Believe problem to be one of the Power MOSFET's, in the DC - DC circuit on the motherboard

http://en.wikipedia.org/wiki/DC-to-DC_converter

Using the HP Pavilion dv6000 series and Pavilion dv9000 series, of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

The two Power MOSFET's used; are the Fairchild Semiconductor Industries -FDS6679 - Power MOSFET, and the Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET.

Showing availability and cost. Using just FDS6679 for an example,

http://www.mouser.com/Search/Refine.aspx?Keyword=fds6679

Obsolete. Using cross reference match example,

http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FDS6679AZ/?qs=sGAEpiMZZMshyDBzk1%2fWi1qxDdW%2fXBi2qgMuZEfLVO4%3d

One dollar and one penny USD.
AO4407 is obsolete too. Cross reference match example for it, cost is 78 cents USD.

NOT stating the P.MOSFET's are used on your Sony VAIO's motherboard. Showing what a Power MOSFET looks like for this type of application, and availability/cost.

Look on your motherboard in the DC - DC converter circuit area, where the DC Power Harness plugs in.

[The AC adapter (Charger), plugs into the DC Power Jack on the laptop. (DC_IN)

For your laptop the DC Power Jack is connected to wires, that end in a male plug connector. The male plug connector plugs into the motherboard.

It is now called a DC Power Harness ]

Let's take a brief look at a motherboard example,

(Sony VAIO PCG-6L1M and VAIO VGN-B1VP are supposed to be the same)

The Main view shows up automatically, with the Top view of the motherboard.
Scroll down for Bottom and Top view.

Again there is a Main view, and this time two smaller views to the Right.
Top small view is Top view of motherboard.
Bottom small view is Bottom view of motherboard.

Looking at Bottom view of motherboard, believe DC Power Harness plugs into the Right side.
Series of Power MOSFET's are on the right side, also.

WEAR an ESD wrist strap, and have it's alligator clip attached to a good ground source.
Here is free access to the Service Manual.
You want VGN-B

Bottom line -> VGN-A
Scroll across, click on VGN-B

Hello here is the homepage:

http://www.sony-asia.com/support/product/VGN-FE45L

Here is only drivers for windows vista, but the drivers sometimes work for windows 7.

Please select your windows system 32 or 64 bit.
And download one of the update programs.

Good luck

First step is to hook it to an external monitor. If the monitor has signal, then you should be able to re-seat the video cable on the system board. If not, then something internal, like the motherboard, is defective.

The Manual for your Sony VGN-325E can be downloaded here

Please remember to rate my solution to show your appreciation.

I'm assuming you changed to Win 7 Home Basic or Premium 32bit System.

First we have to figure out which VGN-CR420 model you have, to do this look on the bottom of your VAIO for the Model/Serial Number tag. On it you should see something like this:

1. VGN-CR420E
2. VGN-CR420E/L
3. VGN-CR420E/N
4. VGN-CR420E/P
5. VGN-CR420E/R
6. VGN-CR420E/W

Now that we have the model #, we can get your drivers.

First we will get your Webcam drivers:

Now were at Sony eSupport, go to "Software Drivers" (leftside middle of page) click on it. > Option 1. > Choose Country if not USA > Type in Model: VGN-CR420E (use your on model) then click "Continue" > Select Your Operating System > Now we are on your VAIO's page. Look for Camera then click it, the driver file is the "WebCam Companion software" download to you desktop. (easier to find) Open install, Done!

There is other good stuff here so bookmark this page!!!

Now for your Bluetooth driver:
