I tried that and its still not working. Everytime I try to install the drivers it gets to I'd say 80% or so and then says The service Nvsvc cannot be successfully started. It then tells me to reboot so setup can finish installing, but then it won't load past the windows load screen. I've read on other sites that installing the drivers and physx separately can work, but no idea what physx even is
I don't think your 7600 can support PhysX. It has to be 8 series or later model.
Dude, you have to wait. When you say Windows load screen are talking about the "Welcome" screen, you know the blue-ish screen before desktop.
Uninstall your display driver (and Nvidia PhysX) and delete their folder in C:\NVIDIA in Safe Mode and restart boot to Safe Mode again and use DriverSweeper and Restart your PC. Once you are on your desktop, go to control panel and make sure you don't have these drivers "NVIDIA PhysX" and "NVIDIA Display (under nvidia drivers.)"
If you don't see them then make a "New folder" on your desktop and move the new nvidia driver into that New folder. Once done, right click on the new driver and click "Extract Here"(make sure you have WinRar installed.)
Once done, you will see a bunch of stuff in the New Folder. Look for "setup" and "NvCplsetupEng" and install them. Install the "setup" first because that is your display driver and then the "NvCplsetupEng" this is your Nvidia Control Panel.
Make sure you DON'T INSTALL or TOUCH the "PhysX_9.09.0408_SystemSoftware" because I think that is the one that causes the problem.
Back to long loading screen. That loading screen is where Windows loads all the drivers and stuff. Therefore, if something goes wrong with the drivers or some bugs, it will load really slow. Sometimes it takes like 30minutes or longer.
Let me asked you this, when you don't install any display driver, can you get to your desktop without a problem???
EDIT: I almost forgot to tell you what PhysX is. PhysX is like Physics. If you play video games, you will see some when someone got killed and their body dropped like a ragdoll, a headshot and the body splattered on the wall, or clothing tears like naturally and so on..
