Blinking amber power light pc will not turn on replaced power supply

Out of Dell's Dimension 2400 User Guide, the 2350 user guide doesn't list it;

"If The Power Light Is Blinking Amber - A device may be malfunctioning or incorrectly installed

1) Remove and reinstall the Memory modules."

From me;
Ram memory modules. Slang? Ram memory stick.
I would suggest cleaning the gold plated contact pins, on the bottom of all ram memory modules, then reinstalling.

Use a pencil eraser.
If using the eraser on the end of the pencil, and not a solid eraser, refrain from touching the gold plated contact pins with the metal band.

Handle the ram memory module by the Body of the module. Refrain from touching the contact pins.

[ The Body is everywhere but the contact pins themselves. The body of the module is coated with a see-through protective plastic,

{ The Dimension 2350 Desktop PC uses DDR Sdram ram memory, at 266MegaHertz. Or also stated as PC2100. The above example in the link for DDR Sdram above, just happens to be PC2100 ]

Rub each contact with the eraser, both sides. Doesn't take much to clean the surface.
{Doesn't take much 'corrosion' to make a bad contact, either }

Use air to remove the eraser dust.

" 2) Remove and reinstall any cards."

From me;
Cards being any adapter card OTHER than the graphics card. Any adapter cards in a PCI slot.
(For the Dimension 2350 )

"3) Remove and reinstall the graphics card, if applicable"

From me;
If applicable. Means IF there IS a graphics card installed.

Plus for the Dimension 2350, a graphics card will be installed in one of those three white PCI slots.

I have seen a PCI slot burn. I have also seen where the PCI slot was bad, but showed no outward visual signs of damage. Solution was to use a different, available PCI slot.
By the time this is all going on though, the board should be scrapped. (Mobo)

What do the Electrolytic Capacitors on the motherboard look like? Show any outward visual signs of failure?

Plus, just to be sure have you tested the voltages of the new Power Supply?

Isn't actually an accurate test, but if voltages alone aren't what they're supposed to be, the PSU is bad.
(Accurate test is the Power Supply is under a load, then the voltages are tested )

3.3 Volt power rail, (Orange wires), 5 Volt power rail, (Red wires), 12 Volt power rail, (Yellow wires)

Test with a multimeter set to DC voltage. (Function knob set to DC voltage. May be just a DC Voltage symbol. Dotted line over solid line. If there is more than one setting, set it to the 0-50 Volt scale )
An economical multimeter can be purchased for around $6 to $12.

Bad power supply's do get shipped. Doesn't matter if a power supply is new, it can be bad.

Power Supply power cables unplugged from motherboard, (And laid aside so that they are Not near any hardware components ), turn the Power Supply on. See if it at least stays on by itself.

[ Jumper to back of the 20-pin ATX main power cable connector. From Green wire socket hole, (Soft Power On wire), to ANY Black wire socket hole. ( ALL Black wires are Ground wires )

Make SURE the jumper wire goes down into the two socket holes, far enough down to touch the metal terminal connector, at the end of that wire.
Preferred jumper wire is a straightened out paper clip, bent into a U-shape, and the middle of the U-shape is wrapped with black plastic electrical tape.

But you probably know this, as you had to test whether the problem was the Power On switch, (ATX power on switch), or the Power Supply, before purchasing a new power supply.
{Or did you?}

No to all of the above? Power supply checks out?

Start removing Peripheral hardware components.
Optical drive/s first.
(Computer unplugged from power, Anti-Static Precautions observed )

Then the harddrive. You are just trying to see if the power supply will come on, and stay on, for now.

Ram memory.

If the power supply comes on, and stays on with a particular peripheral device removed, stop.
There is the problem.

I have an E-Machines Desktop 3240. I recently decided to upgrade the 256Mb memory to 2Gb as it was running extremely slowly. We initially managed to get it working much faster on 1Gb but it wouldn't boot...

I'd suggest trying another power supply if you can borrow one. E-machines, while a good brand generally, have long been known for being cheap on power supplies. You might also try disconnecting everything plugged into the motherboard except for the power supply and front panel cables, then see if the machine starts up. It may be that something else is causing the trouble, and it's just a coincidence. It's frustrating when a computer doesn't start because several things can cause the trouble. Parts substitution is the best way to find the culprit. Good luck and thanks for using FIxya!

The power supply generates 3 different voltages for the system. The most common cause of the symptom you are describing is a loss of the 5V supply line. This is an internal failure of the power supply that sometimes can be easily fixed, but the cost of repair is likelt to be higher than a replacement supply. A typical power supply will cost around $40. If you have another system around, swap the power supplies between the two. If the system now appears to work, you have confirmed the problem.

Dell dimension 3000 with winxp os.Want to upgrade my ram from the 1 256mb/400mhz to 2 1gb sticks ,dell site says i can use up to 2 gb.So i power down and intall the 2 ddr2700/333 sticks that are required...

Your memory modules may be ECC or Registered (which are mainly used for Servers). They will fit in the slots, but your System will not post with them. I would suggest returning the RAM you purchased, and replace with 2 x 1GB DDR PC3200 400MHz non-ECC Unregistered Memory Modules. A matching pair is preferred.

If you receive a "Memory available limited to 256MB!" message after installing more than 256MB, enter BIOS (F2) and turn OS Install to OFF. Exit saving changes.Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

You may also wish to update to the latest BIOS for this model from the Dell Support Site:

My dell power light was off one morn,but my

Seems to be a Memory or a Motherboard failure. Make sure the memory you upgraded are the ones which are compatible to the system.
The compatible memory modules for your system are:
DIMM, 128MB, DDR2, 400M, 16X64, 8, 240pins
DIMM, 256MB, DDR2, 400M, 32X64, 8, 240pins
DIMM, 512MB, DDR2, 400M, 64X64, 8, 240pins
DIMM, 1G, DDR2, 400M, 128X64, 8, 240pins

The power light not turning on can be the Front bezel issue and not a system/motherboard failure. Please revert for any more issues.

214 - DIMM Configration Warning . Rearrange the DIMMs so that each channel has the same amount of memory >>>???


this is telling you that the Dimms ( Memory Sticks ) Have to be the same or equivalent.
i.e:- 2 x 256mb. 2 x 512mb. Your system does,nt seem to like 1 stick of 128mb And 1 stick of 256mb. et,c.
each channel has to have the same amount of memory. put the same memory in slots 1 and 2 on the motherboard, or if there are 4 slots. put the same memory modules in slots 1-2 3 and 4.
If this does,nt work, use the same memory in slots 1 and 3. or 2 and 4 respectively.

Dell dimension 4700 blinking yellow light

Are you getting any beep signals? You could have a massive motherboard failure or you could be having something a little easier to a memory a little research on beep codes on google if you are getting beeps from the motherboard...Also, try opening your machine and pulling out the memory sticks and trying them one at a time...if the machine works with one and not the other (for example) then you may need to simply replace that bad stick of memory...

Ram memory Problem?

Go to and run the 'Identify my computer' bit, clicking on 'Scan my system' and follow instructions.

The other thing is that if the MAX is 512, you'd want low-density memory.
