can anyone help. when i turn on my computer the power suooly turns on then shuts down straight away is it a faulty power supply or could it be something else. your comments are appreciated

Is it exactly 1 second, or less than 1 minute? Did you get a series of "bleeps" from the PC as it is starting up and if so, please describe the 'bleeps' e.g. 2 short, rapid bleeps followed by a single long bleeb. Can you power up your PC at all?

Sounds like psu could be the place to start

Any thunderstorms lately? Do you have surge protection?

Think you had better get another power supply!

You could always "borrow" on from one of your other machines.

One other thing, try removing the processor and memory then see if it powers up with a series of beeps.

Could be the case switch - happened to me some months ago: "...PC powers off a few seconds after powering on..." click here. G

If you don't have an alternative switch to try, do what woodchip advised in the above link: "As above if it's a ATX a screwdriver across the two pins will start the computer. it is only a push to go switch. push and it shorts the two pins to make a connection then when you remove you finger from the button it will keep going as it is controlled by MOBO and Operating System".
