My 510 XL Shuts itself off

Hi all

My computer has started to shut itself off. It seems to do it mostly
when cold. All I know, when it does, I have to physically unplug the
120V to get it back on. The power switch does not work till after I
unplug it for for a few seconds. I do have a hard time believing it
is the power switch on this issue since you have to remove the 120v to
make it start again.

It can not be a operating system issue since I have it stopped at the
BIOS password screen, and it still shut it self off. I have tried
reseating the memory, processor and cards as well as the power supply
connectors. All the fans seem to be running too.

Anyway what is your best guess, motherboard or power supply??

I think this is the link to the power supply.
http://support.gateway.com/s//POWER/...500843nv.shtml
and the motherboard is
http://support.gateway.com/s//MOTHER...521363nv.shtml

Will a off the shelf power supply work in these Gateways? I never had
a PS issue before, but I know back many years ago, they were
propritary to the manufacturers.

Thanks!

The easiest and least expensive replacement is the power supply. From the link
you gave, I am pretty certain that the power supply has a standard form factor,
and you can use a generic standard ATX12v power supply with the auxiliary 12v
connector needed for Pentium 4 motherboards. Except in its small chassis
computers, Gateway has used standard power supplies for many years. Dell and
Compaq did not for a long time, but that is a different story.

Have you cleaned the dust from the inside of the power supply and from the fans?

Thanks Ben.

Yes, I did check the dust. I am not one to keep my machine on, so it
wasn't to bad in there. I have seen a LOT worse :-)

Well I guess I will have to stop in another city to see if I can get a
PS. I don't hink anyone around here carries them. Hmmm, I will be in
St Louis on Wed, and I know there is a place near the airport. I will
check it out.

Circuit City, MicroCenter, CompUSA all have power supplies. Too damned pricey,
though. Newegg and others sell good quality power supplies inexpensively via
mail order. And that is why CompUSA is closing over 100 stores... Ben Myers

Well you got that right about CompUSA. I went to the store near the
St Louis airport, and saw "Going OUT of Business Sale" sign, and only
6 days left. They didn't have a PS.

I did finally pull out the power supply, and turned it on by
simulating a TTL closure with a diode, and it did shut itself off, and
had to unplug and replug the power to get it back on. That makes me
feel better to have a 90% chance it may be the PS and not the
motherboard.

Thanks Ben
