How can u tell your motherborad is bad


Disconnect the power cord form the power supply, be sure the power supply is set for 110 or 220 volts depending on your location and power and double check it (most have a 110/220 switch) Feel/look at the back of the power supply to determine if the fan is working. http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm If the fan is working, try another power supply anyway. Plug the computer directly into a known-good (a lamp works) power outlet Check to be sure you do not have a motherboard stand-off in the wrong position and shorting-out the bottom of the motherboard. Inspect/shake and listen for loose metallic objects (loose screws) on top of and under the motherboard and in expansion board slots. Look carefully at the ISA and PCI slots, see if any of the contacts got bent/shorted-out. Sometimes an expansion board will dislodge one and it will be pushed into the bottom of the slot. Inspect the motherboard for broken or burnt components. Carefully inspect the motherboard for black soot from bad bearings and clean and replace the culprit. Look for bent/shorted pins on the motherboard headers and straighten. Be sure the speaker is plugged into the motherboard. If you hear beeps. Decode the beep code. If not, double-check all jumpers. Push down on all chips that have sockets in attempt to reseat them. What CPU are you using? Be sure the core voltage is correct. Be sure the CMOS battery jumper is in the correct position. Some distributors purposely ship motherboards with the jumper in the wrong position. Find the jumper that clears the CMOS, put it into the clear position for several minutes, put it back in the normal position, plug-in the power cord, and push the power-on button. If you apply power to the motherboard with the jumper in the clear position you may damage the motherboard. Pull all boards except video. Disconnect all cables going to all drives, pull all cables except power, power on, and speaker, connect the power supply to the motherboard (the black wires go in the middle on AT power supply connectors--"Black OK, red your dead"), reseat the memory, plug-in and screw-down the display adapter and nothing else (push down on the top, front of the adapter and make sure it is properly seated by looking at it all along the PCI or AGP connector), connect the power-on switch and the speaker. Check the monitor plug for bent or pushed-in pins, connect the monitor and nothing else. Check the monitor power cable. Reseat/replace the memory. Check for Motherboard Electrolytic Capacitor Failures Check the CPU for bent pins. Try another processor. Note: If you apply power to a motherboard with an Athlon or Duron processor without the CPU fan connected, even for a few seconds, you will fry it (see http://duxcw.com/digest/guides/cpu/socketa/heattip.html). Check the CMOS battery with a multi-meter. Should be around 3 volts (2.8 is ok). Try a different video board. See if the CPU and memory will work with another motherboard. Pull the motherboard, set it on the box it came in, install video, memory, CPU, power, and power on. See if it boots. I have seen several instances where this works when the board will not work in the case. And, when reinstalled in the case, it continues to work. I have also seen where it didn't work out of the case immediately, but did work the next day and continued to work. One of those mysteries. Temperamental computers with minds of there own. Replace the motherboard.

Does not boot


To exclude a possible short, remove the MB from the case and place MB on to a couple phone books thats covered with a non static MB bag. Connect power supply, keyboard, mouse, primary hard disk drive, monitor and internal speaker. Also leaving CPU/heatsink assembly and memory connected.
Short the power-on pins by using a pen. See page
1-34 in you're manual, PWR BTN. If the system boots ok than there was a short with the MB while in the case. If the system does not boot than the MB is bad or the bios needs flashed. Keep the MB out of the case and follow the instructions on page 2-2 section 2.1.1

I had a loud fan noise coming from inside my desktop box for a while. One day (& ever since,) when I went to turn the box on, absolutely nothing happened: no fans, no BIOS, no LEDs. I made no config...


This may work however i think by ignoring the sound of the Fan you might have destroyed the cpu and the motherboard.If you can try the processor in another machine you might just have to replace the motherboard only.
Good Luck

Dell PC won't start


No beeps are heard, no CPU fan is turning on, only blinking yellow light. This brand usually experiences this problem.
  1. First, check the power supply. Disconnect connectors from the board and make a jumper wire for the green wire to any black wire. If the PS fan does not spin then it's busted, else proceed below.
  2. Reconnect connectors except the one with 4 wires, 2 yellow and 2 black, then switch on. If CPU fan turns on then you have a bad processor.
  3. If the fan is still not turning on then check the USB port pins for short circuit.. disconnect it from the board and switch on.
  4. Do the same with other hardware connected to the board.
PS: The metallic casing of computers must be connected to the common ground of the power utility to protect it from stray currents that result to damage of sensitive components such as processors, memory and hard disks.

Power supply Ok.But CPU fans started with seconds It's stop.


sounds to me like your mainboard is bad, i bet if you closely inspect the capacitors around the cpu one or more is bulged out or leaking

Wont post and buzzing noise


Don't mean to butt in here but I'll bet the 4 pin_ATX 12v connector is not connected to the board. That 4 pin_ATX 12v connector give's the CPU it's power. Without is the system will not boot. Some boards will give off that weird sound you are hearing.
