Question about MSI K8N Neo4-F Motherboard

3 Answers

Starting computer When I press start button from shutdown mode, it wouldn't start right away. I disconnect power cable, toggle the switch between ON/OFF, while pressing start button. After several such attempts, it starts, but produces two loud and long beeps with constant sound in the background. My friend told me to shut it down right away.

    Thank you very much for your reply.

    No, it doesn't show anything unusual. Just loading. But after it's loaded, it shows in the bottom bar that the network cable (cat 5) is disconnected, while the cable was connected and I was able to go on-line. And the "background" sound (not very loud, but constant) is always on.

    Thanks,
    Andrey

    Hermit, 1st of all, thank you for your help.
    I tried other keyboard. Didn't work. Let me tell you how it works.
    First, the front button wouldn't start the computer. After several presses, it would start, but turn itself Off within 3-5 sec. After that the button freezes again, and you had to hit it several times before it starts the computer. Then sometimes it would turn Off again in about 5-10 sec, sometimes not. All this is accompanied with sound coming from monitor. Yesterday I found a small fan on the MB which seemed to be malfunctioning. It rotated unevenly and seemed to cause tripping of computer. I took it off and cleaned. Now it's working OK and the computer doesn't trip. But the buzzing sound's still there. It's steady, but becomes louder for 3-5 sec at every step of booting. First, when computer starts identifying its hardware, then it gives a even louder sound when it starts loading Windows, and the most loud sound when it opens Windows (displays Window welcome screen). Between these three steps it clicks (like in a bad phone communication) and blackens the screen for about 1 sec. After that it works OK (at one point when I started it, the screen was greenish). After the computer is shut down, the monitor gives one more louder sound and then goes to standby. Oh yes, and I found three files in quarantine, infected by Trojan Horse.
    I think I gave you the whole picture. Thanks again for the help.

    Hermit, I don't know if you received my comment, because I hit the "Fix it" button and everything disappeared. I thank you very much for your help. Your help really helped. I replaced the monitor and now it works fine. I also checked the old monitor on another computer and it did the same things. So the problem is the bad monitor.
    Thank you again.

Good for you, Adrey! Am glad you found the goblin finally. See you around, okay.

Your power and data system need inspection inside the MoBo. Hardware problems produce warning beeps, especially RAM and VIDEO. Check these first to make sure they are in slots.

Does it show anything on the screen while it's beeping??????

Please provide more information and come back

    Let's start with your keyboard. If windows is running and a constant sound persists, it could vey well be a stuck key on yoour keyborad. Try a different keyboad or unplug the keyboard after the computer boots.



    The network diconnect sign can be ignoored if you can get online, but if you can't, try replacing your network cable terminating clip--the one that goes into the network card. Also check the other end coming out of the switch or wall socket.



    Let us know, okay

    Hey, Adrey,



    Your computer sounds like a Harry Potter scene! (Kidding :) I want to say that that thing has more than one problem. It is one of those where I would disconnect things one by one and reconect backward to isolate the problems. Let's try this,ok



    1. Once it's booted and wailing, turn off the monitor that you say wails loudly. Does the sound stop?



    2. Remove the sound card and speakers, then restart the computer. Any sounds?.

    3. Disconnect the HDD and CD Drive and turn the PC on, let the fan run for a minute. Any sounds?

    4. If you have a different monitor, try it and see the diffrence.

    5. Remove the cooling fan from the processor and turn PC on for only 30 seconds. Any sounds? Don't keep it on without the fan too long thou.



    This process of unplaugging parts you are suspecting are faulty will give you a basic idea of where the sounds are coming from,



    Your MoBo may be having a problem, like getting ready to die, or has a short somewhere.



    Your power supply is also suspect, and could cause variable power relay and cause Harry Potter type events.



    Let's keep drilling down, okay.

1. There is a BIOS SETUP setting to "automatically start after a power outage" -- this is useful for "servers".

2. If you press and HOLD the power-button for TEN seconds, the computer should shut itself off.

3. Turn the computer off, disconnect the "data" cable to the HDD (hard-disk-drive) and then turn the computer on. Does the HDD lamp still light-up?

4. Do you get any on-screen video when it starts to start-up?

See if you can enter SAFE MODE. After turning on the power watch the screen and when you first see Starting Windows press the F8 key several times until you see a menu, select Save Mode. If the computer boots to save mode, it's probably just a driver problem.

Computer power ON/OFF behavior is not as expected!


Hi...

If all the parts of your computers are fined functioning. This is a CPU problem witch is no display. Try to disassemble the CPU remove the heat sink the CPU and clean and insert it again. When you are now inserting the CPU be sure that you will put a thermal past in the heat sink so that the heat from the CPU are absorbed. If the heat will not be absorbed it will cause overheating.


Good luck! Thanks for using fixya.

Power Problem


This is an issue with the power management and sleep setting of your machine. Basically when you press the power button and the machine is in sleep mode the machine will resume and then shutdown. Then if you press the power button again it won't work until you hard reset the machine by pressing and holding the power button for at least 10 seconds.

Follow this link for info on setting an s3 sleep state in xp.
Also check your settings by going over the information on this page.

For Vista the S3 sleep state is on by default and you might want to change this. To do this follow these instructions.

Issue: No power or computer does not turn on.
Cause: No power from the computer can be caused by any of the below possibilities.
  1. Connections not connected properly.
  2. Third-party hardware.
  3. Bad power cable.
  4. Incorrect power supply.
  5. Bad battery.
  6. Bad power supply, power button, and/or power board or inverter.
Solution: Note: If the computer is turning on but is not (beeping) or giving any type of picture on the display. If you are uncertain if the computer is turning on or not, this can be easily checked by locating any fans in the computer or visible from the outside of the computer. If these fans are spinning, the computer is receiving power and this document may not apply to your issue. Connections not connected properly Verify that the power connection is connected properly to the wall and the back of the computer. If the connections appear to be connected properly, attempt to disconnect and reconnection both ends of the cable. If you have a power strip (surge protector) or switch used to turn everything on at once, temporarily disconnect the computer from that switch and connect that cable directly to the wall. This will help verify that the strip or switch is not bad. Verify that the outlet works by connecting a different component to that switch. Third-party hardware : (If )additional hardware has been recently added to the computer it is recommend that you temporarily disconnect that device or devices from the computer to verify they are not preventing your computer from turning on. Bad Power cable : Verify that the cable supplying your computer is not bad or damaged by using another power cable. If you have a standard crt modem this cable can be used in place of the computer power cable. If you have a portable computer or laptop, when the cables are plugged into the laptop you should see a power light or battery charge light. If this light is seen, this is a good indication that the power cable is good. Incorrect power supply If you are building your own computer or if the computer has never turned on since you purchased it, it is possible you are using a power supply that does not supply enough power and/or the incorrect type of power supply. Verify your power supply meets the requirements of your motherboard and processor. Bad battery If your computer is a laptop or portable computer that utilizes a battery for mobility it is possible that the battery may be causing your issue.
  • If your computer powers on when the cable is connected to the portable computer but not when it is disconnected, we recommend you purchase a new battery.
  • If your computer does not power on when the battery is connected and when the power cable / charger cable is connected, try removing the battery and seeing if the computer can power on with only the power cable connected. If no power is still received, skip to the final section.
Bad Power Supply, power button, and/or power board or inverter If, after following the above sections, your computer still receives no power, it is likely that a hardware component in the computer has failed. It is most likely that the power supply has failed. If you do not plan on replacing the power supply yourself or if you have a portable computer, we recommend having the computer serviced by your computer manufacturer or a local computer repair shop. If you have a desktop computer and plan on trying to repair the computer yourself, we recommend you replace the components in your computer in the below order.
  1. First open the computer and verify the power connections. You may also wish to consider disconnecting the main power cable and reconnecting the power cable to make sure it has not become loose. Also verify the power button cable is correctly connected to the Motherboard.
  2. Replace the power supply with a new power supply.
  3. Replace the motherboard.
Hope this helps ya/Please dont for get to Vote.Thank You

Try a few things for me OK? From what you typed, turned on the psu "the toggle switch on the psu", pc seemed to be starting up. I need you to keep the toggle switch on the power supply in the on position. Press and hold the start button on the PC case to shut it down. Give it a few seconds & power up by pressing the power switch on the case. Notice a differance? Next, unplug everything connected to the pc expect the monitor, mouse & keyboard. Try to boot. Still no? Remove the side of the case exposing the board. Turn the psu off by flipping the toggle switch on the psu, wait till the green light on the board goes out. Grab the Mb ( I know it's tight in there) and see if you can move the board in any direction. Not loose? Re-check all data & power connections for a solid connect. Re-check your case to Mb connections. Also check the PSU, there is a red slide switch it should be set to 115v. Post your findings..
