I´m new to this forum and I´d like to say hello to everyone round here!
I had the same problem, a GeForce 6200 causing code 43 after VISTA installation (or after one particular Windows update). It´s the first time
that I got to know that Windows 7 has the same issues.
Please try the following:
1. Enter BIOS on starting your system (usually done by pressing F2 or DEL)
2. Go to "Advanced Chipset Features" (I´m not sure if it´s called the same in every BIOS version)
3. Set "AGP aperture size
" value to 128
4. Save your changes and leave BIOS
Afterwards please reboot and check if your video card is listed without code 43 in the device manager.
You should now be able to install the appropriate driver
for your video card if neccessary.
Please find more information on www.code43.de
! Hope this works for you!
Any feedback welcome since I´m trying to find out under which circumstances this problem occurs.
Have a nice day!
