P4C800-E Deluxe No DISPLAY on boot

[croc_]

System starts, all lights and fans are on, hard drives spin, cd drivers scan, no display.

Tried a 9800 pro in the agp.
Tried an ATI Rage 128 in the pci slot.

Nothing. Cleared CMOS. Nothing.

Unplugged everything but the motherboard and HD, NOTHING.

I am prolly missing something obvious. Any suggestions?

See my sig for system specs.

The powersupply is a 250w dell psu, which worked fine with the dell mobo. That is the only thing that has changed, the motherboard.

HELP!!!

[Thrax]

uuuuh ooooh.

That might be a dell PSU that has swapped power leads. Not to scare you, understand.

I would SERIOUSLY suggest a better PSU.

[croc_]

I have an enermax 460 on the way. This was just to get it up and running till the new one arrived. So you think that is the culprit? I mean ... it starts ..... if i wasn't looking at the screen I would think it is working.

UGH ... so troublesome ..... I guess I will look around here for a different powersupply. Could it be something else?

[Thrax]

Yeah, possible.

But I can't think of anything but:

<font size=6 color=red>OMFG, CHANGE THE POWER SUPPLY</font>

To be honest.

[croc_]

OMFG, yes ... obviously .... it was the only one available to me ATM CALM DOWN :P

I might drive 40 miles right now to pick up my friends spare 450w kingwin. IF THAT IS THE PROBLEM, otherwise I don't want to drive 40 miles to find out its something else.

[Thrax]

I was just saying, that's all I can think of ;D

[croc_]

ok .... well ... I am driving .... I will be back in about an hour -_-

[TheBaron]

no dell uses all proprietary components. that PSU wont work with anything other than a dell board. assuming you're lucky, it didn't fry anything

[keto]

Also, you plugged in the video card to the PSU? I have the same mobo and it booted up fine first and always so far, I'll be following closely. Dell sometimes changes the lines to the ATX header to a diff configuration, I would NOT plug that in to the ASUS at ALL

[croc_]

Too late haha .... well .... yeah i tried an ati rage pci card also .... that didnt work either .... SOOOOO now I am driving 40 miles to pick up a 450w psu to test in my system, to see if i didnt fry it.

[Al_Capown]

Good luck and God's speed.

[Geeky1]

did it work before, or is this a new system build and this was the first time you powered it on?

[croc_]

die al, and geeky: new install, first time (all the components except mobo were in the dell poweredge before, and all operational)

[Geeky1]

Well, I've got bad news for you: I'm betting you killed the board. 99% sure you did.

Dells are extremely proprietary, and their PSes have different pinouts than a standard ATX PS. If you plug a Dell PS into a non-dell board or vice/versa, you're likely to kill the board, and possibly the power supply.

You may have gotten EXTREMELY lucky and not had the board die, but I doubt it. I'd just hope it didn't kill anything else in the system, if I were you. The only way you'll know for sure if the board is intact is to borrow that PS.

[keto]

I have visions of a scorched 9800P eek

[Geeky1]

Yah. What I was thinking is that if the pinouts on the PS are off, the voltage regulators for say, the AGP slot, may have recieved a voltage other than what they were expecting (e.g. 5v instead of 3.3) and let too much voltage through to the card, which would probably cause the card to go "poof!"

*mumbles somthing about RMA and being impatient*

Yeah, board is toast, everything else is fine. I am going to call newegg and ask if I can drive it over there, since I live so close.

I knew I should have waited, but I was too excited -_-

I knew Dell was proprietary for their stuff, but since the PSU said ATX, I ASSUMED THAT IT WOULD CONFORM THE THE STANDARD. **** Dell. Why label something ATX and use ATX connectors when its NOT the same? Use different connectors. **** ******* ***** ** **** Dell. IT SAYS ATX ON THE SIDE. Ok .... I am done. Thanks for the help .... even tho it was too late.

Last time i say anything nice to you, evar.

You know I kid AL, I <3 u. You know in grade school, when a girl liked a guy, she would be mean to him? Yeah ... so ... umm ... wanna go out for ice cream sometime?

If I had a nickel for every swear word used there... I'd have enough to pay my visa card this month :)

NEVER EVER use a Dell PSU on a non-Dell based system. Both use the standard ATX 10x2 pin connector, but the Dell PSU has a different pin-out design that doesn't conform to the ATX power standard.

IE the Dell PSU's lead 13 is really supposed to be lead 10 on standard ATX PSU's. You can see how the board would fry if the PSU's lead 13 carried a voltage of 12V, but the board's lead 13 was expecting 3.3V. :(

Well, in my rush to get my NEW SUPER DUPER TOAST-E DELUX motherboard up and running I picked up the PSU, saw ATX, looked at the connector, plugged it in - fits - and turned it on, no post, no anything. OH WELL. I blame Dell for mis-labeling their stuff. I am always right! -_-;;

Just as a little example of what happened, here's the discrepancies:
Pin ATX Dell
1 +3.3 +5
2 +3.3 GND
3 GND +5
4 +5 GND
5 GND PWR-OK
6 +5 +5sb
7 GND +12
8 PWR-OK -12
9 +5sb GND
10 +12 GND
11 +3.3 PS_ON
12 -12 GND
14 PS_ON GND
15 GND -5
16 GND +5
17 GND +5
18 -5 +5
19 +5 empty

You have to give them a little credit. They got 2 out of 20 right, so that's 10%, right? They basically just put voltage to all your grounds and grounds to all your voltage, and then shorted PS_ON and all voltages to ground.

[keto]

lol after looking at that, croc, count your blessings it was only the mobo that died

[croc_]

that chart made me sick to my stomach......

[drasnor]

It's almost like they designed it to kill other equipment, but don't quote me on that.

[Al_Capown]

It got me all razzled up down there.

I vote Dell off the island. They are the weakest link. asdfaskldgjsldkgjasldkgjasl;dkgjasl;kdgjasl;dkgjasl;dkgjasl;dkgjasl;djkg im so mada iasdfa fasdf;asjd f************* asdf asdlgas

[Geeky1]

drasnor, it sure looks like that to me, too. and it wouldn't surprise me if they did, either.

[Optimus Matrix]

I know this may not be your problem but i had the stupidest thing happen with my p4p800. I hooked up a new hdd. so i plugged everything back into the back of the computer and i pressed start and the damn thing wouln't even post no beeps, no display or anything. the hdd spooled up but i could not get this display to work. I thought i fried my video card so i start messing with that and i figured i'd unplug everything in the back so i unplugged my usb cables turned on the computer and the damn thing booted right up. I have no clue what the hell the usb cableskeeping my sytem from booting but i just put them in different ports and it's worked perfectly ever since

[Al_Capown]

No croc_'s a goon :P. He plugged a dell psu into a non dell motherboard. Never will I let you forget about this croc_ :D

ha, i'd pay to see that

how much? :scratch: perhaps a deal could be worked out...

Hi all,
I have the Asus p4c800e-deluxe MB with the Intel 3.4 Processor. Ram is 2 Corsair 512mb (1gig total) ddr 400, graphics card is the nvidia5950 with 256mb of onboard ram. I had a similar experiance and am hoping someone in this forum can help me pin point the problem before I kill another one lol.
The system has been running smooth as ice no problems for about a month. One day -no boot. first thing I did was suspect the graphics card since evrything else seemed to be starting up. then I realized that I did not hear the POST beeps. So I took out the ram. 3 beeps. (that tells you that you have no ram,lol) Thanks! Anyway I checked all the wiring resest the ram and even reset the processor, no beeps or display. A couple of on and offs of the power supply and it starts up no problem. So I put it back together plug evrything back in (usb *&%# devices). No boot again so I am perplexed, however now the power supply wont power on. hmm, theres the problem.

I replace my power supply (ASPIRE ATX-AS520W) with a new one from Thermaltake 550 ATX machine powers up first try and runs,fantastic I think. wrong second powerup fails. Nothing was shorted as far as i could tell, and as youll read on I dont think anything was. At this point I took my processor and ram to a friends house where I put them into a different machine and they worked fine. So the ONLY thing left was the Motherboard. I went and purchased a new one. It was a gigabyte blah blah blah 800fsb 99bucks at comp usa. I returned my MB to newegg for replacement/repair. I ran the gigabyte for about a week. No problem. Then on a reboot MB is shot again. no display no beeps. I did reset CMOS by removing the battery on both MB.
I am a hardcore Quake player and do stress this PC during gameplay. I have a 6 inch fan inside the front of the case a 4 in the back, a fan comes with the 3.4 processor as well as the graphics card and the PS has two fans on it which i keep cranked. The only potential flaw i see is no heat sinks on the ram. Any one have any thoughts on this? I should be getting my repaired/replaced MB back from newegg soon and REALLY dont want to fry this thing again...
