Hi my name is Joe, recently my Emachines W3507 Ive opened cleaned and put plugs back in ... I believe I put them in all correctly but its startup on the computer its self isnot working So I began looking around and saw these 3pair of coards. Ive researched them up Realized that could be the problem. The coards are labeled (Red+White) H.D.D Led, (Green+White) Power Led and last but not least (White+black "might be dark blue") Power sw.. I See the correct place where to place them I just dont know what way I have to put them in or what order.. So Please help me Id be honored and if this works correctly I shall tell friends/family etc. About your fast support! Please help Thankyou!

Can you clarify the question?

What plug ins?

On most PC's, shut down your machine, wait a minute or so, power it back up and start tapping the F8 button until you see the prompt for safe mode.

the cable connectors are the same color as the pins were they go.

Most of the reasons for automatically shutdown are lack of cleaning or cooling. Clean your computer and put one (1) drop of thermal paste on the cpu core. Also your system files are corrupted or infected by viruses.

Please rate me

The eMachines W3507 uses an Intel D102GGC2 motherboard.

Yes it does. It's a DB-25 parallel port.

Look at the I/O area on the back of the desktop computer.
(Input/Output)
The Green PS/2 port is for the Mouse. To the right of it is a parallelogram shaped port.
Pink in color, 13 pins across the top, 12 pins across the bottom.

If you get nothing but a blue light and no video at all it sounds like you have a bad power supply. They are easy enough to check and replace but not for a first timer. If you know someone who knows more; get a volt meter and put it on the DC scale. Unplug a power plug to a drive or find one that is not used. Measure the Yellow to black and then the red to black wires. You should get 12 & 5 volts respectively.

You can purchase recovery software specific for your machine (you will need your computer's serial number) here:

I believe it is around $20, plus shipping costs.

Hope this helps.

Update the drivers to the correct card .

There may be a hole but it will be under the lip of the door, kind of impossible to get to. You may have to remove the drive from the emachine and unscrew it and open it manually with a small screwdriver. I regularly buy and repair or use parts from used samsung drives which is what emachines uses almost exclusively. The only upside to this is that once open, you can swap the faceplates and doors onto newer drives. If the led light is not in the middle then you can swap out the little plug in circuit too.
