P4 not booting

[Calab]

Mainboard is an Asus P4C800E-Dlx. CPU is a 2.6Ghz northwood P4. Memory is 2x
OCX PC4200 256meg. PSU is a Corsair 680watt modular unit. Video card is a
nVidia 6800 AGP card. All mounted in an Antec 1200 case. OS is Windows
Server 2003 (shouldn't matter though).

Right now, when I turn it on, the fans spin but there are no beeps and the
monitor never sees a signal. Last thing I did was to change settings in my
BIOS to defaults, memory speed, CPU speed, etc.

I've already tried to reset the BIOS by using the MB jumper and removing the
battery. No change.
I've removed all hardware except CPU and 1 stick of memory. Still no boot
when powered on.

At this point I'm assuming that the mainboard is dead. The PSU is only a few
months old and the Northwood P4's are pretty rock solid.

Any ideas what could be going on here and how to proceed?

Perhaps the RAM memory is failing.
Test with other memory, and try to disconnect and connect the Video
Card, Memory and before clear CMOS.

If you have other cards disconnect it, the computer must turn on only
with Motherboard, Video Card, Memory, and Processor, the other cards
there are not necessary for to turn on, maybe cause the fail or
something incompatibility.

If everything its ok, and your PC turn on test connecting one card at
time, and verify that the PC turn on correctly.

Excuse me, if I write bad but newly I'm learning english.

Remove the memory and listen for a beep code.

When my memory died recently, the computer would not beep. Pulling
the memory, gave a beep code, telling me the processor and the motherboard
were still doing something. (If it beeps, then the processor is running.)

Also, visually inspect the ICH5 Southbridge for a burn mark.

It would still be worth trying a different PSU. Obviously, even quality
brands can fail.

Your english is fine. I wouldn't have seen your post if CB hadn't replied
though. Many folks here filter out GoogleGroups postings.

Thanks for the help!

Thanks for the suggestions folks.

I've tried a second PSU. No change at all. Power LED on mainboard lights up
just like before.

At this point I have the PSU, mainboard and CPU installed. No vid card and
no memory. When I power up I still don't get ANY beeps. CPU and PSU fans
spin.

Next is to pull the MB out of the case and test further. Not sure what I can
do. I've got no spare CPU or Socket 478 mainboard.

Looks like it's time to retire my PC into the server role and get me a new
PC!

Looking at 4gig of PC2-8500 memory, Intel E7200 CPU and Asus P5Q-E
mainboard.

Ouch!

Nope... no signs of anything wrong on the board. Its out of the case and on
my bench now. PSU, CPU+Sink and mainboard. Nothing else. Speaker makes no
noise at all when it's powered up.

I'm betting it's the MB. It is five years old.

I was in a similar position recently with a P4/mobo that I was given. Both
went in the trash. :-(

Every cloud has a silver lining. ;-)

I have P5K-E (WiFi-AP), I must say I like Intel chipsets with Intel CPUs. To
me it doesn't make sense to go any other way. Reviews seem to agree that
there's little advantage with the P45 over the P35 but if you're buying new
and there's not a huge difference in price....

I'm waiting on an E7300, hopefully it'll be delivered today. A nice upgrade
from my current E4500 (that's running @ 3.32GHz), it has a 10 x multiplier
and I'm hoping will run on a 400MHz FSB for 4GHz.

Cheers, and good luck with your new rig.

Hmm, looking at Asus' page for the P5Q-E:

http://asus.com/products.aspx?l1=3&l2=11&l3=709&l4=0&model=2267&modelmenu=1

I see that they quote (twice):

"100% High quality Japan made conductive polymer capacitors! (5000hrs VRM)"

5000hrs? Say, what? That's only 208 days! Crappy Taiwanese ali can electros
with bad electro fomula will do that. Youy'd expect to get 5000 *days* from
Japanese polymer caps.

That is 5000 hours, at a temperature far higher than would normally be
experienced inside a computer case. When the Arrhenius equation is used,
with the right scale factor, at more reasonable case temperatures, this could be
100000 hours (or some equally large number).

What they could do, is take ratios between the performance of the old caps
and the new ones, and say something like "new caps 10x more reliable than old
caps at 45C". Still meaningless, but that is the essence of marketing

I didn't realise that the rating was at rated temp, it's not made clear in a
way that the average punter can see.

Somewhere on teh intarweb "kony" typed:

Contrast that with 'lytics that tend to have 2000-3000 hour
ratings. Plus, when running significantly below their peak
temp rating, typical polymer lifespan is greatly extended,
moreso than with electrolytics if all else were equal.

Like I just said to Paul, I didn't realise that the rating was at max rated
temp. It's not obvious (at least to me). I read the "VRM" to mean "Volatge
Regulator Module" (an annoying usage in these days of most VRs being
board-mounted) and assumed that meant the MTBF to mean "in normal use".

My bad.
