Question about ASUS MB M3A78-EMH HDMI RT Motherboard

1 Answer

One long beep at boot up

I just purchased most of a new computer, but when I turn it on, I get one long, never ending, beep. My configuration is: 450w power supply, Asus M3A78-EM motherboard, AMD Athalon 64 X2 6000 3.1 Ghz processor, G Skill PC2-6400 4 Gig DDR2 Ram (x2) and a GeForce 9600 graphics card. I've removed and reinstalled the ram, which was the only solution I could find, but that did not help.

Any assistance would be much appriciated;

    Try removing the graphics card and turn your computer on. Post the result if it is still beeping.

Hogshead, a few suggestions here, but would like some more info too; does the beep start as soon as you hit the power button, or does the computer boot up even though it's still beeping?
Is the beep one long continuous tone, or does it pitch up and down like a siren?
This could be a couple of scenarios; one is the RAM, which I'm not too sure it is, the other is the CPU which is more likely.
Now, with the memory, this mobo uses dual channel memory, which means 'both' sticks have to be identical and both have to be working and have to be in their paired slots. Make sure you memory is good (have it tested or test it yourself), make sure the memory is seated (in) properly and the contacts are clean, and make sure the memory is in its pair slot which I can't remember if it's slot1 and slot2 or slot1 and slot3 (try it).
Now, more likely it's the CPU (processor), make sure the processor is seated properly and no pins are bent or tarnished (oxidised). If the CPU is damaged there is no way to test that other than putting it in another machine or putting another CPU in yours - be aware that what ever damaged your CPU is at risk of damaging another you put in there.
I've got to cut this short, we'll tackle more as you get back to me.
Let me know what happens.

Got a backup?

If not, download a Linux Live CD. Boot your machine with it, save all your data to an external drive and then do a complete disk format and re-install. That will be quicker in the long run.

Not sure about that PC, but on Dell, for example, you hit CTRL-F10 (I think) at power-on and it gives you the option of reinstalling the OS from the recovery partition (wiping any unbacked-up data in the process).,,Gateway is probably similar.

The Boot/BCD issue means your 'Boot Configuration Data' is hosed.

New build pc no boot... black screen

Try to remove the battery from the MB, and next time you try to install WIN XP, when you are asked how to format your drive, chose quick NTFS formatting; disable floppy drive in BIOS, because it might try to boot from it (and I suppose you don't have one), and in boot sequence (BOOT DEVICE PRIORITY) set cd-dvd as first, and HDD as second, and turn off any other device as bootable

My computer allways restarts after a blue screen in windows. what can be the problem ?

This is what we refer to as a blue screen of death. This generally means Windows is damaged or has bad configuration.

If you recently changed something in Windows such as installing a new hardware device please disconnect and reboot.

If you installed new software you will want to put your computer in to safe-mode to uninstall it.
  1. Turn off your computer
  2. Turn the computer back on
  3. After the beep, continuously press and release F8 on your keyboard every 1 second
  4. You will be prompted with a list of boo-up options. The options vary depending on which OS you are running.
  5. Choose SAFE MODE
  6. Once your computer boots up, click Start, then settings, then control panels
  7. Open Add/Remove programs and uninstall anything you installed before the issue occured
If this issue just happened without any changes try these steps
  1. Turn off your computer
  2. Turn the computer back on
  3. After the beep, continuously press and release F8 on your keyboard every 1 second
  4. You will be prompted with a list of boo-up options. The options vary depending on which OS you are running.
  5. Choose Last Known Good Configuration
  6. Windows will attempt to do a simple restore of its configuration files
If all of the above fail your best option is to talk to a PC technician in your area.

Computer wont boot hear one beep from motherboard over and over

If your power supply is bad, there is typically a much cheaper way to fix it rather than purchasing a new one.

If you know a little about electronics or know someone who does have them open up the power supply and check the capacitors. Often times when a power supply goes bad its the result of capacitors going bad.

If you notice on the ends of any capacitors a brownish/whitish discharge or "bulging" then the capacitor has gone bad.

A new one typically cost less than a dollar and replacing it is fairly easy if you know how to solder.

Let me know if you have anymore questions and hopefully if this is the case you can save some money.

From 300w psu i change it to 450w will that be ok?

Ivy My field is in home appliances. I do fix my own computers and have replaced a few power supplys. The only thing I could say to you is go back and recheck your connections. They should only fit on the bord one way. The other connections for the hard drive and cd drives and so on really dont matter. so good luck and I think if you recheck it all the computer will work.
