installing 64-bit Win 7 on 32-bit Sony laptop

September 17, 2010 at 12:14:33
Specs: Windows 7
I have a sony vaio vgn-fz15g. My vista os crashed and i installed a windows 7 os. However, i dint know that the windows 7 i was installing was a 64 bit version. I figured that my comp is 64 bit as well since the os worked on my sys.

My problem now is the nvidia graphics driver hasnt been intalled. Ive tried everything but to no avail. I tried downloading the 64bit driver from the nvidia site. I got an error message when i tried to install it. I tried installing the 32 bit version from my backup and i got an error message again.

Please help!!

did you run a compatability check before installing?

start the machine in vga mode, or safe mode, and then check the sony vaio website for windows 7 x64 drivers for your machine. that should solve the issue.

i hate computers!
but cant help myself....

Go back to 32 bit.

This is one of the major issues with 64 bit W7.

Unless you have way more ram than 4G I doubt you would ever benefit from the 64 bit version. Consider going back to 32 bit. There is no test on any web site that proves 64 bit is any better for older computers. When running very new systems with very new software and fully supported drivers you can get a small gain in speed and a great improvement in memory to programs. Oddly enough even the very top end programs are difficult still to configure to get use of potential extra ram.

Why did it take me over a year to phone in a problem to ATT?

This has happened to me long ago and I just had to use this yesterday to get a computer to recognise the graphics card. You can disable any card readers you arent using by navagating to controll panel, then to system, then to device manager, then find 'hard drives', and then right click on the usb card readers(cf reader;ms reader;sd reader;sm reader) to find the 'disable' command . If you only use one certain type of flash ram card you might want to leave that one on, unless you are not using any cards at all. If not just disable all card readers or other devices in the list that you do not use, then shut down, wait for 30 seconds, then turn the power back on. The graphics card should get the recource it needs upon recognition now. This should prove useful in future upgrades also. Just remember the more devices being used the less of a chance a new component will recognised when introduced into the system.

Is your computer a notebook or a desktop ? Did you download the correct driver for desktop x64 or mobile x64 ?

You can do better visiting the Sony support and downloading the driver from there if available, especially for notebooks.

If still no solution, the option of installing the 32-bit Windows 7 is always there for you, especially for RAM less than 2 GB.
