Windows 7: Dual graphics problem, system doesn't detect my nvidia 620m

Hello guys,

Today i made a bad thing, i tried to install windows xp 64x , i did it, i download some drivers for it, then i couldn't find Nvidia driver for it, so i format everything , set bios to default,

My next step:
I reinstalled windows xp 64ultimate , I installed drivers from Laptop DVD everything is fine but again same problem, The driver for 620m doesn't works it doesn't detect my graphics driver, even the graphics detector from nvidia site can't detect my driver

So what's wrong, i don't get it have you any idea how i could fix it?



I added my system components on the left so you can check it

i checked internet , i just found a guy who was same problem as me

with same procesor 3110M , but i've found no answer to this problem

I'm thinking if the last driver is bugged or smth, but 1 month ago i updated it proprety with no problems :/

It is fixed, dunno how but last night i tried a lot of things, today i decided to go to PC service but before i tried to install again nvidia, and this time it works. What a beautifull day isn't it, i can smell the spring
