Dear sir, i owe a sony vaio VGN-CR31S/L and want to completely uninstall windows vista 32 bit and install windows 64bit. But the problem is im looking for all the drivers and still didnt find them. i checked in sony sites but yet not results. so could you please help me in locating all the drivers for my laptop which wil be compactible with windows 7 64 bit...

There probably is not a driver specifically for Windows 7.
Usually you will have to use the one for Windows Vista.
Windows 7 is only a glorified version of Vista anyway.

Go here:Drivers
Select the Downloads tab, then select the operating system.
If you have 32 bit Win 7 then select the 32 bit Vista.

If you have home premium then select the same for Vista.

In the next drop down menu select Original Driver.

There is one for Vista called camera module driver

You need the Win7 camera driver, check sony support at:

just enter your Win7 operating system (there are 9 versions of Win7), and select the downloads (2)

Versions of microsoft Win7 - determine which yours is by (these instructions are for WinXP);

Try install the WEBCAM driver for you Sony VAIO found here:
http://b2b.sony.com/b2bMicrosites/landingpage/vaio_drivers/download_vaio_drivers.html

Most likely missing a driver for SD/MC card reader
The problem is that Sony doesnt offer drivers for 64-bit windows so the other 32-bit drivers will not be compatible.
You have the options to install the windows versions supported by sony from esupport.sony.com (Vista or XP)
Or try installing windows 7 32-bit and installing the missing drivers from esupport (Vista section) as usually they are compatible.
If the driver is still missing you will need to update the driver from device manager (previously installed from esupport) and then select to browse or select a location, which will be %temp% or what is the same the temp folder for your account C\users\your_user_name\appdata\temp. This folder is usually hidden but it will work if you just type %temp%

I have this same computer. Didn't it come with 32-bit Vista, cause mine did. The hardware of the camera may not be compatible with 64-bit. Also, did you do a clean install? Cause that's what I did by mistake when installing Windows 7 and none of my hardware worked. I ended up switching back to Vista because Sony did not provide any drivers for Windows 7 for this computer.

You may try with these troubleshooting steps.

These steps are applicable for either Windows XP or Vista OS. But you can perform the same in the Windows 7 OS.

Option 1: Try installing Sony Registry Update for CD/DVD Drives:

http://esupport.sony.com/US/perl/swu-download.pl?mdl=VGNNR180E&upd_id=2031&os_id=28

Option 2: Try deleting UpperFilters and LowerFilters Registry values as mentioned:

The exact solution is delete the UpperFilters and LowerFilters Registry values and then restart the Computer.

Good Luck!!!!!!!!!!!!!!!

Answer 1: The 64-bit version of Vista includes a 32-bit bubsystem to run 32-bit apps. I have not encountered a problem with it yet.
Answer 2: The power is consumed by hardware, not software, so with the same power settings you will see no difference in battery life.
Answer 3: Sorry, I couldn't locate any information about that model. You may be able to find appropriate drivers from other sources by pulling all available details from your existing drivers and searching the mfr website for them.
