Hi,

Configuration :
HP Pavilion tx2000z CTO NB
Genuine Windows Vista Home Premium with Service Pack 1 (64-bit)
AMD Turion™ 64 X2 Dual-Core Mobile Technology Gold Edition TL-68 (2.4 GHz)
12.1" diagonal WXGA High-Definition HP BrightView Widescreen (1280 x 800) w/Integrated Touch-screen
4GB DDR2 System Memory (2 Dimm)
NVIDIA® GeForce® Go 6150

NVIDIA GeForce Go 6150 Video Driver - 7.15.11.5682
This is the video driver version for my HP tablet(HP Website). But unknowingly I installed the latest version(7.15.11.7770) from NVIDIA through Windows update. And from that time onwards, my touch screen stopped working. It is not recognizing my stylus/finger.
I contacted HP care and they advised me to follow these steps.
1) Uninstall the latest driver and install the 11.5682 driver
2) Bios Flash
3) Calibrate
I am done with the first two steps but still my touch screen is not recognizing the pen. So I couldn't calibrate.
When I contacted the HP care again, they are telling it may be because of hardware failure. My notebook is working perfectly except this touchscreen.

Note : While reinstalling the driver, it asked me - do you need to overwrite the file(s) ? whether this is usual ? or I need to do clean install again in some other way?

Please anyone help me to solve the issue.

Cheers
Arun

I tried that way as well. But after restart i am not able to install the old driver.
I tried in safe mode : old driver installed successfully but it is not getting reflected
In Normal mode : It is saying driver is not compatible (But I am sure this driver is for 64 bit and it is for HP tx200z)

can you please tell me, the best way to install the video driver?
