I just assembled my computer with an abit at8 32x mobo.  I'm running an opteron 165 on it.  It turns off immediatly after it powers up, I don't even get a post screen, but the built in post code on the mobo is an 87 which says check cpu voltage in the manual.  I've cleared the bios using the cmos jumper, and have tried hitting insert on startup, but I keep getting this error, any suggestions?

Does the post code on the LED actually say "87" or does it say "8.7" with the decimal lit up as well?\n\nIf it's "8.7", then the system is hanging while it's checking the core voltage, not telling you to check it. POST codes tell you the instruction the system is attempting to carry out when it fails.\n\nIf it's "87", then it's hanging as it tries to assign IRQ's to PCI devices.\n\nRegardless, I'd start by ripping out every component other than the basics (CPU, Memory, Video card), as well as re-installing those components to make sure they're all seated properly. See if you can get it to POST at that point. If so, proceed to add individual components one at a time, attempting to POST each time you add another component. I'd also check to make sure your front panel connectors are installed correctly to the header - PWR, HDD Activity, Reset SW, etc.\n\nAs a side note, I've heard about some motherboards having issues specifically related to the main connector of the Power Supply. Is your power supply's main connector 24-pin, 20+4-pin, or 20-pin with a 20-to-24 pin converter? If it's the latter, that could be the problem. Some 24-pin mobos just won't work right with a 20-to-24 pin converter. It could also be a voltage issue with the power supply itself.

Well, if your CDROM worked perfectly before, and than dropped out without anyone setting the BIOS, then I might say that you have a glitch in your Mainboard. However, it could also be a specific driver problem. You did not mention what you were doing when this incident happen. You have already did what is necessary to diagnose the problem by switching drives etc. Bar any comedy of errors, such as not inserting the cable properly etc., and no one meddling with the BIOS, then perhaps it may be a motherboard problem. Just switch off the computer and let it stand for a while to cool..this might cure the problem. Have you tried another cable ? or plug the Primary cable with the Hard disk still connected ( Computer switched off, of course !) into the IDE 2 and boot from the secondary IDE ? If the BIOS is configured to try to boot from all devices it will boot if the IDE 2 is okay. Is the power supply plug in good contact with the CDROM socket ? Otherwise, I recommend you check everything again before sending the mainboard back to the manufacturer for warranty. Some mainboard will work again when you send it back if you only have a temporary system glitch. It is quite rare to find the secondary IDE failing, although Mr.Murphy can appear under certain circumstances..

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

The cmos battery shouldn't stop the computer from booting, it'll just boot with default settings each time. If you have a totally dead box check the power supply first. You should always at least get a fan whirring or something.

first check your motherboard if it's able to take a 3.0GHz CPU. Further, check which socket is on the mobo. There are 2 different sockets - one is a socket 478 (for the P4 family 5x0) and a socket 775 (for the P4 family 6x0).\nI suppose you have a mobo with a 478 socket (due to the 2.40GHz CPU).

Is that your bios? Normally it's Del to get into your bios, but I've seen F2. Anyway, the worst thing that could happened in that you overclock your cpu or ram or video card so much they burn themselves out. That's the worst. Basically if you don't know what it is, don't mess with it. Or at least find out what it is before you do. If you do mess something up you can always restore the defaults.

Could be a number of things, such as:\n\n1) The power supply could be going out\n\n2) Computer may just be overheating\n    * Clean off all the vent holes & circulation fans on the PC tower\n\n3) Could be a short in the outlet, or cable\n\n4) Virus activity\n\n5) Hardware devices may be incompatible\n\n6) Motherboard is going bad\n\n\nIf it shuts off shortly after you turn it on, then it is most likely hardware-related.\n\nBut, if it shutdowns only after you have been on it for awhile, it is most likely overheating or virus-related.\n\nGood luck!

You mean everything? BIOS just woldn't come up? There is no way to fix that unless you send it in to the maker of the BIOS or where you bought your ocmptuer so they can fiz it.

Did you by any chance overclock your processor? Any way you will have to reset your bios to defaults. \nSwitch off your computer and remove the cmos battery. Look for a jumper which is labelled "Clear cmos". You need to set the jumper accordingly(to clear). Do not forget to replace the jumper to its previous setting. If you don't find a jumper, just short the two battery contacts with a flat screw driver. Replace the cmos battery and switch on your system.\n\nIf that didn't work, try disconnecting all drives and cards except the display and switching on.

set to 115watt? u mean volt? .. dont mess with that switch lol ... anyway ... make sure its the correct psu for the board 24 pin or watever ... if you have a dedicated graphics card make sure power is plugged in to that if it requires it .. and also make sure there is no other "floppy" or another type connector from the psu that needs to be plugged into some spot on the board... backtrack and take everything off the board but the videocard/proc/and mem ... see if it will boot to bios settup (del or f1) ... load bios defaults if it does .. then go from there ...

my dear friend\nyour mb model must be written between PCI slats or when u turn on your computer at boot screen it must write the model just press pausebreak button and write down model and check for it be carefull with bios update if u do it in wrong way you have to put your mb in trash.

I have this problem when working on motherboards a lot.  Usually, when you first turn the computer on and it's posting, sometimes it will give you a long string of numbers/chars that can help with mobo identification.  If you write this down, then it can help you to identify it.  Also, check your BIOS - a lot of times that will have info that's helpful.  You can do a google search for motherboard identification, and there are some good sites to help with that - one by computercraft, if I recall, has helped me in the past.

Reset the cmos. Check the CPU temp. Try a pci video card if you have been trying agp. Other than that I would say test another mobo and cpu.

Depends on your BIOS Manufacturer - Most modern motherboards use "delete". or if you have a HP or Dell it is usually "F1", or "F2"

If you have slotted in the ram correctly then it shouldn't be a problem. Just pull it out and start over again.\n\nBut all that beeping noise properly indicate you may have stuck it back in the wrong slot or the wrong way round. \n\nRam slots need to be read sequentially from top down. Example the first slot facing the CPU is the slot you must fill first. This order may be different in different motherboards though! Check your motherboard manual.\n\nAlso check you have not placed the module facing the wrong way! Ram don't need time to register with a computer, it is checked & acknowledged  immediately on bootup by the pc BIOS.\n\nIt's a good idea to test all your new ram modules before you use them. Check 1 stick at a time. Use Memtest-86. A bad ram module can really screwed up your pc.

Here is the driver download page for your MoBo\n\nhttp://support.asus.com/download/download.aspx?SLanguage=en-us&model=P4P800S%20SE\n\nPick your driver, If you still have problems after you have installed the card driver then it might be a jumper setting problem on the Mobo, Because it seems to be a problem with quite a few Asus MoBo's.

It's probably the cpu temperature alarm.\nDepending on your board, there is a temperature alarm built into the cmos.  If it is alarming, maybe your cpu is getting too hot.\nCheck your fan and make sure it's working well.  You may want to replace it with a bigger fan to keep it more cool
