and its a great unit. do you possibly have a backup computer to test the other parts on? if so you can probably narrow it down. my guess is either the psu or board with the 3rd choice being the ram. try single slots and see if it will boot.
 
I am betting it was his power supply . beings how the fans on the PSU didn't spin up.

I to have had new M/B that wouldn't start up . But working hard at getting into the bios I found the CPU v. to be set to low and other setting were bad also.
 
unfortuantely all the hardware he bought is new technology pci express and socket 775. Im still running 478 with agp so I have nothing i can use to test his stuff.

I tried each stick of ram seperatly that didnt work.

The thing with the powersupply though is it seemed to work fine when we first installed it the fans in the psu worked just fine. Maybe it was defective from the start and just getting worse?
 
he lives 2 hours away in brooklyn. I am probably not going to see him again until the end of this month.
 
When my brother put together his computer (with help from me), the same thing happened.. it 'turned on' but.. nothing happened.. fans spun. As soon as I used the jumper to clear the CMOS, (and then put it back) it started up..
 
as I have that same motherboard, and read the Asus forums, a couple tips:

Forums here, see if any of it sounds familiar-P5N32-SLI-Dlx Forums

1.) make sure the 8 pin EPS is plugged in--imagine you already did, but just in case. It IS required

2.) make sure you try it with the EZ-Plug Molex too--that plug by the PCIe slot. This helps stability for the 9series, and the 7900GT OC could probably benefit from the voltage as well.

3.) are you using the little blower fans for the heatpipes that it came with? If you have decent case ventilation you shouldn't need them, but it wouldn't hurt to test it.

My setup is:
P4 3.73EE 1066fsb
4X512 Corsair at 675
BFG 7800GTX OC 512Meg at nearly 7900GTX speeds
Watercooled
2X120mm crossflow from CPU side to GPU side

I use a Liberty 500W by Enermax, and I haven't needed the EZ-Plug yet. But I do have the 8 pin EPS plug in along with the regular PSU plugs.

Hope it helps eliminate something.

You can also try a floppy drive flash with the 310 BIOS from Asus:
BIOS 310 for P5n32-SLI-Dlx

I tried clearing the cmos 3 times. one of the times I even removed the battery for 30 seconds.

8 pin is plugged in. the ez plug we tried with and without. and the stacker cooling fans we cant use because he is using the new zalman C9500 heatsink and fan

we cant flash the bios because we cant even get the cpu to post. Asus sent us a new bios chip maybe they sent the wrong one?
 
Asus had a great deal of problem with the 209 BIOS, check on the BIOS chip and see what it says on it.
 
it may be possible that the power supply simply can not produce enough power for the system.

i hd the same problem with a friends pc. what we did was google how to link power supplies, but what we did was make a psu turn on without the mobo. WARNING!! the psu must be connected to a device before turning it on or it may blow up/break.

what we did was hook the hard drives and video and dvd drive on one psu and the mobo on the one in the case only and the psu turned on. on a modern system you need a 400 and up psu. mine can deliver 400 watts no probs. (been tested on toms hardware.)

this confirmed that we needed a psu that could generate more power.

later

Easy
 
Take the mobo out of the case and try to power it on, maybe it's shorting out in the case or on the offset screws. Sorry if you've already tried that, I didn't see it posted and I figure I could maybe eliminate one more thing. Good luck.
 
well my friend received a new psu in the mail from newegg he also exchanged the ram for some OCZ ram. we plugged both in and the pc still did not start up. so that leaves either the motherboard or the video card that is causing this nightmare. I am gonna see if I can find an old pci video card laying around my house so I can mail it out to my friend.
