Chances are you need to change the power supply,, but first you need to check to see if its workingm this is quite easy

1.) unplug it
2.) remove the power connector from the main board
3.) on the power connector is a green wire(ONLY ONE) and right next to it is a blact wire(any black will work)
4.) use a peper clip or unisulated wire to bridge the green and black wire by inserting it into the jack contacts.
5.) plug in the power supply, if the fans spins then its working..

If the power supply is fine then you will need to check the power button connectors *wire from power button that connects to the main board),, if the connection is fine, then unjack the connectors and use a bladed screwdriver to bridge the pins for the power button connector on the main board,it should boot up. If not then you need to have that mainboard replaced

Have a new Urban S71 case with Super X5DP8-G2, checked it by connecting blk and green wire on 24pin ATX power connector on the Corsair TX650 v 2.2 cpu fans and case fans all operate. Blue high low fan...


It booted up once, and now fails?

Quite likely it is defective. If it booted once, it should boot again.

Make sure the little SQUARE 4-wire plug from the power supply is also plugged into the Mobo. Commonly overlooked, and can drive you nuts trying to figure out.

Best 'o luck, Barry.

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!

The cooling fan for the interior of the cpu case froze up and now the computer will not boot up. I replaced the fan but the computer will still not boot. I can see the lights on the front of the unit come...


It's the power supply, the cd drive door will open in all cases if it has power - 12 volts to be more precise. Simple test: take the cd unit and the power supply out of the case of the pc, connect them  and start the PSU (connect the green wire to a black one) - if the door opens now it means that there's a big short on the motherboard, if not the PSU is fried.

Asus mb wl300 amd 64 4000+ won't boot to bios.


To make sure it isn't anything else, pull all cards, and drive cables from the board so the only thing left connected is the power connectors to the motherboard, the speaker, and the power button. Pull all the ram cards.

Now power up the computer. If you hear a series of beeps then the computer recognizes there is no ram on the board. At this point I would take the power supply out and have it tested. If you do not hear a series of beeps I would still have the power supply tested as it could be the 12v is fine but the 5 and 3.3 volt side is bad.

If power supply tests good then I would replace both the motherboard and processor. You take a risk of burning a new processor if it's the motherboard causing the problems.

Computer does not boot


If you computer over heated, this could have caused the board or power supply to short. I would first start by trying a new power supply unit (since this is cheapest of the options). If that does not work then try replacing the motherboard and/or processor. Since you not getting any power, my guess is motherboard or power supply unit.

Installed new mother board, bad things happened.


Hi,
Assuming that you triple checked to make sure you made all the connections right ( and that the motherboard diagram is not actually printed upside down giving you a backward christmas tree line up for the pronged connections (which happens)... and that you did apply the heat sink insulater goop nice and perfect...and that all your stuff is compatible with each other..
there are two possibilities.
Either you got a bad motherboard or you got a bad power supply.

Good quality power supplies are equally as important as the mobo.
Swap out the power supply. If the problem repeats, its definately the motherboard.

Thankyou and good luck. Please remember to rate my answer *s*

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

Elitegroup 848P-A7 Motherboard - Will not boot


I had this exact problem with a newly bought motherboard and it turned on fan turned but the screen was black, also I noticed once it turned on it wouldn't turn off, (Am wondering if this is the case with you) the motherboard was fine as it is in the other room now working away, so dont get rid of yours just yet. Most new motherboards require additional power to the processor from the power supply, through a four pin power cable, which should be availble with the newer power supply units having (number of pins for you motherbpard power supply) + 4 (which is the 4 pin J-connector) printed on the packaging. If this is connected and you are still having problems which for me was the case, then you will have to try a different approach. Cutting to the chase, the problem I had that produced similar effects of screen being black when the motherboard was powered on, was to do with my case. It was one of those flimsy aluminium foil types. I came to this conclusion by taking my motherboard out of the case and hooking it up to the cases power supply on an insulated surface such as a cork mat. It then was working fine. So I bought a good qulaity case with a new power supply just to be sure, hooked everything up and hey presto it was fixed. It turned out that enough power couldn't get to the board as the cheap case was shorting its supply. Hope this is of some help.
