Hello,

I have a Dell Dimension E510 desktop and I could be on it for a couple of minutes and then it shuts off. It will try to reboot and after several attempts it will start up again. I thought that it was a spyware issue but that has all been cleaned out at this point but I am having the same issue. I don't hear a fan spinning so I am not sure if that could be part of the problem. I can plug in the computer and it will start without me pressing the power button. I am looking for help to diagnose this problem. If it is the power supply is their a test I can do to check it or if it is a mother board problem is there a test I can do that issue.

Thanks for any help,

It does sound like 1 of 2 problems.
Either the CPU overheating from fan failure or a dirt/clogged heatsink or a bad power supply.
From the " it will start without me pressing the power button." I would suspect the power supply.

Dell power supplies are proprietary so you would need another Dell power supply or one that specifically states "Dell compatible" .
[A "standard ATX power supply won't work]

It will be suggested that you can jump 2 wires on the motherboard connector & test the power supply with a multimeter.
That is a very poor test as all it's going to tell you is.
1. it comes on
2. what the power is at a idle.

In order to be tested properly a power supply needs to be tested under a load,

Thanks for getting back too me so soon. I will try to vacum the computer out and see what happens. I will also look to get another power supply. I have an older dell here but I am not sure if it will fit though.

Hello,

I changed my power supply for my Dell Dimension E510 as instructed and the computer stayed on for a while but it shut off again on it's own. Does this mean that the mother board is done now?

Did you heed,

"Dell power supplies are proprietary so you would need another Dell power supply or one that specifically states "Dell compatible" .
[A "standard ATX power supply won't work]"
?

A standard power supply will plug in BUT a couple of wires on the main [big] motherboard connector are different.

If you used a standard ATX PSU & now the unit has turned off & won't come on I would say the motherboard is probably damaged.

Well, It sounds like you have a good PSU & a bad motherboard. :thumbsup:

Seriously, it's been close to 7 years since Dell used a proprietary ATX connector. It went out in the PIII days.

I would much rather suggest making sure a person got a PSU that is compatiblr with their branded unit then just say "get one" .

I recently went throgh this with somebody else & I'm not going to chase down all the info again.

Any ideas on where to get a good mother board? I do notice that every time my computer boots up the Windows Bios screen comes up then it loads the desk top. Also I looked around and the #3 light on the front of the tower is lit. I looked it up on Dell's site and it said contact Dell? Could that be because the mother board is bad?

Thanks for your time.

"I do notice that every time my computer boots up the Windows Bios screen comes up then it loads the desk top. "

It's a long shot but you could try replacing the CMOS battery on the motherboard.

As for a motherboard, Being a older unit you would probably have to buy one off of a site like ebay , which can be a little tricky.

I will try to replace the battery and if that doesn't work I might just have to buy a new computer. Hopefully it can be revived.

Fairjoeblue,

This is a last attempt to try and resolve this issue. I don't think anything is wrong with the motherboard. I was on a Dell website and it said that this can occur if I installed some software or hardware recently. I did install 2 sticks of 1 gig memory and kept the original 512mb memory sticks in. I check the error log report and it kept listing Memory changed and keyboard error. I removed the two 1 gig sticks but it still shut off. Could this be the cause of my problems?

Thanks for any info.
