Nvidia 9500 GS gaming problem

[4meL]

Hello everyone
I have a problem with the graphics card more precisely with the games.
When you start any game after 20 seconds maximum I reboot manually, as the image freezes and remains so until it restarts the computer.
I installed the latest drivers from Nvidia, but also appear to me to some Microsoft drivers.

Also system video memory shows me 0

If someone has some advice or if someone had a similar problem post in this topic.
Thank you all.

Most likely you have a power supply that's starting to fail...Do you have a extra one you can use for testing?
