Recently my system has become unstable, I found out that I need to update Gforce 3 Ti 200 drivers.
I downloaded 53.03_winxp2k_english_whql.exe. and saved it.

I was told”Once the file is downloaded go into Control Panel and locate Add/Remove Programs. The graphics card drivers will be shown there. Highlight the item and select remove. Once removed you will need to restart your PC. When your system restarts, locate the downloaded display driver and double click the icon. It should take you through a short wizard to install the driver and you will then need to restart your PC again. The new display drivers will then be loaded and you may need to change you screen resolution and colour settings to your personal preference.”

But the problem is after removal of the old drivers when I reboot my PC it automatically loads back the old drivers.

What am I doing wrong please?
