Ronzino...forse devi cambiare qualcosa nella configurazione del bios. Ti invio comunque un post del supporto creative per chi ha problemi con le GeForce.
-----------------------------------------
The card should work without any problems try the following options as
there maybe some minor issues to get the card to work.
Depending on the motherboard manufacturers implementation of AGP control,
you may need to use these steps for both AGP and PCI vga cards. Some
motherboards may have different options for the AGP and PCI bus in the
bios, others may only reflect PCI options (for example, Assign IRQ To VGA
could work for both the AGP and PCI bus) that also work for AGP cards
depending on the motherboard. Refer to your manual and motherboard
manufacturer for more information.
In the computer's BIOS, toggle these options (unless otherwise noted):
Video Bios Shadow
Video Bios Cacheable
System Bios Cacheable
C8000 xxxxx Shadow **Try disabling these values**
Peer Concurrency
PCI Streaming
Assign IRQ To VGA **Must be enabled**
VGA Palette Snoop **This MUST be disabled**
Reset Config Data
Enable ESCD
Power Management **Try disabling this**
Virus Checking **Try disabling this**
PnP Aware OS
PCI 2.1 Compliance **Enable This**
(Toggling means trying both enabled and disabled)
Extra Settings for AGP cards;
AGP Aperture set this to 64MB. If the customer only has this much RAM or
less, set it to half of the system RAM.
AGP Turbo **Try disabling this if there are problems with the card**
AGP Fast Writes **Try disabling this if there are problems with the card**
VGA boot from **Set to AGP instead of PCI**
And of course, update the motherboard's BIOS. If your unsure of the
motherboard you have, download the program CTBIOS13.ZIP from
http://www.heise.de/ct/ftp/ctsi.shtml or ftp://ftp.heise.de/pub/ct/ctsi/
and this will identify it.
Motherboard Chipsets/AGP drivers
* Ensure that at least DirectX 6.1 is installed
* The correct AGP driver must be installed for the motherboard and
operating system.
Processor Chipset Operating System AGP Driver
Intel Celeron/Pentium II/III Intel 440LX/BX Windows95/98 Intel
VGARTD.VXD (available in our driver update files)

Cyrix ALI Aladdin V Windows95/98 ALI AGP driver (http://www.ali.com.tw)
Cyrix SIS 5591/5595 Windows95/98 SIS AGP driver (http://www.sis.com.tw)
To install VGARTD.VXD, right click on the VGARTD.INF file within our
driver-update file and click install. If the driver file is a
self-installing executable, it will be automatically installed. This does
not need to be uninstalled before installing another AGP driver (eg. from
ALI or VIA).
With regard to the ALI Aladdin V chipset - you may still have problems,
especially with OpenGL apps. In this case, it may be due to a bug in the
Write Combining Cache of this chipset so you may have to disable some 3D
features in the game to get it working.
Again for problems identifying motherboards/chipsets, CTBIOS13.ZIP from
http://www.heise.de/ct/ftp/ctsi.shtml or ftp://ftp.heise.de/pub/ct/ctsi/
will do the job.
Also remove other hardware and see if you will get the card to work.
You could try the drivers of Nvidia's website and see if these help in
anyway.
