Video Card driver needed? Screen scrambles and computer locks up

[apamment]

I have an old HP Pavilion a6000n PC that came with Vista but I put Win7 on it. The screen occasionally scrambles and the pc locks up. From what I've seen on the internet, I believe I need the correct drivers. Nothing comes up when I search HP site for this particular machine.

Hi:

Install both the nvidia chipset and graphics drivers from the links below and see if that resolves the problem for you.

Chipset:  Install and restart the PC.

Graphics:  Install and restart the PC.

No luck, the problem remains. The screen flickered once and I got a message to the affect of the video card has failed but corrected itself.  Which is an improvement, however later on it crashed entirely.

I would say the onboard nVidia GPU is on its way out.

I don't know if you want to invest any money in such an old PC, but this is my go to video card that I install in old PC's.

This model was made for Dell PC's, but I have used it in many HP PC's as well. 

As a matter of fact, I don't think I have ever used it in any Dell PC I've owned.

You would need a DVI monitor connection, or get a DVI-I to VGA adapter...

For $8 bucks, it should solve your dilemma.

It was the cheapest one I could find for immediate purchase.
