I know this because none of the functions work on this card, Phys X games crash when I try to run them with it enabled; what is the problem?

problems with updating nvidia drivers-12

What should I do without any Physx and the old one, which makes users unable to delete the latter manually.

With Driver Booster, there is no worry about the problem because the it provides us with the latest drivers and relevant Physx software.

I have no idea how to do right now, should I reinstall my computer system?

But it's too troublesome and I have some important files on my disks.""My graphics card is NVIDIA Ge Force 8400M G.

Driver Booster can not only find out the most suitable drivers, but also help users solve other problems related, such as: the damage of driver's registry, inactive of drivers, driver installer failure etc.

In this case, there is no need to worry about NVIDIA "installer failed" when updating graphics card drivers manually, neither about the problem of inefficiency of old graphics card.

But I heard that the effect of playing Grand Theft Auto V with new drivers can be pretty good, so I decide to have a try.

However, after choosing custom update and deleting those old drivers, I have been failing to install any drivers, including the one I want to update.

Users regard it as a crash and have to restart the computer, leading to the "Nvidia installer faile".optimized by inserting a component of installing reminder.

When choosing a graphics card driver, the program can automatic test if NET is needed by the downloaded drivers, or NET has already been installed.

In case the error is driver-related, it will show up in the built-in Device Manager utility.
