Post subject:  A weird computer problem
Okay,
My computer will not power up (not the one I am using to make this post), but another one which I am trying to get to work. I have RMAed both the PSU and the motherboard. So they both are replaced and is new. Still the darn computer fails to power up. I have even replaced the RAM of two different brand one by one and still the darn thing will not power up. I even place the motherboard on a 4" thick rubber mat to see if the mobo was shorting out, but you have guessed it, still won’t power up! The green diode light on the mobo comes on and the LAN LED blinks. The funny thing is it as if there are no life to the thing because the CPU fan does not even twitch, not once.
The Specs are as follows
1. 2 Intel Xeon CloverTown E3555 2.66Ghz 8 cores
2. 1.5TB HDD space (2 Seagate 750GB HDD x 2)
3. CoolerMaster Real Power Pro 850W
4. CoolerMaster CMStacker 832
5. ASUS mobo DSGC-DW
6. One GeForce 8800 GTX
7. Probably not necessary but, Seven 120mm fans
8. DVD burner of course.
9. 2GB for now due to testing different RAM but up to 32GB RAM.

Any suggestion would be appreciated!

When did this start?

After I build the system, so it really never got used at all.

I think either the pieces you put together arent cooperating (brand issues?), or you put them in the rong places/connected them to the rong parts. Im not completely sure tho, because I dont have much experience with building computers.

I am starting to wonder if the CoolerMaster PSU is just not cooperating as you mentioned. I am fairly sure that I seated all the component properly and in its correct ports, especially the CPU with a golden Triangler edge in the triangler notch on the mobo.

It sounds to me like you have too much plugged into the system and it does not have enough power.

The PSU outputs 850w of power, though. That's plenty for all of the hardware.

It sounds to me more like the PSU isn't plugged into the motherboard properly. The PSU you are using is EPS12V, and I would expect the motherboard is, also. You should have three different connectors (24 pin connector, 8 pin connector, 4 pin connector) plugged into the motherboard from the PSU. If you missed any of those three, the system will definitely not work as intended; the Xeons need all of them. The other connectors should be obvious (PCI-E, peripheral, etc.)

Only other thing I could possibly imagine is ... make sure the PSU input voltage is set at 115v in the US, or 230v in Europe/Australia. But this should be obvious, as well. :\

I made sure that it is plugged in securely and properly, All three is plugged in and the PSU itself is clearly marked on each plug e.i. 4 Pin +12v CPU, 8 Pin +12V CPU, 8 Pin PCI express, etc. so I know I did not plug in the 8 pin PCI express into the 8 Pin +12V CPU on the motherboard or the likes. The voltage switch that you mentioned, the thing is my, PSU does not have these switches let alone a power switch :? . There are nothing on the back of the PSU besides a place to plug in the cord into. On the box however shows that it is indeed made for the US.

Make sure the motherboard doesn't have any extra power plugs on it. My ASUS board has a 4-pin molex connector on top of the normal power connectors. The board won't power up if it's not plugged in.

I am sure that it does not have any other plugs on it, I pretty much filled it up. The computer is now pretty much striped down to barebone trying to isolate the problem and still nothing :x . I forgot to mention that I do not have a faceplate installed, because the backside of the board where all the ports are does not align up with the case. Will that cause the computer not to power up?

No. The worst it would do is make grounding the motherboard components more difficult. (In general, the more direct feeds to ground, the easier electrons will flow.) The PSU should have a fan inside... Does it turn on? Do you have a multimeter [capable of accepting high currents]? I would suggest checking the PSU for proper output levels. I've never seen one without a voltage switch or power switch. That is just bizarre.

The other thing, and it's again very silly... Make sure the front panel connectors are all correctly installed.

Got the computer up and running :D , it was the PSU. Funny because that was my third Coolermaster PSU. So to all that are reading this message: Do not buy any of the Coolermaster's PSU, they do not work, Pass it on to whom you know is in the market for a PSU.

The outlet you used and/or the building's wiring might be faulty, which could kill a PSU.
