I did not find the site until I had problems and everything is already in the case, but I've redid the cmos, removed and replaced the video card, checked for jumpers, etc.

I've read the common problems, and the embarressing moments and did not find my problem per se.

I have an Antec sx1040ii case w/ 400 w, asus p4c800-e mobo, p4 2.8 ht, seagate sata hdd, crucial 512 3200 ddr400, plextor 8x dvd-rw, liteon cd-rw

Originally tried to boot with registered ram, got the 3 beeps. Replaced ram w/ unbuffered and no beeps. Monitor was on other computer and works.

Any suggestions, any assistance appreciated.

Thanks in advance,

Welcome to the Forums kydan47 🙂 Your 2.8GHz Pentium4, is it the new Prescott version? If so, it would be called 2.8E. Asus's CPU-support finder shows the board needing the 1014 BIOS or later, to support the 2.8E. I'm not sure whether or not it'll kick over with the 2.8E in it, until the BIOS has been updated. If you know what the BIOS chip looks like on your motherboard, check the label on it and see what version it's got from the factory.

If you're in the Catch-22 situation where you can't update the BIOS until you have a recognized CPU, then one solution would be to throw in a bottom-of-the-line Celeron just long enough to get the BIOS updated, then sell off the Celeron after it's served its purpose. A local computer shop could do the deed for you too. Alternately, you could hit BadFlash.com and buy a BIOS chip with the updated BIOS already on it.

That's all assuming that the problem is, in fact, that you have a Prescott and it is too new for the BIOS to figure out. If that's not the case, then double-check that you've got your ATX12V cable plugged in, it looks like this.

Hope that helps some 🙂 Good luck!
 
Thanks for the invite, mechBgon;

I don't have the prescott 2.8E. I have the 2.8C.

I checked the 12ATX cable and it is securely installed. I have a small "SB power" green light that comes on. The cpu fan comes on also, so I'm guessing that I'm getting power.

I keep thinking there must be some type jumper that I haven't moved, or something.

Thanks for the pointers.

And if that doesn't work, here's a long-shot: if you have some low-rpm case fans plugged into the motherboard's 3-pin fan headers, try unplugging them. I hooked up an Enermax thermally-regulated 80mm fan to my Asus A7N8X Deluxe and it had the symptoms you're describing. The RPM signal from this slow-turning fan was evidently so low that the mobo was boggled by it at start-up 😕 I unplug the fan from the header, and the system resumes normal operation again! 😛

The other item that springs to mind is that if you have a high-end video card that calls for a four-pin power connector to plug into its circuit board, that's something to check. Radeon 9600/9700/9800, GeForceFX...?

Also, is the RAM confirmed to work in another system?
 
Reseated the graphics and memory, no change.

The ram has not been confirmed in another system, but prior to the memory, the bios warned of being unable to find the memory with the beep, beep, beep.

I do have the ASUS 9600xt graphics card, but I can not find any kind of power hook up to it. It does have its own fan that runs when the power goes on, but that must come through the slot.

I did have a silencx fan hooked up to the mobo, pulled the plug but it did not make a difference.

I would not have thought of these. Thanks for helping me to eliminate them.

Hmm... if your new RAM is a pair of 256's then you might try one at a time. You might also try the bare essentials with no drives hooked up. Also, could it be that one of the LED plugs is off by a pin, and is leaving an open connection across the Reset Button pins? You could pull all the case wiring and just tickle the Power Button pins with a screwdriver tip to check that.

Ahh, one other thing crossed my mind: could the keyboard be plugged into the mouse port? I did that the other day, plugging a keyboard in by feel. That system did POST but it wouldn't load Windows.
 
No..the mouse is mounted to the mouse and the keyboard to the keyboard.

Since it is dual dram, one at a time will not work. I did try removing one, and doing the power, but it did not make a sound.

Took out the second stick and it began the beep, beep, beep for failure to find memory.

I think the leds are correct. I had contacted ANTEC and they indicated that the white and black were the grounds and the colored wires were the positives.

That said, I can turn the power on with the switch in back followed by the power button, but if I want to turn it off, only the switch in back will turn it off.

Is there a way to test the reset by pushing the button on the front?
 
Was searching Asus and found the following Q & A.

I heard two beeps during POST, but all the device are installed properly and the system also boot up successfully. Can you tell me the meaning of the BIOS beep sounds? Is there any error occurs during booting?


Normally, there is no beep during POST unless you installed an USB device. The beep sound means the number of usb devices present. For example: You will hear two low beeps if you install two USB devices. However, you will hear one loud beep if no hard disk is connected to the motherboard.

For users who used to debug from beeps or POST codes, we have a smarter solution --- ASUS POST Reporter. It gives you voice POST messages to inform you of system events and boot status. (Please note that only some ASUS motherboards have built-in ASUS POST Reporter feature)

! Seems that there is not supposed to be a beep on post unless I add a usb!

The reset and power buttons are momentary-contact switches, so you could test them with a continuity meter to confirm that they show a connection only while you physically hold down the button on the case. My meaning regarding the plug-in thing was more along the lines of Asus sometimes either goofing their silk-screened markings, or just making them confusing. For example, look at this pic: link From the silk-screened markings on the mobo (another Asus), you'd think this was the right position, but for some freaky reason, the upper row of silk-screened markings refer to the bottom row of pins, and vice versa 😕 So you might check your plug-in work against the diagram in the manual if there could be any doubt on this.

Thanks for trying the single-stick thing. I was wondering if the BIOS could've gotten corrupted... you could try the instructions for BIOS recovery that start on page 4-4 of the manual. I realize they show the system displaying messages on the screen where your system doesn't show anything, but you could simply try putting the mobo's CD into the drive and then firing it up, and let it have a few minutes to do the update if it wants to, then restart it.

If you didn't re-seat the CPU itself in the socket, I've seen a few people get results with that too. Good luck! 🙂
 
Thanks for hanging in there mechBgon!

I'm debating between picking up a new video card and taking it to a shop. The cost of the card would be just about the same as the shop (I would hope), and if it is not the card, they could probably find the problem. I would be guessing. They would have a card around.

If I get an inexpensive card, and it did not work, then I'm thinking to take the whole thing apart and try again, including the outside the box startup.

Thanks for your help.
