I have just gotten a HP Pavilion dv9535us (a variation of dv9500t). It has an Intel Coe 2 Duo T7300 processor in a GM965 chipset with the Graphics Media Accelerator X3100.
Since so much of my CAED stuff is not yet Vista compatible, I wiped the hard disk and installed Windows XP Professional.
I downloaded that latest GMA driver (v14.29). The installation completed normally, but on reboot after the Windows logo, the screen goes black with a bright spot on the upper right corner. The system does not hang.
I am currently running the driver provided by HP i.e. SP33889 (which is GMA v14.24) but as G965 (which I believe is the desktop version). The 17" screen is running in 1440x900 as it should.
I found a posting describing the exact same situation, so apparently this is not unique.
Interestingly, the Chipset Identification Utility fails to make an identification.
I don't understand what is going on. Can someone please shed some light? HP tech support has no clue.
