after year of wondering and not been able to install proper drivers for Windows 7 .. i was left with no choice.
hopping over the every forum i spent lot of time..but finally found relief when i took desicion to deal with this on my own..
I have Hp Tx 2009Au tablet pc.with nvidia geforce go 6150 onboard..yes..you are right..it sucks..but bought in 2009 for different reason..i am designer ..well..thats offtrack..
i have not tested this on other laptops with same graphics card.but most probably this will work.
I have managed to alter *.inf for the latest V 306.97 nvidia graphivs drivers..which you can get here.86x and 64x..
follow the process
if you have windows defalut drivers installed and not working as it should..and if device manager does not recognise graphics card model..then
1.install vista drvers you have already.install nvidia n force drivers if required.
why--it will detect the card as nvidia..simple.
1) Download extract the drivers to C:\nvidia
2) Find and replace the disp.inf file the display drivers folder
3) Go to device manager and update the driver using "have disk method"
4) It may show warning that it not digitally signed,ignor and move.
5)you may have to restart if drivers not applied.
you will be able to run windows 8 smoothely.
