The power light on could only mean the light on the psu is gettting power

Test your PSU 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 or to shutdown or fail to detect your hard drive boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they could be faulty ? one bad lead will end with a computer error a computer needs its connections continue its cycle and have an end to function properly

even something as small as an electrical extension or a faulty fan lead can cause this problem computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

make sure your computer ram modules are securely seated with no dust in sockets also Cmos battery has charge with no dust in the socketshope this helps

Check it for dust / dirt. Clean it or replace it.
Good luck,

Surge has possibly fried the PSU. Depending on the severity, you may find other components are damaged on the motherboard.
Best way is to test with a known good PSU

No,
Your PC is perfectly powered, no need to upgrade.....
the normal things that you generaly upgarde is RAM and Diskspace

why would you need to change the wattage but yes if you have the same connections the comp will only use what it needs 12 amp for the mother board 3 amp for the HDD etc changing it will allow you to add extra HDD or DVD or CD etc.

Sir here is the link where you can find how you can install your power supply http://compreviews.about.com/od/tutorials/ss/DIYPSU_2.htm

the original psu is dead toss it. the one you are using is not powerfull enough to run the pc. check the old opne for how many watts. then check the new one. i bet the new one has fewer. so to solve problem get a psu with the same or more watts than the old dead one.

Remove the PSU. If you have another one of equal (preferably larger) power output, then replace it and connect it like you normally would (sata connectors, aux 12v 4-pin, molex hdd connectors, etc...) and see if it works.

Its most likely that one of the 12v or 5v rails has burned out or that the entire unit itself is burned out. Either way, its done in. You'll need a new one.

that atx connector is faulty it becomes loose because of draw and insert the connector in mother board grips of connector can be tightned by pin the fault may lies in motherboards connector desolder it and replace it

It might be the motherboard. Take the computer to your local computer repair shop and have them test the power supply and the motherboard. I hope this helps!

For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!

check your power pack thanks.

indication of a failing power supply??? I dont think so.
more like a driver is corrupt or better yet have the on board nic card set to turn on, is there a plug that has wire attached to the nic card, unplug those and see what happens.

look for bad caps, bestec power supply's fail a lot
