are fans and other stuff working?
also plug in the speaker in your case (it will beep if you have a problem) , reseat the ram, video card, and cpu.....clear cmos as well...

Nothing like no fan or anything.

You're sure you have the right wires plugged into the power switch header on the motherboard? I've seen a couple of those things that I couldn't really tell the power LED from the power SW.

I don't really get what your saying...
Man I'm stumpted
What about the switch from the ATX case itself does it have anything to do with it?

plug a fan straight into the psu to see if that works....see if the prob is the psu or the mobo...

Hmmmmm.... my power supply doesn't work unless it's plugged into the motherboard, so the fan theory might not work for you. I'd agree with Godfodda, check the headers for the power switch. Of course, if you've done that... my first guess would be the PSU, then motherboard. No beeps seems to suggest that there's either a problem with the switch or power supply. Does your mobo have an LED toward the bottom that will light up if your PSU is properly plugged in and working??? If you do, plug everything in and see if that lights up. If it does, it's your switch or the power headers for all those buttons and LEDs on the front of the case. If it doesn't, then either your PSU isn't plugged into the mobo (believe it or not, stupid ol' me has done that a few times) or you have a busted PSU.

Yodums,
Try other mobo if you got it. Connect em to that PSU. Then you know what the problem is. If it doesn't fire up, then you got yourself a dead mobo. That can happen.
Also, make sure the wattage selector is set to American standard 115- 120V, not the 230 one. BTw, did you just build the system or already built one???
Yodums, I realize this is frustrating, but please edit the profanity out of one of your earlier posts. It's critical on an ATX mobo to have the power switch connected properly. If you have the internal speaker connected (most newer mobos have it built in now), you should get a beep on power up...no beeps mean no power to the mobo or that the RAM is not right. Remember, the mobo must be grounded to the case. If you used brass mobo standoffs and screws to attach the mobo, you should be ok there. I had a brand new mobo that did nothing once. I removed the big main power header that comes from the power supply to the mobo and reattached it securely at least 3 or 4 times until it finally made a good connect and started working....drove me crazy. It was getting enough power through to light up the LED too. Make sure that main power header is securely connected.

The old PSU should be working fine everything was working fine for the past 2 years since today when I switched things around.
I did try a dif PSU from my old case no turn on. It wasn't grounded in the case but that PSU before it wasn't in the case and at the floor at the back of the case and did fine.
Yes my mobo has that light led that will show of mobo's getting power and yes it's on.
I don't know if its the switch because what I did was take my old case put it above the top and just take the power switch connecter and plug it in my mobo didn't work. Although I just plugged in only the switch.
PSU is fine I'm stumpted.

Other mobo is dead.
I don't think its a dead mobo it fired up before then by accident I pulled out the plug for no reason I just wasn't thinking.
I did set it to the American 115v as well.
I system is 2 years although what I did is just readded my card my better cd roms and stuff...

Profanity where?
The power switch should be good everything worked with its original rig for 2 years and obviously the power switch connecter from the front is there and its turn on signal(wire thing) was plugged in I removed it and put it back in to be sure.
I reinstalled every part including ram no power.
The mobo is defintely grounded in the case I didn't not change that.
Yodems,
I am new to the scene, but maybe I can help by saying this. Unplug and unscrew EVERYTHING. Take it all out of the case, take everything of the mobo, and let it sit on your bed, or desk, or whatever, for exactly 30 minutes. Don't touch...don't even look at it. When you come back after 30 minutes, start over from scratch. Put it all back together and see if it works.
Sometimes, we are so worried about the big stuff, that the simple things elude us...
The mobo is grounded in the case?! I don't like the sounds of that!! What exactly do you mean 'grounded in the case'?
Fluid, ATX mobos need to be grounded to the case mobo mounting plate. I don't mean traces or components touching. I've seen where people used only the nylon or plastic standoffs and they had problems. If you use the standard brass mobo standoffs with the proper screws that come with most cases, then the mobo is properly "grounded" to the case.
Yodums, 9th post of this thread (your 6th post) where you say you're losing your patience, you used profanity that some people might find offensive. I was pointing that out to you because I don't want to see you get into trouble in case someone might complain. As a senior member, I have to help keep the peace in this forum.
Hmmmm....This is new to me. I've built plenty of systems and never once have I heard of 'grounding' the mobo to the mobo tray....I mean, it's not like the mobo's covered by a radio interference shield or anything and if you take a look at the base of the mobo you will notice that the small solder pads around the screw mounting holes aren't actually connected to anything - they're just there for protection....
If I was you I would remove the mobo from the tray and reinstall it being careful to make sure the board hasen't shifted causing a short on the standoffs....I say this because I did it many years ago....
Trust me on this guys.
The motherboard is in the case properly.
This computer was bought 2.xx something years ago and it has been working fine till this day.
Grounded yes it is defintely grounded..
I did start from scratch with the motherboard grounded.
It did not work unfortunatly... we'll bring it to the shop tomorrow and get it checked out.
Lets see heres what I did..
From the evening the computer entered my house:
My old computer was dead and I was mainly sure it was the cpu I swapped the CPU from my brothers case which was a P3 500mhz Katmai Slot into my computer no boot. I put it back in my brothers case it booted.
Then I took my slotket with the Celeron chip put it in my brothers case did not work.
OK I repeated what I just did about 2x then I concluded that something like the motherboard, slotket, or chip fried and took things down with it.
OK I told my brother that I needed a new motherboard and chip and a ATX case since mine was KTX to get everything working again. He briefly explained to me that the economy is not strong this year and things were put to hold and I could keep his computer and he'll use his labtop.
Man I didn't want to start taking things from him because I broke my stuff, but I had no choice ok I said, "OK.." He said that don't upgrade the computer anymore and just keep everything the way it is working. I followed up with the line "Yes, I was planning to do that."
I started the "move-out" from my computer to his computer meaning I took parts that were better from my comp to his comp.
I started with the ram. In total 512ram was in and was booted.
Took out the power plug(or I think) and then I added either my video card or my 52x cd rom. I think it was the video card first and then I tried to turn it on. Not working since it did not turn on I suppose I left the power in there and then as I took my video card out to put in his the system turned on for no reason as I pressed the switched like 1 min ago. I pulled the plug quick and then from there I tried switching the card no boot.
And from that moment my system would not boot as a whole.
Motherboard led shows power is going to the motherboard.
I tried reinstalling the panel switches to the motherboard again.
Till now nothing has worked and my next option is bringing it to the shop.
If you have anymore suggestions help.

I know this "grounding" thing is confusing. I've powered up motherboards out of the case just sitting on a nonconductive table surface before. But, twice I've seen where the motherboard was totally insulated from the case and there were problems until some of the plastic standoffs were removed and replaced by metal ones. I think it's for static discharge or something. Dunno for sure. It don't make any sense to me either.
Yodums, another thing that will prevent boot up is not having the CPU fully seated. It has the be one of the following: bad power connection, failed power supply, CPU or motherboard problem, bad vid card or a problem with the RAM. Maybe the RAM or the vid card are not seated? Sounds like you're tried reseating everything. Maybe you static zapped something in the process of switching stuff over?

Yea, if all that's working, I'd tend to agree with batboy, either ya zapped something or something's not seated properly. Those Slot 1 CPU's were always a pain in the @$$ like that, and my Asus Slotket was even worse. I might guess the video card though, based on your description. I just got one of those anti-static wrist straps... even if this isn't the problem with your system, it may be a worth while investment. It doesn't take much to kill a component. They're only about 5 American dollars at the local Radio Shack. Likewise, I got in some anti-static pads to put components on. I swear by both of them now.
Just for the record, in my old Slot I system, I was using an Asus P2B-B, and it came with plastic standoffs from the retailer. I used those and just recently, the board shorted out. It is possible, and I've just recently become very picky about using ALL of my standoffs in putting together motherboards, not just 2 or 3 like I was doing before.
G'luck, I hope somethin' works for ya.
Well lets hope I did not zap anything.
We'll see tomorrow. I edited my post batboy sorry for doing that.
Another day of cpu complication awaits...
Thanks guys.

If you comp didn't boot with the p3 Katami either then the problem is probably with the mobo, RAM, or vid card
unless your brothers comp had bios with coppermine support/voltaage adjustment then the slotket would not work

Doubt it I think I static shocked the motherboard.

By the way recieved my chip at work yet?
Yeah...i got it the end of last week...just got a chance to put it in Sat ....everything seems to be working fine. I think that Golden orb was holding back your OC...that thing gets kinda warm at default speed

The old Katmai never oced well.
If I knew that before I wouldn't have bought the Golden Orb.
That thing ran very cool according to the sensor.
It ran 32 Full Load On Seti.
38 On CPUBurn on hot nights.
I'm using in an old FIC slot 1 board with no temp sensors but just by touch its kinda hot. My guess would be about 35-40 C
Of course I dont have any case ventilation except PSU fan...not really needed for Intel chips at default speed

Ah well with only PSU Ventillation thats probably why its near the 40.
At least it runs good.
