Question about Intel Motherboard

1 Answer

BOOT PROBLEM After I disconnect my PC from the power outlet, unplug the power connector or turn-off the AVR for a few minutes, whenever I switch on my PC again it won't boot.The PC turns on but nothing appears on the monitor. I tried refreshing every single connection on the motherboard but to no avail. I even removed the memory RAM and I didn't even hear no beep codes. But in the end I was able to properly boot my PC only after I exposed it to electric current by leaving the AVR turned on for at least an hour. I also noticed that when I was able to boot my PC that the clock is stuck at the last moment the PC still has power. I think the problem is whithin the motherboard itself because I don't have any adapter cards attached on the motherboard slots. But I still would like to hear any opinion anyone might have on this dillema. THANK YOU!!!

    I also tried using my old 230W PSU that I tested on this motherboard and worked fine just a few months ago, but it still didn't solve the problem.

How to fix a motherboard that does not turn on at all.


Make sure there is power at the outlet, surge suppressor, power strip. Be sure any connected UPS is on. Try again.

Remove any recently installed hardware and go for boot. If the PC boots, check to make sure that the new hardware does not overload the old power supply - if it does, replace with a higher capacity power supply and go for boot.

Open the PC. Look for indication of power - LEDs, fan, etc. Replace the power cord between the outlet and computer if one is available, and go for boot.

If possible, obtain a power supply tester to determine if the power supply has failed. Replace any failed Power Supply and go for boot.

Disconnect power. Disconnect all non-required cables and accessories. Leave only the power and data cables for power supply, boot drive, video card, mouse, memory and keyboard connected - everything else should be removed (with the exception of the small cables that go to the MoBo headers for LEDs, and switches on the case). Everything means both data and power cables. All controller cards should be removed as well unless using on-board or built-in controllers. Reconnect power and try for Boot.

Add devices, cables, etc one at a time to determine which is causing the fault. A PC that boots and shuts down shortly after could be an indication of overheating / over load. Clean dirt & dust from case, ventilation slots, etc. Make sure all fans spin freely - replace any that do not.

Those are some things to start working on.. hopefully, you'll find the problem and not have to go further. Good luck!

There is a green light that comes on and now my computer will not turn on. what do i do?


hello tchief hi, I will give you the three computer parts that you need to check and may sure they are installed and tested properly before powering the computer.
  1. The power Supply, to check this part, you need to know if the fan is blowing. no blowing fan no power. You should have connected this on power outlet or AVR, on motherboard 20/24 pin and 4pin 12 volt connector, (you can test this by unplugging the 20/24 connector then short the green and black wire)
  2. Memory. you should clean the gold terminal, use a pencil erase to clean the gold contact. As you install you should hear a snap sound or just make sure they are connected properly.
  3. Video Card, make sure that this card is connected properly. SNUG AND FIT.
Now power it on Still No success? Do the above several times. Still? If you have Spare memory, try them, (are you sure the memory is good?)

The red light is just a pilot light indicating that it is still
connected to the power line. To get it totally off, is to
unplug the unit from the outlet. If your PC is connected
to the AVR (Automatic Voltage Regulator), just turn the
power switch off at the AVR. Hope this help you.

When I attempt to turn on my computer after playing with the switch front and back it will start sometimes and run for a few minutes and then shut down. When I remove the four pin connector to the mother...


I've seen this before but the 4 pin connector was burnt pretty bad and not making a good connection. I'd see if you could gently scrape the pins a little bit with a small knife(motherboard) See if the connector from the power supply looks ok and doesn't look like it's gotten hot. The holes in the center of the 4 wire connector can be a little bit larger than the pins themselves also. You might try plugging in the connector and then holding some side pressure on the connector while you try to start the computer. Also unplug the hard drive and cdrom while you try booting. The power supply may not be putting out enough amperage and unplugging drives may give it a little more power. That would mean you might need another power supply if it works.

Don't know the cause of the problem with my pc.


Check your memory module. Unit turn off and unplugged to the outlet. Reseat or clean its edge connector with soft eraser.

Or try to reseat it to next bank(same specification). Or try to use another good ram module.

Computer does not boot up.


First of all, power down, remove all cables and check to see if your Graphics card is inserted correctly. Also try removing and re-seating the graphics card.

Check the cable from graphics card to monitor. Also try cable and monitor on another pc to eliminate this possible cause.

Failing that, you could have a BIOS problem.....did you recently try to flash your BIOS chip??

Won't boot up


We cannot assume that your motherboard is dead, try these: Unplug computer power cable from the socket outlet.


First, check to be sure the power supply is switched to 120 V.
If it is, then do a minimum system configuration test. Turn off the ON/OFF switch on the PS back panel, and disconnect the cord. You don't want to work on the motherboard (MB) with standby power applied.
Disconnect all components from the motherboard (including floppy, CD, hard drive). Leave the power connector attached to the hard drive, as the power supply has a minimum load requirement (never run a switching supply without a load, unless it is designed to do so -- and few are). Remove the power connector from the Motherboard, then reinsert it (potential for bad contact in control circuit).
Remove the RAM, reinsert one stick (going for a minimal configuration).
Remove all PCI boards and AGP. The motherboard should be able to turn on and beep an error code even without RAM and video.
Plug the PS back in, turn on the back panel switch, and use your screwdriver to short the power button pins (ATX type of supply).
Double check which pins are the power switch pins in the documentation, as front panel attachment point functions are usually not obvious, and are easily mis-wired since the connectors come off so easily during maintenance.
When you touch the pins, the CPU fan should instantly start turning, and shortly thereafter, the MB should beep an error code.
If not, check the mounting for the MB. Some cases use a U shaped rectangular snap in receptacle for MB mounting screws. These commonly become bent or twisted, and can short out nearby traces sometimes resulting in dead board symptoms.
If the fan didn't start turning when expected, you probably want to repeat this minimum configuration test with the motherboard out of the box.
Put it on an insulated surface (e.g. pink packing foam or cardboard), being careful about electrostatic discharge (ESD) (however, my bet is ESD damage that disables a motherboard is rare).
Although I haven't seen it, your motherboard may require the video card to be plugged in to turn on.
I doubt this, though, as there is enough housekeeping to do before checking for the video card that the fan should have time to start to spin.
If it still isn't working, try the other memory stick, or remove all memory.
Double check all connections before applying power!

The repeating single beep with a small pause (actually 3 Beeps a Pause) clearly indicates problems with RAM .Replace it ,your problem will be solved . As for connecting the 12 volt 4 pin connector all mobos are designed to sense the presence of this 12 volts and ONLY THEN TURN ON.

BIOSTAR K8M800 Micro AM2 wont boot


It's suppose to do that. These motherboards are new generation. After everything is ready to go, you plug the power cord to the wall and pc. The computer power supply fan spins for about 3 seconds or so and maybe a few lights blink. This is normal. Its kind of a self diagnostic telling itself (I'm ok, you can power me on now). Did I answer your guestion? If not, let me know.
