cannot install driver for nvidia GeForce 610M

Hello,
Last week i just bought a new Acer 5750G and i have a problem with nvidia... i tried to install the drivers from the DVD that came with the laptop - none worked, downloaded from nvidia site the drivers - none worked, downloaded from Acer official site - none worked (I tried many versions). Only Intel driver worked so i've sent an email to Acer asking them if i really have nvidia or i paid extra money and got Intel (maybe i'm a newbie but it's my money). Here is a small part from the answer :
''We understand your concern and regret the inconvenience caused to you.

Having verified the records, we would like to inform, your unit is shipped with N13MGE3 NVIDIA GeForce 610M / 1G-DDR3 (128*16*4) graphic card.

The software and hardware device drivers that are pre-installed on an Acer product can be re-installed using Acer eRecovery Management. This can be needed when one specific program is showing a problem, or when you want to revert to the original driver version in case an updated driver does not work as expected.''
But i don't have this Acer eRecovery Management installed on laptop, the DVD doesn't have it and from internet i can't install it...
I tried with Alt + f10 in order to select the original manufacturer settings (as in Acer's manual guide) and it's not working, windows starts normal .
Sorry if i bored you with the novel but in this moment i really don't know what to do.. Any suggestion is welcomed

It seems that you tried to install nvidia driver 285.90 & it failed.
Which driver version is already installed in your laptop?You can check it in nvidia control panel.

In the picture is just an example of 1 driver just to show you what message i get, but i didn't tried only that one , i tried a lots of them and all are showing me the same thing. And nvidia control panel i don't have. I have Intel driver installed (as in the picture) because it's the only one that works

Have you tried these?

I don't own a notebook with Optimus (switchable) graphics. You may need to get the drivers from Acer, if they have used custom device IDs (a common practice in notebooks). The drivers from nVidia may be unable to detect your hardware due to that.

yes i tried and it's not working...it's the same thing as all drivers i have tried

any ideas?
