Lenovo U460 shutdown unexpectedly in Swichable graphic mode

Question

Hello,

I'm using U460 with win XP. I used it for long time without any problem.

But recently, It shutdown randomly.

Especially, when i was watching video with flash on web, and do action quickly (such as swich browser tabs quickly...).

So I think there is problem with graphic card or Its driver.

 

Then I try to research, I changed  Swichable graphic to Discrete Graphic in Configuration.

after that it come to be better. No shutdown randomly anymore. And the screen is not "blurs" anymore when i do action quickly.

 

But The screen is rendering slowly. I can see the images of screen is loading from top to bottom,

I installed all drivers for win xp but in "Device manager" It still doesn't recognize Video Card "Nvidia".

 

So i just want to ask:

- Is there any way to Nvidia card can work good in XP?

- If not, Is there any way to i fix the issue with Swichable graphic mode?

 

Any idea would be very appreciated!

Answer 1

In win XP, you can't use Ndivia Video Card, because it don't have a proper driver for win XP.

You you should disable this video card in Device manager.

- Try to install latest driver for your Intel onboard card.

- Try to change screen resolution to a smaller resolution.

If above steps still don't help
