Thank you for your reply,

I have already visited links you've posted.

Unfortunately my problem still persist.

After my post here yesterday i had another two BSOD.

GPU device is now working properly in device manager.

Is there a solution for BSOD ?

Sometimes it happens after starting OS, sometimes during regular work (Photoshop, Excel, Outlook, Chrome)

It's really annoying.

And it's big shame if I want to show someone how fast I can boot to Windows thanks to Rapiddrive and then suddenly BSOD appears.

Not very good advertisement for LENOVO...

have you tried to update the drivers directly from nvidia.com?

[vladis]

Yes, my GPU drivers are up to date.

[yigit]

from nvidia.com or lenovo?

[vladis]

When i try to update driver via device manager it says that driver is up to date.

nvidia.com says:

Your PC currently has the latest driver installed for your GPU. No driver update is necessary at this time.

Anyway I have downloaded and insalled 285.62-notebook-win7-winvista-64bit-international-whql.exe

Does lenovo provide some different driver ?

Which should I use ?

[yigit]

in normal circumstances, i suggest you to use lenovo's but if you think there may be something wrong, you should use nvidia's.

but in this case, stick with the lenovo's drivers.

The worst thing is that I am not able to simulate this situation when BSOD appears.

Therefore I don't know if the problem is resolved or not.

I just have to wait for it now.

Anyway I will try your suggestions and let you informed about the results.

Thank you.

Another BSOD while tyring to start game.

Nvidia drivers don't work obviously.

I am going to install lenovo drivers this time.

[vladis]

Lenovo drivers does the same BSOD.

Any suggestions?
