I have a problem wiht the Drivers Video Card, I have a laptop HP dv6448se and the video card are a NVIDIA Gforce Go 6150, but I can´t found the drivers.

Windows 8 is unfinished and unsupported.
If you are bothering to test it, you should know how to troubleshoot and work on these issues yourself, in accordance with the FAQs about it... (Linked and repeated in this reply later on...)

Having said that, the support for your nVidia Video Device comes from... HP first followed by nVidia (Assembled system OEM and then individual component OEM.) Doesn't matter what operating system you utilize.

According to nVidia's site about Windows 8: http://www.nvidia.com/object/windows-8-solutions.html

The GeForce Go 6100/6150 is supported (or was for the Consumer Preview - so one would hope it would not drop in the Release Preview) under Windows 8.

So...

The 64-bit Windows 8 drivers for the GeForce Go 6150 can be gotten here.

The 32-bit Windows 8 drivers for the GeForce Go 6150 can be gotten here.

Is Windows 8 Release Preview ready for everyone to try?

We strongly recommend that only experienced PC users download Windows 8 Release Preview. Before you download the preview, you should weigh the pros and cons of installing software that's still in development. If you install the preview release, you'll get to try out the many new features, but you might also encounter errors that you wouldn't encounter using a released version of Windows.

You should consider downloading the Windows 8 Release Preview only if all of the following apply to you:
* You like to use the latest software and enjoy experimenting with new technology. *
You're comfortable backing up a PC, formatting a hard drive, and installing an operating system from scratch. *
You feel comfortable troubleshooting PC problems yourself. *
You don't mind updating software frequently. *
You have the installation or recovery media and the knowledge to restore your previous operating system after you're done testing Windows 8 Release Preview.
