I have a 2year old HP pavillion with 2.10GHz, 3GB, 320GB, Geforce 8400M GS specs. I recently upgraded from the Windows Vista Home premium 64bit to Windows 7 Ultimate 64bit and can not find a good driver for it. This was assement was redone after installing the latest driver from Nvidia. I tried using the Vista driver but it didn't help. As you can see my graphics driver is holding my unit back. Any suggestions are welcome.
