I'm building a killer PC for myself, but I have a problem: The PC won't boot normally.
Configuration:
dual Xeon 2.8Ghz 2MB Cache 800MHZ FSB
Intel SE7525GP2 motherboard
Enermax 485W powersupply
ASus N6500 PCI-express VGA-adapter
40GB + 120GB harddrive
DVD-player and DVD-rewriter
Problem is, with a dual setup it boots, but doesnt get beyond the POST. With a single setup (CPU only in the first socket) it doesnt even power on.
I have the feeling that my powersupply isn't enough for the machine, but I'm not entirely sure...

P.S. 1GB Kinston DDR 400 Ram is installed in the machine

485W should be plenty esp. since it only boots with 2 cpus, what about the RAM? You could try slowing that down to be on the safe side.
Remove the RAM and you should get the beeps for no RAM present.

It should be enough power. I would look at other possibilities:
dual Xeon (Nocona) 110w x 2 (at full load)
nVidia 6500 ~65W (I don't know the exact number, but 6800 == 105w and 6500 is listed at more than 50% of the 6800 but significantly less, so I made a guess)
12w per HD (these range 9-12w, choose high and you are safe)
DVD RW 10w (12w if lightscribe, otherwise 8-10w is standard)
that is approximately 319w, I am not sure of the exact power consumption of your motherboard, but it is below 100w. So unless there is a physical problem with your power-supply, you are well within the safe range.
We run dual Xeons, with top-of-the-line graphics, 5 hard-drives and DVD RW, we do use a 550w, but have used the 450w prior to Nocona (95w prior to Nocona). Because we don't know what customers will do with the machines after they get them, we have to provide enough extra power to cover what users will "add" to the system.
Generally you will not get a full post if you don't have enough power. I would start checking your CMOS settings. Where is it stopping? at boot? is your boot setup right? can you boot on CDROM without a hard-drive? What happens when it stops? does it shut off (this is a sign you are over-power, your powersupply will shutdown.) Is your power supply dual line powered? (separate line of power to CPU/motherboard from the rest of the equipment)

With both CPU's installed the fans turn on, but the board doesn't boot into the BIOS screen.
When there's only one CPU installed the computer only switches on for a short moment and shuts off imidiatly.
I have an enermax Noise taker 485W with a separate 12V rail for the motherboard.

what's it's rating for 12V power? it should be listed on the side of the PSU in amps. *12 for wattage. The cpus, gfx cards, and disk drives all primarily draw 12v power. If you have a psu using an older design it might not be able to fully power the 12v rail even if it can put out enough total watts.
If you have a multimeter, test this by measuring the voltage between a yellow and a black wire of the atx plug on the mobo when you hit the switch. You should see 12v. FOr completeness also test the aux 12v connector, and the red and orange wires of the atx plug (they should be +5 and +3.3v respectively over ground).

18A per rail.
I even have 12.3V when measuring between the yellow and black wires.
So this should be okay.

That sounds like a power issue... but with one CPU you should be well below the power requirements....
I did find the motherboard requirements... higher than I expected. 131w maximum not counting CPUs....
Do you have extra power running to the graphics card or does it take all the power from the PCI-ex slot? I can't find that model with google.
Not sure why it would be giving you power issues... but you can start testing from here. What I would do:
Pull everything off power except motherboard and VGA (no drives, no CD-Rom) and one or two CPUs (or both one at a time). Double check that you have your power set properly on the motherboard. Is there an extra 8pin power that is on the motherboard? (20+4+8 or 24+8)
are CPU coolers firmly attached? if your CPUs overheat the system will shut down, this is a safety state above 70C (or where-ever the CMOS is set to emergency shutoff).
Start from a barebones system

That's a lot to check on, will check it from there. I have asked a friend who has a spare powersupply to bring it with him tomorrow, so we can check that also.
Thanks for the help so far.

Following up on your tips:
I have replaced the power supply with the one I borrowed from a friend.
And it now boots into windows setup, all seems to work now. Also I checked the coolers, cleaned them and reattached them to the board, after checking if there wasn't a shortcircuit near the brackets underneath the motherboard.
Somehow the power supply wasn't functioning as I thought it would.
I will see into replacing the faulty one, since it's only a few months old 
Thanks for the help, now I'm going to enjoy this new power monster!

No problem, I didn't do much obviously. Enjoy!

Finally, decided to get it...
Athlon 64x2 dual-core 3800+
2 gig ram
250 gig HD.
gForce 7600gt ( 256meg )
Antec SonataII case ( piano black finish )
It's nice, everything pretty much works on it now.
haven't tried Oblivion, but morrowind works very well.
now, if I can just find the appropriate analog monitor driver so that I can use the best frequency before I spend some more money on a LCD monitor.

Im planning to buy a pc for gaming. I know a little about computer specifications. Can anybody tell me which computer specification should I buy and which brand. Thanks!

The bigger the better.
2 choices :
- Homebuild/Storebuild, you buy the parts and build it yourself ( or have a store build it to your specs )
- Brand Computers, all in one gaming packages ( XPS from Dell, AlienWare, ... ) that will offer a straight gaming platform.
It also depends on the type of games you want to play, 3d shooters, strategy, RPG, racing games, ...
and most importantly, it depends on the amount of $$$ that you have.

If your budget will allow, a minimum of a 2gig a64 or 3gig p4, 1 gig of ram (preferably 2), and a geforce6800 or better graphics card. Monitor and harddrive capacities to taste. With 2 gigs of ram this should be able to handle all of the latest games, with 1 gig you'll have a bit of a weak spot, but ram's an easy upgrade in the future. If your budget will allow, get a dualcore chip. It won't help much now, but newer games will be able to take advantage of the doubled processing capacity.

Hi, Can Any body tell When we purchase Used Computers Which Things we should check before buying. like Processor, Ram, BIOS etc How we check these.

You should check everything before you buy a used PC.

mr. vivek, i think that due to one of them , this problem occurs. so, plz check the following , i thnk yr problem may be sort out...........
1.Drive failure------ yr drive may be faliure.
2.Boot sector failure........ya phir may be yr boot
sector arises some problem.
3.DOS/Windows file corruption...check all windows files , there may be some corrupted file.
4.Run FDISK/MBR ....for rebuilding MBR (Master Boot Record) or DM.....and if through all above yr problem not sort outed, then give the DOS COMMAND......FDISK/MBR.

Please may someone help me. I am looking for online computer repair classes cheap and affordable cost.
Please can you direct me to the website or an search engine that might help me that way?
I am majoring in Computer Science but I want to improve my knowledge of troubleshooting computers!
Thanks for your responses!

Google for A++ certification, that’s what the A++ is all about. Just general computer knowledge / repair.
The best way to become familiar with the various problems computers / technology face, is to jump in and get your hands dirty (well only if you have an antistatic wrist wrap). Family and friends are always a good reliable source of broken computers. One word of warning once family and friends learn that you know how to fix computers; they will be coming to you for every thing. 
Good luck
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

Is F1 the key for your machine? Different vendors don't all use the same one. I've also seen F10 and Del used to access the bios.
Assuming you're using the right key, one thing that occurs to me is if you're on an older system and using a USB keyboard the bios might not recognise it even if the OS drivers do. You might want to try a PS2 keyboard if you're using a USB one.

Did you mean Compaq? If so, using Google found out that Compaq machines uses F10 to access the BIOS
