WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Test all leads that attach to your hard drive power and data cables IDE SATA the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical or fan lead can cause you problems motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/ Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink. Hope this helps.

    Check for any obvious damage to the adapter. If any of the outer rubber coating has been damaged so that the conductor inside is exposed, this could allow interference to enter the current and cause a buzzing sound.

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.

My dell e510 started burning when i connected it to a power supply


Hi,
Did it start 'burning' as soon as you connected?Was it loud with sparks?Were you using a power surge protector?
I'd say its a problem of the power supply.
If the machine came with a warrant,and is still on warrant,take it back to have its power supply replaced.If not,have it replaced/repaired at a repair shop.

Hope this helps.Thanks!

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 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.

A few potential problems:

1. Your CPU fan isn't working, causing your CPU to overheat and then turn off the system
2. Your power supply is faulty
3. A capacitor has blown on your motherboard

Give us more details on your problem so we can figure out what's going on

Fix graphics card on Dell Dimension E510


something on the motherboard may be damaged, if you replaced a power supply the motherboard really needs to be checked to see if there is any damaged components on it. my best guess is there are damaged components on it and you may need a new motherboard as well
