Scholars,

I have just changed my nephew's PC- a new MSI V motherboard and added
512MB RAM to it.

Everything is ok until when I transported it to his house, the PC can't
be started at all. the power supply can't be started. No power at all.

During the transport, PC is ok and I have transported numerous PC with
car before.

Pls help. Power cable is ok.

Thanks

Open up the PC and re-seat the video card or any other cards.
Failing that, re-connect any other connectors inside of the machine.

Hi,

Is the outlet live? Also check that the back of the PS is still saying
110 volts and not 220. Once those are checked Open the box and check that
nothing has come loose in transport. Make sure all wiring harnesses are
plugged in tightly. Most likely a card or RAM stick is not seated properly
or came unloose. This is a classic case of movis interruptus and is usually
curable.
 
Since it was working OK before you took it to your nephew's house, it's
likely a loose power cable. First, check that the wall outlet/surge
protector/UPS you're using at his house to plug in the computer is live and
supplying power. Then check to see that the female main power cable is
plugged in securely to the external male plug on the power supply; they can
sometimes appear to be completely plugged in but can be forced to go in
another fraction of an inch. Next, open the case to see that the power
cables supplying the motherboard are secure and haven't come loose. Next,
check to see that the front power button pinouts are plugged in securely and
correctly into the corresponding pins on the MOBO. If these steps haven't
located the problem, it could be that there is a metal contact point
somewhere in the case that is shorting out the MOBO/PSU, or you could
possibly have a bum PSU or motherboard. Let us know how things turn out.

Hope this helps,

de rikedee bumps has shaken the shaker and it's all ka-plewee

Test the supply on it's own (search google for how to do it).. Roughly
speaking it's something like removing atx12v cable and jumpering the green
(look it up please) and black wires
ps_on and gnd
if the supply doesnt spin up then I would guess it's POSSIBLE that the
transformer inside of it has gotten broken
not to worry tho
IF that's the problem take it to an electrical shop, ask them to check for
(they'll just touch a soilder iron to them all probably) dry joints around
the transformer..


But really I dont see it being that
I figgure the atx12v main plug has came out slightly or the case switch
connector (or switch itself) was just jiggled out of place during transport.

keep in mind too that you really shouldnt move standard pc's all that often.
if the heatsink uses the retaining clips (these are the compression clamps I
am talking about here) then it's not all that healty.. if the heatsinks are
too heavy then you can damage the chip (heav-n forbid)..

the stock hsf's are usually good for transport but I still think people
should avoid transporting them as a whole unit.
 
Power supply failure. got a new one.

thanks fellow scholars.

Did you check to see if the wall outlet you are trying to use has a current
voltage reading. If you are not getting the proper amount of power voltage
thru your AC outlet then the computer will not have enough current to power
up on.

Good Luck and have a Blessed day.....Karen
 
am going to repair it myself

Doubtful, not if the new psu is working in the unit..
It wouldnt hurt checking the grounding however (since you say your going to
repair your own PSU then I would asume you know a bit about electronics and
electricity)
