Upgrading Laptop Graphics Card

Hi,
I have a Lenovo Z570 Laptop, and it has a Nvidea GT540m(2GB) latest updates on driver, and an inbuilt Intel Graphics(1GB).

When I play game with NVidea, the machine crashes.

1. Is there any thing that I should do to avoid crashing while playing game.

2. if not, I am planning to replace my Graphics card to a higher hardware! Is that possible?

This is my configuration
1. 4GB Ram
2. 2GB NVidea Graphics GT540M- with latest Graphics Driver
3. 1GB internal Intel Graphics
4. i3 2nd/ 3rd Generation
5. 500GB HD
6. Win7 64 bit.

  1. Did it crash before you updated to the latest drivers? If not, revert back to the older drivers, as it's possible the "latest" drivers may not be 100% compatible with the card. Also, see if nVidia has an auto-detect tool that will detect the newest stable driver for your GPU (i.e. it may not be able to use the same drivers as, say, a GTX 780).

    As for replacing the nVidia GPU...good luck with that. Most stores (online or brick) don't sell laptop GPUs. Space in a laptop is at a premium; there's almost no free space available inside (even a mini-tower case is a spacious mansion in comparison), which means any kind of replacement card would have to exactly match the dimensions of the old card (even a difference of a few millimeters could mean you can't get the laptop put back together). Power is also a consideration, as you can't just upgrade to a battery with a faster discharge rate and higher charge capacity. And, of course, this is assuming that the "discrete" nVidia GPU isn't soldered/hot-glued onto the motherboard -- or worse, built directly into the board itself -- making it nigh-impossible to remove the old GPU without cracking/breaking something (in addition, of course, to voiding any warranty left on it).

    Thank you for the reply spdragoo,
    I tried reverting back to old driver, and also updated to latest graphics driver but no luck. And I am updating the graphics as and when I get the pop up to update the Drivers.

    As you say replacing the driver might end up in complete disaster too.
    Let me open my Laptop once and check if I can replace the graphics without actually cracking/breaking stuffs like you mentioned! If I have the slot and space I will update you.
    Thanks again :-)
