This might not be the correct forum for this, but it will be moved if so :tazz:

I recently had my PC stop booting up. The power button does nothing. I know usually if you have an error in your setup/system your powersupply fans will spin a few times then shut down, but when i click the button, i hear nothing but still silence. (bad, i know!)

Just wondering if someone could help me diagnose the problem. I am literate with computers, and wouldnt mind taking a voltimeter to the supply.

Its really weird, I was up at 2:00am to check a website, then i went back to bed, and the next morning it was off and hasnt been bootable since.

Thanks for input in advance-

Just some basics . . . do not fell comfortable to undertake troubleshhoting :oN LINE" . . .too dangerous for you & PC..

Obvious Checks:

1- Check your power cord at PC & at power strip or wall -
(sometimes they become loose or disconnect - ie. If you
moved/bumped PC

2- Check power strip/wall socket for proper operation by connecting
a lamp to the "outlet" that PC is using . . .unplug PC see if lamp works

3- When were you last inside PC? Did you disconnect & reconnect and
wiring/cables . . . maybe you did not reconnect securely/correctly
or maybe you bumped some wiring to almost off

4- Usually your "power switch" is electronically connected to PS & this
wiring may have been compromised & came loose from previous


1- Read your documentation: on PC - Enclosure - & Motherboard.

2- Check out PC repair books from local Library

3- Visit your Power Supply website . . read FAQ & support page

You should get some good basic knowledge from these items Then you can get back on line . . .armed with good questions to Post here . . .
but I think you will know what you have to do

forget it dude your supply is fried
you already said the one true way to tell
fan spins a few times and quits

back in the 80's i was rebellous and use to work with
my pc on (you just wouldn't believe how many things are
hot swappable if and only if your exact)
so needless to say i have fried upwards of 30 or so power supplys
most of them from touching the bottom of the hard drive against
metal and a few trying to plug in the 4 pin power and missing

i stopped doing this but did learn that when you short a ps if your on top of it (you see a spark) you can pull the power cord out of the computer
to stop the capacitors from drawing to many amps and melting
you get around 6 seconds from spark to pull

sorry i'm having flashbacks

any ways good luck
