Question about Dell Dimension E510 PC Desktop

2 Answers

My Dell Dimension E510 is making a "whirring" noise. It whirls loudly when I turn it on, like something inside is struggling to get up to speed. The computer takes more time than usual to become operable and open programs. Then with the computer on, the "whirring" comes and goes, it is more quite, but more uneven. Sounds like it's going fast sometimes, then speeds up and back and forth. I've opened the computer and cleaned the dust out of it. That didn't help. HELP. VHS

So what could make "whirring" sounds in a computer? Motors. What has motors? Fans, Hard Disc Drives, Floppy Drives and CD/DVD ROM Drives. I can't think of anything else. It doesn't sound like a CD/DVD/Floppy drive because you would only hear the noise when it is being used. You blew out the dust but that didn't help? So either a fan is going bad or the HDD is going bad. Listen inside the case and see if you can pinpoint where the noise is. If you can get your hands on a stethoscope use that. If it is the fan in the power supply it would probably be easiest to replace the power supply. The other fans are easy and cheap to replace. If the noise is from the HDD back up your data ASAP and go shopping for a new one. It can not be repaired. If it is the cooling fan for the processor replace that quick too because if it dies you could burn up the processor. Good thing you caught this before damage is done. I will assume this is not some sort of interference coming through the speakers but stranger things have happened. Also check to see if anything inside the case, like wires, might be brushing against the the blades on one of the fans. That is all I can think of right now.

Can't turn my computer on and i have a yellow blinking light on my dell dimension E510


Do you use a surge protector? If you do, try turning off the power supply to the surge protector and switch on again.
There are a number of causes for this problem, the most likely being a PSU problem or a motherboard fault/failure. To check the power from the PSU to the motherboard, you will need a multimeter to make sure enough power is going to the motherboard. Also check the motherboard closely to see if there is any signs of corrosion or blackened areas, which could be caused by overheating components. Check for leaky or burnt capacitors.

After im on it for about five minutes it makes a loud roaring noise and freezes. The noise doesnt stop until i turn it off.


Sounds like a bad hard drive or a bad CPU Fan. Try a different hard drive in the machine, and see if the machine boots up without making that sound and locking up. If it does then that means the original hard drive is bad.

If its not the hard drive then, replace the CPU fan and see if the sound goes away, if it does then you know the CPU Fan is bad.

Smell something burning inside Dell desktop tower.


Is the computer under warranty? If so, take it back.

Otherwise, open it up and follow your nose - find out what burned inside it and try replacing that.

Dell Demension runs great but loud fan noise that takes a long time to shut down. What going wrong?


I had a similar problem with excessive fan noise on my Dell Dimension 5150. The solution was to replace the worn heat sync compound that was between the cpu and the heat sync itself. (£0.99 ebay)

Dell dimension e510 won't turn on


Unplug the power cable from the power supply in your computer and reinsert it. If you still have nothing, most likely a dead power supply.

If under warranty contact Dell? I had this same problem, a new motherboard and fan assembly fixed this problem. Bad capacitors on the motherbard.
