One of the users had their boxs' power supply overheat..it was just a
bad PS. After noticing that it was overheating we replaced power supply
with "cooler master" PS 380W, which we bought from a retail store. Well
after plugging everything in, we tested the machine and it ran fine.
Well one of the users accidentaly bumped the box on the side and it
just shut down. Tried to turn it on with no success. I came by...and it
didnt want to turn back on. Opened the case...checked if anything was
loose...plugged everything back up...worked until i tapped the computer
on the side of it and it turned off again...with no success of turning
on without plugging all of the cables inside the computer all over
again. Mostly the cables from PS to the mobo.

Had no success finding anything on the net, and I could take it in a
comp store to check it out...but just woundering if anyone would have
an idea of whats wrong.

Thank you up front for help.

Check the heatsink is still securely on top of the CPU. They generally shut
down if they get too hot and in the case of some CPUs, that can be a mere
few seconds.

380w PSU may not be sufficient....I don't run any of my desktops on lower
than 425w and most are 550w.

Make sure that extra unused cables from PS don't touch case and short PS.
It will cause PS to shout off.

Cari, 380W Ps in most cases is more than you ever need.
Unless you run P4 3GHz, Nvidia 78xx, 2Gb ram and few HDs
My last setup had 350W PS with
P4 Prescott 3.2 GHz (they run hot and are power hungry)
1Gb memory, Nvidia 5700 256MB
2 HD's DVD and some other stuff

So there is no need to recommend 550W monster and older computer.
His old PS was running hot and he got 380W PC.
That means his old PS was smaller that that.

Might have a better idea if you could expand on the computer/mobo specs some
more. Is the computer an OEM by Dell, HP, etc.. What was the old PSU's
wattage? An OEM computer's mobo may need a PSU that is the same as the
original or an upgraded version supplied/bought direct from the OEM or find a
smaller computer exchange type retailer. These stores cater to the do it
yourself type, who need a variety of older/newer/refurbished/used, OEM parts..

Well your solution would be fine if the PC hasn't got several USB ports all
being used and drawing power for their devices (scanners, card readers etc
which have no separate power source) most folks I know have more than one
optical drive if not more than one hard drive....

Strangely enough my desktop needs more than 500w... Prescott 3.0, 256mb
nVidia graphics with VIVO, 2gb RAM, 3 hard drives, 1 optical, tv tuner, hdtv
tuner, combo NIC/USB/Firewire.... let's see... USB devices... Canon scanner
LiDE 80, Canon printer i950, Saitek game controller, Sidewinder FFB,
Sidewinder FFB Wheel,12 in 1 card reader, IR Receiver.... 4 fans, a few cold
cathode lights,

Yes, I probably should have gone for the 600w unit.

I would look for a loose wire in the Main Power Connector to the
Motherboard. But, in any case return the PS 380W
and get a new one.

Canon printer i950 - has it's own PS
Other than that, your case needs no more than 500W PS
Remember USB port won't give you more than 500mA, and most controller won't
give you more than that.
But it wasn't the case with OP.

I want to thank everyone for all of the feedback...it turns out that
the power supply was rigged.,..which rearly happens. After testing it
out, apperently it had some loose connections on it...or whatever it
was causing it to loose power when it was bumped a bit. Computer is
working fine with a 420W PS we just added in it....cant slap it to
death any more

Thank you all.
