Dell diminsion E510 power up

It is about 2 years old--yellow flashing light on power up button. Unplugged all from system, plugged power back in and it powered up. Had side cover off and saw fans running. Within 10 minutes, no power. Repeated steps powered up and seems to be running better, but what causes this issue? Is there a problem surfacing that needs to be addressed? How to fix the issue

A few years ago Dell went a little "cheap" when they considered the power supply system on the XPS and Dimension systems. The result is weak or completely faulty motherboard capacitors. They are the small, cylidrical, battery-looking (like if you cut a AA in half) components scattered about the board. The fix is usually not very cost-efficient, in most cases costing more than if you just replaced the entire board. They (Dell) had a recall posted, but I think the time has passed to file a claim. The light turning yellow when it SHOULD be green is a power problem, and with this situation being on a pretty large scale, I'd get the system's PSU and motherboard tested by a local computer repair center. I had the same problem (evidently) and a replacement board cost me around $100 USD. For the local shop to replace the faulty capacitors would've cost me around $80 USD. Good Luck!

Hi stan...

it's possible that there are some loose connections in there... be sure to disconnect your computer from the power source before checking this, or anything else inside your pc. you may want to look at the connections that go from your power buttons to the mother board... don't disconnect them unless you're sure you know how to put them back in the right places. also be careful not to loosen anything else while you do this.

it is also possible that your power box is failing... if this is the case, eventually your pc will just not go on at all. it's not a very expensive thing to replace, i don't know where you are in the world, but in spain the box costs between 20-30 euros and the labour is about the same price.

so first, check your cable connections, and look at the wires to see that they aren't stripped in any places (if that's the case some electrical tape may do the trick) and if all seems ok and the problem persists... you will probably need to change the power box.

hope that helps!

Hello, Last night I shut down my Dell E510 desktop - the proper way - by going to the start menu, shut down, turn power off. Then, today, I pressed the power button on the front of my tower and...


This sounds like a definite power issue. This means that the problem could range from being as simple as the power button itself not working/disconnected to the power supply being dead.

Things to try:

1. Have the side of your computer open and press the power button. Notice if any fans start to move or anything that happens.

2. Do you notice the Hard drive light flashing at all when turning on?

3. Has anyone else been using or been close in proximity to the computer that could have bumped it, causing something to come loose?

4. ONLY if you feel competent enough, check the cable connections inside the computer. Make sure to disconnect from the wall for 30 seconds and reconnect before touching any cables inside. Leaving the cable connected allows the computer case itself to act as a ground to prevent static shock.

Good luck!

Fast flashing yellow light today was


The flashing amber is an error code. Dell Tech support will need to be called in order to troubleshoot as Dell does not publish it's codes. I know when my old E510 did this they started by replacing the psu, when this didn't correct the problem they sent me a new motherboard. Hope this helps.

Computer won't turn on


A flashing yellow power LED is an indication of a failure in the power supply. If under warranty, Dell should be replacing it. If out of warranty, then a 400/450 Watt ATX power supply should resolve the issue.

Dell Dimension E510 Powers Up, Then Crashes


It's the processor or power supply. I cant be sure of which without checking it.

Check the fan over the processor heat sink to make sure its working cause it could mean that the processor is overheating If the fan turns and then it cuts off this could meant that the processor is dead. or the bios is corrupted. Try flashing the bios, there is a battery on the main boad, remove it. unplug the system first... when the battery is out press and hold the power button for 10 seconds then release. put the battery back in and try to turn it on..

If that fails then try a new power supply or one from another system to to check if the power supply is fine. YOu can aslo bridge the green and any black wire from the power supply's mainboard connector to see if the power supply runs. If all this fails then you may need to replace your processor,, I';d also recommend changing the power supply as well.

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
