Just because the power light is on on the board doesn't mean the power supply isn't faulty. Especially if the fans are not spinning. You can test it for sure with a psu tester like one of these:

Do you hear any fans? You may need to open the computer case and look inside to see if you have any led's or fan's functioning. If you do not see any lights on the mother board or working fans, check the fan inside the power supply by looking through the fan guard. If you do not see the power supply fan working, make sure you have the computer plugged into a live outlet, and the power cord is good. Furthermore, look for a switch on the back of the power supply to make sure it is switched to the on position. If you still have no working functions of the computer, go to a computer store like Comp USA or Best Buy and purchase a power supply tester which you may find for under ten bucks. Touch the metal case of the power supply while removing the main power connector of the mother board. Always touch the metal case of the supply to discharge any static, or you could cause immediate or future damage from weakened static sensitive components. Plug the power connector into the power supply tester and make sure all lights light up. If no lights light up, you can check the fuse on the supply if it is external, or you will have to open the power supply to check the fuse. Alternatively, you can buy a new power supply which you will need to do if some of the lights on the power supply checker light up.

If the fans work on the computer and the power led's work then you may have a bad video cable connection, video card, or monitor, which will need to be checked individually. If you hear any beeps, check your manual for the description of the number and duration of the beeps which will indicate bad video or memory sticks.

I hope this helps but you can reply if you have any other questions. I think it could be the power supply with all the storms this time of year which could have killed the Power Supply which is easily replaceable.

After power on no display on monitor & key bard not illuminated, only CPU fan running Please give solution Thanks,

If your working with an adapter video card better unplug the card and insert your monitor video cable to the onboard port on the VGA port. If that helps maybe your video card is defective or need cleaning or just loose on the slot.

Better also be sure that your PSU (Power Supply Unit) is good. It is not an indication when all your fan is moving and indicator lights are up that your PSU isn't defective. There were so many cases like this where most everyone jumps into conclusion that their motherboard is the problem and after replacing it with a new one they face the same problem. You should test your PSU to other working unit.

If your sure that your PSU is ok, better test you CMOS battery or replace it with a new one.

Hope this helps. Any vote is highly appreciated. Thanks :)

Won't boot. mobo power lite is on. fans power up for split second. have check everything. cpu is new. checked ram. all devices. No lose connections. reseated cpu twice.

It sounds like a problem with the power supply. Do you have another one you can test with? You could also purchase a power supply tester.

Here is a link to the power supply testers on Amazon. There are all sorts of prices and features so it really is a personal preference which one you get.

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!

First, Make sure you by the right motherboard screws to lift the board from the case or youll ground out and blow the power suply or the mainboard or both.

You can buy power supply testers at most computer stores for around 13 to 20 bucks and test the power supply.

The one i use for work tests the power supply and the board and shows the voltage output, it was $16.

If both test good, then try connecting everything first and then connect the power supply. Make sure the Pins for the reset and power swithc are connected correctly.

Do you know the processor to be good?

Also try reseating the RAM in the slots on the mainboard, check that the metal pins for the processor arent bent underneath.

Some boards have the wide connector and the small four pin connector and some only have just the wide one depending on the its power requirments. make sure both are connected if it requires both.

Make sure the BIOS battery isnt dead. its on the Mainboard and looks like a watch battery. Pop it off and stick your tongue on it and see if you taste a charge ( you know, like with the old 9v rectangle batteries when we where kids)

You may just have a bad board or not a power full enough power suply for that board. It could als be that.

I would reccomend you get a power supply tester. I have one that was $16 and has both the 20/24 pin and the 4 pin Mobo tester for the power supply and it will test the power supply and the it will test through the mother board to show if its getting a solid 12 volts of power. It also has a floppy and a sata and the 4 pin tester for the drives and Mobo and is worth the money. Heres the one i got at a local ma and pop store in San Antonio Texas. You should be able to buy similar at any tech store. good luck.
