I have Windows Vista Premium edition on my HP Pavilion dv9627cl Notebook. I ran the driver cleaner as recommended. Here are the steps that I followed: 1. Went to the control panel and uninstalled all nVidia drivers. 2. Rebooted and pressed F8 for safe mode. 3. Ran Driver Cleaner 4. Rebooted to regular Windows (at this point, I realized that the screen resolution is changed, all the icons are large, etc, but wallpaper is there) 5. Ran driver finder for nVidia driver (it said: none installed; latest driver available ForceWare 169.25) 6. Went to download site, but couldn't find the specified driver (169.25 is only for Windows 64 bit (I have 32 bit), so I installed what was available (174.16 for 32 bit (set up detected operating system not compatible, exited set up); then I tried the 169.12 (same error: "Set up detected that the operating system in use is not Windows Vista 32 bit ????!?!?!?!") 7. I checked my display settings. Sure enough, the Windows Vista Aero option is gone, I can only display in Windows Vista Basic. What has happened? And, all the icons and every window and everything is so magnified, as if it is still in Safe Mode!!!!!!!!!!!!! I'm really upset. Please help.
