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

My pc is shutting down and I can't wake it up without shutting down the power from power supply. The Antec 300 tower has two blue lights- the top light starts blinking when it has shut down and I


sounds like a power supply problem

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive



Test all leads that attach to your hard drive power and data cables IDE SATA
the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

hope this helps

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.

Fan makes loud noise after computer warms up. I do not want to purchase a new power supply. Can and where can I purchase a new fan and can I easily inststall it?


If you open the case, it is doubtful you can touch the fan blade. They mostly are at the back of the case within the silver power supply. If you can touch the blades, it is most likely a case fan you have a problem with. They cost about $10.
If it IS the power supply, you can get one for about $35. I don't know where you live, but any computer store should be able to sell you a new case fan or power supply fan.
One thing you need to be sure of, though, is if it matches what Gateway has installed. They are known for installing hardware made especially for them and generic hardware may not fit in their case.
In that case, Google is your friend--type in the part that you need and your computer model and you'll find what you need.
If you go to a computer store, take the defective part in with you to match it.

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.

No boot, New PS, Green light on MB lights, No Fans running


Bottom line: Either your power supply or (hopefully not) the mother board has gone bad.
Replace power supply (remove old one), take to local independent computer shop, ask them for new unit. Should be around $50.00. - no more. After reinstall, if still no fans, boot, etc. Replace motherboard or buy a new machine. MB's installed probably will run you around $250.00-ish.
Good luck.

E machine wont start


Here's something you can try: If you can borrow a computer power supply rated at 350 Watts or more from someone, do the following: Unplug your power supply from the motherboard. If it's an older model (pre-Pentium 4), there will be one wide (20-pin) white plastic connector. Along one of the long sides of the connector, there's a retaining latch. Squeeze it, and gently rock the connector from side to side along its length, while pulling up. The connector should come free. If it's a newer PC, there will be a second connector with 4 pins, and yellow and black wires. If so, squeeze its latch and just pull up on it. Next, disconnect the white power connectors from the optical drives, hard drive, and floppy drive. If the internal fan you talk about is a case fan, unplug it, too. At this point, you should be able to take all of the power cables and hold them out of the case.

Now, plug the power cables from the power supply you borrowed into all of the sockets you just vacated. The motherboard connection(s) have a little nub on one side; this lines up with the latch on the plug(s). The hard drive and optical drive connectors only fit one way. The floppy connection is wider on one long edge; this sits on a little shelf when the connector is plugged in. Plug in the case fan. Make sure the borrowed unit is not resting inside the case. Finally, plug the AC power cord into the socket on the borrowed power supply. You should now be ready to push the PC's power button. Do so.

If the PC boots fine, you have a bad/failing power supply installed in it. Sometimes they just don't have enough power to boot the motherboard when other accessories are also drawing power. If more accessories than those which came with the PC were added, this makes the problem worse.

If this works, you need to replace the original power supply. With your PC turned off and unplugged, remove the 4 screws holding the power supply to the back of the case. Lift the unit out. If you can keep the borrowed one, it's simple. Place it into your casr where you removed the original one (note the unit will fit two ways, but the screw holes only line up with one of them), line up the screw holes, and install/tighten the screws. Plug in the AC cord, and boot the PC up. If everything is okay, turn it off.

Since you're already inside the case, take some canned are and dust off the internals. Be especially sure to remove any dust between the processor's heat sink fins. Hold the processor fan with a finger to keep it from spinning.

Of course, if you CAN'T keep the borrowed unit, disconnect it as above, obtain a replacement, and repeat the installation/connection steps above.

Let me know if this works.

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.
