possibly a bad psu.(if possible try another working one)

youll have to go through everything to check whats faulty because
it could be a number of things that could cause them things.

check the bios settings
check ram
check all the connected componets that the psu is connected if any are faulty.
check to see the motherboard is connected properly on the front panel so to
see if they are working ok
check the power options on the operating system.

I had same problem you have a problem with your power supply

I had a problem like this. Mine was the chipset over heating on the motherboard, pointing another fan at it solved it.

Does it even show the BIOS on the failed attempt to boot. If not it is definitely a hardware problem.

every thing is in correct its screwed in tite

Can you leave it off overnight. and then after your first power on, cycle the power every 15 minutes and note how long it lasts until it won't reboot.

Have you updated to the latest bios?

Which of your fans are blowing out, and which ones are blowing in?

ye i turn it off every night but when i turn it off it takes about 50 55mins to turn on i have to take the power lead off for it to work again i have tried many times after i have turned it off and it will not work unless its been disconected from the wall and left for the time stated

Even if your psu is new try to replace it.
The psu has 5 different output voltages.
The fans need 12v to operate. If the rest outputs are not good, the pc will not start but the fan and the power led will operate.

If you don't have a spare psu try this:

Remove all the power connectors from your fan, your optical drives. Also remove the data cables from your drives.
Leave only the 2 power connectors on your motherboard, the power of your hard drive and if exists, the power connector to your vga card.
Then, try to start your pc.
