SONY VAIO VGN-BX570B – Video Driver

by on November 20, 2009

All who stumble upon the need to install the VGA driver for your SONY VAIO laptop. If you ended here for some help with that, it means that the driver is still not on the Sony web site where it is supposed to be. Anyway I had the same problem and of course I have searched everywhere. Eventually I found Driver Robot and gave me a name on the actual chip. I already tried the ATI website and their tools did not work. In addition I tried to get Sony to fix it for me because on their website they have 15 min free tech support. It takes them less than 15 minutes to really up load the driver on your computer and a text file with instructions, but they don’t want to do it. They BS around until the free 15 minutes pass by to no avail, and then they say that for 24.99 they will install the driver to your computer.

But before that I had a Sony tech looking in my computer remotely and the only think he did was restart my computer. And he looked somewhere in the registry. Anyway the Driver Robot did it. I was able to download the driver and install it from its setup file, but when I restarted the computer the driver could not be loaded. Then I kept on researching to find out where the problem was because Device manager was giving a code 41. I found some help online where I had to delete some registry settings. I delete more than two settings because there were more than two registry keys with the identical name. When I restarted the computer, the driver was detected but nothing else worked.

No mouse or keyboard working so I had no possibility to interact with the machine. How did I know that the VGA worked when nothing else did? I knew it because there was a screen message where would let me know that the ATI control panel was loaded and the resolution was the max resolution supported by the display. So I tried safe mode to no avail. Therefore my friend suggested Winternals ERD commander and do a system restore. Did that, and the driver was gone but I could interact with the machine again. This time I just upgraded the driver by browsing to it’s location and installing from the location instead of running setup. Worked like a charm.’
Good Luck.
Here are some links to the driver:
Also you can look the same driver up on and look for “ ”
If you install the driver from location and still is not working the you need to delete the two settings in the registry, the article can be found at the following web address:
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:
On the Edit menu, click Delete, and then click OK.

Locate the LowerFilters value under the same key in the registry:
On the Edit menu, click Delete, and then click OK.

If you do this make sure you have ERD commander so you can recover the OS to a previous state and make sure you have system restore enabled, and make a restore point before you delete the registry settings.
In addtion make sure that you delete the upper and lower filterrs in the registry keys 4D36E965-E325-11CE-BFC1-08002BE10318, and only in the ones that contain something like this value: Instaler32   — — Desk.Cpl,DisplayClassInstaller. Because these contain something about display adapter. The others contain mouse value or other peripherals and therefore you might end up in my situation where no input device works. Be careful. Also this we already know ,that I am not responsible if something wrong happens with your device, and you do this at your own risk. 🙂 .
