Pull the ram out again and reinstall making sure that it is seated firmly and both catches are closed. Other than you tearing wires out it seems like the likely suspect.

When i try to turn on nothing happens front light just flashes white then blue nothing on screen

It sounds like you may have either a defective video card or RAM. To test the RAM, open up the RAM bay on the bottom of the laptop and remove one stick. If the computer still isn't starting, swap the stick that you took out with the one that is still inside. if that didn't help then you should take it in to the manufacturer for repairs. NOTE ABOUT HANDLING RAM: RAM is very sensitive to static electricity so be very careful not to touch the gold leads on the bottom. Good luck!

My computer is beeping two short beeps and will not boot. I have taken the back off the cpu. What do i need to do?

Suggest you remove the Ram Memory module/s, and clean the contact pins on the bottom, then reinstall.

What you hear are BIOS Beep Codes. The computers way of telling you something is wrong, and the area to look into for it.

This is Dell Support > Inspiron 531s desktop computer > Owners Manual > Troubleshooting > Beep Codes,

After time, the contact pins on the bottom of the Ram Memory module/s ('Sticks') can develop corrosion.
The corrosion prevents a good contact.

According to the specifications, the Inspiron 531s uses DDR2 Sdram ram memory modules.

(DDR2 Sdram at a frequency rate of 533MegaHertz.

DDR2 Sdram has 240 contact pins. 120 on each side.

The example below is DDR Sdram, which has 184 contact pins. 92 on each side.
The example is given to show you a close-up, of the gold plated contact pins I am referencing to,

(You can left-click on the photo to enlarge)

Suggestion is to take a pencil eraser, and stroke in a downward fashion on each contact pin, towards the bottom of the ram memory module.
('Stick' is slang for Module)

(The top of the ram memory module, is above the black rectangular DRAM chips, on the side of the ram memory module.
The contact pins are on the bottom side)

If you use an eraser on the end of a pencil, refrain from letting the metal 'cap' touch the contact pins.

Refrain from touching the contact pins. (Static)
The body of the module, is coated with a see-through protective plastic.

After you have cleaned each contact pin, use air to remove the eraser dust.
You can use a can of compressed air for computers, or air pressure from your mouth may be sufficient.

BEFORE you begin to remove the ram memory modules, or reach inside your computer; and computer unplugged from power, observe Anti-Static precautions!

Anti-Static Precautions:

Your body carries Static electricity.

Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

(Hardware components examples, such as the Processor, Ram Memory, Harddrive, Motherboard, and graphics card/s if used)

To relieve your body of Static, TOUCH the metal frame of the open computer case.
(Computer unplugged from power)

Should you leave in the middle of working on your computer, upon your return be Sure to TOUCH the metal frame again.

An alternative method, (Best method actually), is to use an ESD wrist strap, and connect the alligator clip to the metal frame of the open computer case.
(Computer unplugged from power)

Electro Static Discharge.
One example of an ESD wrist strap,

Computer unplugged from power, all cables removed, I would lay the computer on a towel, on a table, and the case side that is open, facing up.

Easier to access those ram memory modules.

[ If you are not perfectly sure, where each cable plugs into on the back of your computer, now would be the time to make a drawing, and notes, before you unplug them.
Especially any audio cables that plug in ]

Removing and Installing Components: (Parts)

If you left-click on - System Board Components, you will get a basic idea of where the ram memory slots are located.
(4, 5, 6, and 7)

If you go back to the main menu, and left-click on
Memory, you will be guided in removing, and reinstalling the ram memory modules.

If you have any questions concerning this, or need more of a simplified explanation concerning anything I have stated, simply reply by posting in a Comment.
(Believe upper right of your page)

If cleaning the ram memory modules does not cure your problem, then I suggest you remove all ram memory modules, and reinsert one at a time

Test each ram memory module to see if there is a bad one. (Or if they all are bad)

Remove all ram memory modules, insert just one module in Slot 1.

(Place the unused ram memory modules, on a non-Static surface. Wood is one example of a non-Static surface)

On the System Board Components illustration, Slot 1 is referred to as DIMM 1.
(The number 5 points to DIMM 1)

The Processor reads Slot 1 first.

Procedure is, computer unplugged from power, install the ram memory module.
Plug the computer back into power.

Remember what I stated about Anti-Static Precautions.
To plug the computer into power, you may have to leave the seat you're sitting in.
TOUCH the metal frame upon your return.

Turn the computer on. See if the ram memory module is good. (No 2 Beeps)

Ram module checks out, shut the computer down normally. (Start> Turn Off Computer > Turn Off)
Unplug the computer from power.

Observe Anti-Static Precautions.
Remove the ram memory module. Place it on a non-Static surface. (Wood)

Insert the next ram memory module. Plug the computer back into power.
And so on.

Motherboard for compaq pcsr5109uk have upgraded to 1,5 GB this adding a 1 GB ram since doing this pc will not boot up,pc has said that the mother board has died this has only started since new ram have...

From what you have stated, the original ram memory was two sticks of 512MB.
It's PC2-5300
(DDR2 Sdram at 667MegaHertz)

When installing ram memory, and installing two sticks with one stick being larger, the larger stick of ram memory is installed in Slot 1.

This is the ram memory slot that is closest to the Processor.
(The Processor reads Slot 1 first)
On the motherboard it has DIMM 1 printed next to Slot 1.

The 1GB stick should go into Slot 1 (DIMM 1), and the 512MB stick should go into Slot 2 (DIMM 2)

Scroll down for the motherboard illustration, and photo.

Won't boot up with the original ram memory installed again?
1) What type, and size of 1GB ram memory did you install?

2) What ram memory slot did you install it in?

3) Did you follow anti-static precautions BEFORE you put your hands inside your computer, and BEFORE you took that ram memory stick out of it's protective anti-static bag?

[Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.

You may not even see it, or feel it.
No computer.

Computer unplugged from power, computer on a table, computer case open, TOUCH the metal frame to relieve your body of Static.

{A couch, bed, or directly on a carpet floor are HIGH areas of Static]

Before you answer my questions try this;

If the two sticks of 512MB PC2-5300 are still installed, follow anti-static precautions, and remove them.

Take a pencil eraser, and clean the gold plated contact pins on the bottom of each ram module. (Stick)

(The above example is DDR Sdram, not DDR2 Sdram. I posted the link so that the gold plated contacts are clearly shown.

DDR Sdram has 184 contact pins.
92 on each side.
DDR2 Sdram has 240 contact pins.
120 on each side)

Remove the eraser dust with air. Use a can of compressed air for computers, or air pressure from your mouth.

Reinstall the ram memory modules.

Computer unplugged from power, press the Power On button in.
Hold the button in for a count of Five seconds.
(Count 1001, 1002, 1003, 1004, 1005)

Let go of the Power On button.
Do this procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS back to the factory settings.

Plug the computer back into power.
WAIT 1 minute, then turn the computer on.

I await your findings, and answers to my questions.

Can I install one (1-gig) memory stick instead of 2 match pairs (only have one) this is to replace two 256 sticks?will it preform at 1 - gig memory


The Maximum Total Amount of Ram Memory is 2GB.
The Maximum Amount for EACH ram slot is 1GB.

Ram should be installed in Slot 1, when using just one stick of ram.
This is the ram slot closest to the Processor.

The Processor reads ram memory that is installed in Slot 1, first.

This is Dell Support, and the main support page for the Dimension 3000 desktop computer,

In the list left-click on - Technical Overview

Now click on - System Board Components

Number 1 is Slot 1.

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate computer hardware components inside a computer.

Work on a table.
After you have opened the computer case, and BEFORE you remove that ram module from it's anti-static protective bag, TOUCH the metal frame of the open computer case. (Power unplugged from computer)

This will relieve your body of static.
Ignore the above if you are already aware.

How to open my Dell Dimension 4600 to install two new gigs of ram

1) Computer off, and disconnected from power.

2) Disconnect all cables leading to your computer.

3) Lay your computer down on a table. Lay the right side towards table.
(I like to lay a clean, static free towel down on the table first, to prevent scratching the computer, or the table)

4) You are now looking at the back of the computer, with the power supply fan to the Left side.

Look underneath, along the top edge of the computer case. There is a computer case cover release latch, on the Right side. Pull the Cover Latch to the Right.

Now pull the side cover towards you. (Towards the back of the computer.

Lay the side cover aside.

BEFORE you reach inside, or take the new Ram Memory sticks out of their protective, anti-static bags, TOUCH the metal frame of the computer case!

Your body carries Static electricity. Static can fry out your computer hardware components.
Touching the metal frame of the open computer case, will relieve your body of Static.

Should you get up, walk away, then return, TOUCH the metal frame again.

Refrain from handling Ram Memory sticks by their gold plated contact pins. (Bottom of ram stick)
You can handle the ram stick anywhere else, as the body of the ram stick is coated with a see-through plastic.

6) Dell Support > Dell Dimension 4600 Series > Manuals > Service Manual,

A) Left-click on - Removing the Computer Cover

B) Go back to this main menu, and Left-click on -
Removing and Installing Parts

Now Left-click on Memory.

Not trying to insult your intelligence, but if you have never installed Ram Memory before:

Your computer uses DDR Sdram ram memory modules, ('Sticks')
(Double Data Rate - Synchronous Dynamic Ram Access Memory)
A DDR Sdram module has on Notch on the bottom.

The Notch looks to be centered upon a cursory glance.
It is Not.
The Notch is over to one side a little.

(Actually a DDR Sdram ram memory module has 184 contact pins on the bottom.
92 on each side.
The Notch is located in-between Pins 40 and 41.
40 pins on one side of the Notch, 52 on the other side)

The Notch must be lined up correctly with the Locating Lug, in the bottom of the ram memory slot. The ram stick only goes in, in one direction.

There is a lock on each side of the ram slot. White in color, looks like an 'Ear'.
Dell's reference to a lock is 'Securing Clip'.
Put your thumbs on the top of each lock on a ram slot, and gently push down, and out.
The lock pivots to the outside.

When the locks pivot, the ram stick is raised up out of the ram slot.
Upon closer examination, you will note a small slot at the bottom of each lock.

The bottom corners of the ram stick, fit down in these slots.
Set the ram stick down in the slots of the locks, Notch lined up with the Locating Lug.
Push down on the outside top corners of the ram stick.

When the ram stick is fully seated, the contact pins will be down in the ram slot, and the locks will be seated against the sides of the ram stick.
You will notice that each lock has a 'Bump' on it. This Bump lines up with a Notch on the side of the ram stick.

The bump must be in the notch, for the ram stick to be fully seated.
Usually you will hear a satisfying 'Click - click', as the lock's bumps click into the notches.

IF, the ram memory slots that you are installing ram memory in, have never been used before, they may be tight.
You are installing new ram memory modules.
Makes the fit even tighter.

Sometimes it's a 'Pee Picker,' to get those ram memory modules to go in.
Makes beads of sweat pop out of your forehead!
Other times they slip right in with No problem.
Thought I would warn you in advance.

If I understand correctly, do I understand you are installing TWO - 1GB sticks of DDR Sdram?

[DDR Sdram at 333MHz {PC2700}, or DDR Sdram at 400MegaHertz?

1) If the ram memory modules that you are installing, are larger than the ones already installed, install the 1GB ram modules in DIMM 1, and DIMM 2, ram memory slots.

DIMM 1 is Slot 1.
Slot is the ram memory slot that is closest to the Processor.
The Processor reads Slot 1, First.

DIMM 1, and DIMM 2, (Slot 1 and Slot 2), are a matched pair of ram memory slots.
They are in the same Channel.

Desktop with 8KDA dead so replaced power supply but still dead. Electricity still coming to computer but no signs of life. ?

First, power down your PC, remove the power cord and then remove the RAM from the computer. Now turn the computer on. If it doesn't beep at you several times, you have a bad motherboard.
Note: When doing any work on your PC, make sure you disconnect the power and touch some metal on the case to remove static from your hands.
If it does beep at you with the RAM out, the motherboard is OK.
First, before going too far with testing, try simply putting all the RAM back in and turning the computer on. The process of removing the RAM and reinstalling it is called re-seeding. Sometimes re-seeding the ram is all you need to do.
Note: You can also try re-seeding other peripherals, but we will get to that.
If you still aren't having any luck, you will need to test each stick separately.
To properly test the ram, remove the power cord from the computer, remove all peripherals (videocards, sound cards, modems, tv tuner.. etc) and disconnect all drives (hard drive, dvd/cd, floppy).
If you only have one stick of RAM, leave that stick in and turn the computer on. If it boots, the problem isn't with the stick, but with one of the peripherals.
If you have multiple sticks of RAM, you will need to test each stick on it's own with all the peripherals disconnected.
If your RAM is ok, you can now single out which peripheral is giving you an issue by adding them back in one at a time and trying to boot your computer.
If your computer is now booting with everything in it, your computer simply needed to have everything re-seeded - lucky you!

My monitor is flashing blue on and off at the power button

If the screen is black, then there is no data going from the computer to the monitor. If this is the case, your computer may not be starting properly or you may need a new videocard.
If your computer is not starting properly, you can try re-seeding the ram (taking it out and putting it back in).
  • Open your case remove the power cord from the PC
  • touch some metal on the case to remove static
  • take the ram out.
    Note: if you have a white eraser, this would be a great time to clean off the gold leads on each stick. Use the eraser (as you would normally) on the leads to make sure they are nice and bright. Be careful not to touch the leads with your hands.
  • Put the RAM back in,
  • reconnect the power and turn your computer on.
If this doesn't work, and you have many sticks of RAM, try connecting using just one at a time to test and see if a stick is bad.
If you have a stand alone video card, try re-seeding it just like the RAM. You can also clean off it's leads in the same way as the RAM.
The only other thing it could be is a dead motherboard. To check for this, remove the ram and turn the computer on. If it beeps, it's working and something is wrong with either the ram or graphics card. If it doesn't, you need a new motherboard.

One Short beep and two long beep

The beeps you hear are BIOS Beep Codes. Sort of like a Morse code, if you know what that is. Every computer has it's own BIOS program, and version of that program. Each BIOS has it's own Beep Codes.

Taking a guess, as I don't know what BIOS program or version you have, it sounds like a ram memory issue.
Suggest you,

1.Unplug the computer

2.Open the computer case

3.TOUCH the metal frame of the open computer case, to relieve you body of Static electricity. Static will silently fry out your delicate computer hardware components. You won't see it or feel it.

4.Remove the ram stick/s. Reinstall the ram stick/s. (Stick/s means one ram stick, or two, three, or four ram sticks)

You may have just had a loose ram stick.

Won't turn on

if you are able ,open the box,earth yourself out on it (static can damage things) if you have more than one stick of ram take them out ,and try booting up with one stick at a time, in the first ram slot ,if you find one that does not boot the system up its the bad one ,reinsert what ever other sticks you have , problem solved.

if not ,replace all ram chips, then

  • remove any ad in cards that you have, one at a time (other than a video card if you have one) then try booting,
  • if you have gone through all the cards (not the video as mentioned before) and still not booting, remove everything including the video card ,ram, disconnect all drives ,
  • if you hear no beeps then the most likely problem is the motherboard ,
  • but have known power supplies that fluctuate to cause the same problem.
good luck
