Computer Turns on then shuts off in half a second

Jacob_58 · Mar 15, 2016

What is actually happening to my computer, when i start it up the LED light to my fan Turns on just for a split second immediately, i've unplugged my GPU to see if it were my PSU but I don't think it made a difference. Could some parts of the Computer be "Fried" ?

I cleaned the computer (before it was broken) taking all the PSU cords out and cleaned it out with a brush. I put it all back together then it didn't work... Could this be the PSU or motherboard?.

And another thing my friend accidentally Leaned on the mother board? not sure if that would've caused anything?.

Check to make sure all the cords are in the right place

Describe your friend leaning on the motherboard.

There are a few things that could have happened. My immediate impulse when I saw the title was that your power supply was failing you, but after reading your description I'm pretty sure your friend either messed up your Motherboard by leaning on it, you didn't put all the chords back into the right places. Or both.

Cords seem to be in the right place! had a mate check if they're.

I did try the "Paper clip method" but it didn't work, no fans turned on. Could this be the PSU?

I was cleaning it whilst my friend was watching and he sort of lent on the motherboard (just lighty I hope ) to check what something was.

ShadeSlayer812 :

I just took all the cords and put it all together.. does the exact same.

Your mobo is probably trashed then. sorry but all you can do now is replace it.

Jacob_58 · Mar 15, 2016

ShadeSlayer812 :

Are you 100% sure?

Jacob_58 · Mar 15, 2016

ShadeSlayer812 :

Would that mean i would need a new CPU?

ShadeSlayer812 · Mar 15, 2016

Not if you buy a mobo with the same socket and chipset. You should prob take your computer to a professional.

It would help to know your specs. I doubt leaning did anything. Motherboards can bend and flex.

My Mobo uses AM3+ and i bought a AMD FX-6300 6 Core Black Edition Processor that should be right shouldn't it?

Could certainlybe the PSU if the paper clip test (you're sure you've done it right) does nothing.

There's no zero fan profile on that PSU so the fan should absolutely 100% run all the time.

If you've done the clip test & no power then yes its 99.999999% likely the psu.
Do you have any molex case fans you can plug into it for testing?

You 100% have the front panel case connectors wired right??
As mixing up power reset & power sw would have the same effect.

Jacob_58 · Mar 16, 2016

madmatt30 :

I do indeed have a molex case fan that i could use for testing.
I read the booklet that i received from the mobo and followed its steps for the panel case connectors. Could i try switching over the Power Reset & Power SW?

madmatt30 · Mar 16, 2016

If they're mixed up then in theory the reset button 'should' start the PC.

But yes double check them first.

Jacob_58 · Mar 16, 2016

madmatt30 :

Just Double checked them and put them back into there right spots.. still didn't work

Jacob_58 · Mar 16, 2016

madmatt30 :

Do you need an actual paper clip?

Jacob_58 · Mar 16, 2016

madmatt30 :

When i turn on the PC it shows only the LED light and fans turn on, but if i take out the GPU (GPU lights are on When installed) The Hard Drive Light turns on would this be the PSU failing?

Also could i Borrow a PSU from a friend or would it get damaged? ( just to test things)

Case-included PSUs are basically guaranteed to be junk.
