Whoa! Hold the phone here!

[ NOTE*
This may not be good news. Remember, don't shoot the messenger]

Is the Power Supply a direct replacement unit?
Research indicates Sony used Proprietary power supply's.
Proprietary meaning THAT Power Supply was made for THAT motherboard.

To Expound ( IF, the above holds true):

Look at the 20, or 24-pin ATX main power cable of the old Power Supply, and compare it to the one used in the new Power Supply.

Look at the color code of the power wires, and orientation of the power wires, going to that connector.

Use the Lock tab on the side of the connector, to follow the power wire orientation going in that connector.

(Don't know if the Vaio VGC-RA810G motherboard has a 20-pin, or 24-pin ATX main power cable. Suspect it is a 24-pin)

A) 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

B) 24-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

1) Orange insulated wires are 3.3 Volts.
(3 point 3)

2) Red wires are 5 Volts

3) Yellow wires are 12 Volts

4) ALL Black wires are Ground wires

The above two links from Playtool, show the STANDARD placement for the power wires.

With Sony having a Proprietary design implemented, they can switch the power wires around anywhere they wish, in their ATX main power cable connector. (20-pin or 24-pin)

If there is a 12 Volt wire going to a Ground wire, (Yellow wire going to a Black wire), there is going to be a Short Circuit.

Same with any of the other above mentioned power wires, if they are going to a Ground wire. (3.3 Volt {Orange} or 5 Volt {Red}

Start with the Lock tab on the side of the ATX main power cable's connector, to orient where the power wires go. Look at the color of the insulation of the wires. (Color code)

See if they are the same for both ATX main power cable connectors.
(Compare the old Power Supply to the new Power Supply)

Just thought I would bring this up.
You may have 'Let the smoke out' of your computer.

(Bye-bye Processor, Motherboard, Ram Memory, and Graphics Card.
{Supposed to be an ATI Radeon X600XT graphics card. Does not use, or need any external power wire from the Power Supply )

To your question/problem:

Research indicates:

1) You have an Intel Pentium 4 processor.

Make sure the 4-pin ATX +12 Volt power cable, is plugged into the motherboard. (Power for the Processor)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

2) SATA harddrive.
Make sure the harddrive has a SATA power cable plugged in, (15-pin), and a SATA data interface cable plugged in. (7-pin)
[ SATA = Serial ATA]

If the SATA harddrive has a place for a SATA power cable, AND a 4-pin Peripheral power cable, DO NOT plug in a 4-pin Peripheral power cable!
IT WILL BURN UP THE SATA HARDDRIVE!

SATA power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Standard 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Both of the optical drives (CD and DVD burner) are IDE.
They use a standard 4-pin Peripheral power cable.

They also use an IDE flat ribbon cable, (Data interface cable),
[IDE is also known as PATA. Parallel ATA]

http://en.wikipedia.org/wiki/Integrated_Drive_Electronics

The Processor fan, plugs into a connector on the motherboard labeled CPU or CPU 1.
I don't have info on the mobo (MOtherBOard) used, so I cannot give you direct information as to where this connector is located.

It should be located near the Processor.

[My understanding is that there is liquid cooling for the Processor, and a fan also]

How do i install video cards in my emachines ET1352G-03W?


Your machine will accept a PCI-e x16 Graphics card. If you are going to go to high high-end, high-power card, ensure that you have the proper power connectors for the card. Mainstream video cards are powered from the PCI-e slot itself. Also, be advised that your machine only has a 220W power supply, so high-end cards may draw too much power from an already anemic source.

To install the new card, simply power off the PC and unplug it. Open the case and locate the PCI-e slot (closest to Power Supply). Take out the proper blank at the rear of the machine to allow the card to be installed. Install the card and secure it with a screw (or whatever means the case provides). Hook up the card's power connector (if equipped). Secure the case. Move your monitor's cable from the onboard video connector to the one on the new card. Power up the PC and watch the bootup. The Operating System should detect the new graphics card and will install, at a minimum, a generic driver for it. To install the drivers supplied with the card, install the CD/DVD and run the install setup program.

On board video will likely be disabled if you plug in another video card.

Newer video cards require a connection from the power supply to provide additional power not available on the PCI bus to drive the GPU. It is possible that your 350W power supply does not have enough juice, or the rail is bad.

First guess, check the video card for a power connector. Second, check the power supply. Lastly, if you remove the PCI video card, onboard video will likely work again.

Good luck.

these cards do require that additional power be given to them from the power supply. Have you connected the card to your PC power supply via the 3 pin connector and power connector.

Also uninstall the driver via safe mode and let it redetect in normal mode then install the latest drivers for your card. Download from ati.com

Aspire t-180 4-pin power plug


Your aspire does not include a PCI-Express power connector... that's why you'll need to buy an adapter cable that transforms two other type of connectors (molex) available from your power supply into the one you need to feed power to your video card.

You may need a cable like this...

How do i install a better graphics card


Start by Identifying what type of Card you need to buy. The Manual would be Extremely helpful in identifying What type of Video card slot you have. If that option is out you can look in the device manager and that should tell you what type.

There are many types For any modern Cards your Hoping for an AGP or PCIe Slot bare minimum you need a pci slot.

If you have a Vesa or ISA slot you'd be better off spending money on a new Motherboard & CPU

Once you know what type of card to buy PCI, AGP, or PCIe go out and look for the best card that fits your budget and that your PC meets its requirements

Most new Vid cards require a power supply connection or sometimes two or a special power supply adapter in addition to the available card slot PCIe comes in different speeds x1 x8 an x16 Make sure you have the right one that your card needs before buying. AGP likewise comes in 2 varieties AGP and AGP2 they have a different pin count on their edge connector so make sure what connector it has. PCI just about every semi modern PC has at least 2 PCI slots question is are the currently filled with other cards

Once you've purchased your card, you need to determine if you have an integrated video card.
This would be a video connection that is built into your motherboard.
If you do then you need to look up how to enter your BIOS to disable it (Usually pressing<Delete> or <F12> during boot up. Then go through and change the on board video card to disabled

press <F10> to save and exit
power down PC
Unplug power cord
Remove case cover and install new Video card
Replace case cover and plug back in
Boot up PC
Get Operating system up
insert the CD that came with the new card to install drivers and utilities (Another alternative is to go to the website for the GPU or card manufacturer and get the latest drivers) [ often times the drivers on the install disc are already outdated]

reboot ....... Congratulations your need Vid Card is install Now go play that game your dying to beat ;)

Hope this helps
