Nvidia Optimus GT 555M Graphic Card Dissapeard from Device Manager!

Hi there i have been having trouble with my Graphics card lately and here is how it started:

I was playing SC2 the other day and then suddenly my screen froze i had to press the on/off button for 5 sec to restart. after restarting everything was fine i havnt played games after tht for about 2 - 3 then a few days later i decided to play BF3 and noticed it that the graphics were really low and it was just a huge lag-fest, so i quit the game, went to device manager and under Graphic card tab i found only my Intel HD 3000 and my Nvidia Dissapeared. so i tried going to the Nvidia Settings and it told me its no longer available and that No nvidia graphic card has been found in my system and ive tried downloading latest driver fom nvidia and everytime it scans for compatibility it says: no hardware compatible. ive searched literally days for an answer and could not come up with a solution for this develish problem. i wanted to reinstall my OS and i remembered i left my CD with my brother. i tried running Microsoft Windows fix it from the internet under hardware/device and it says: Hardware changes was probably not detected .
plus i done all the searching and stumbled upon the police virus SCHNITZEL! i got rid of it under safe mode and malwarebytes but now i have run DLL problem or virus. so thats the large picture of my Dilemma! so please anyone out there who could help me out of this huge problem, i would be very greatful and happy.

P.S. i tried uninstalling and reinstalling updating my Intel HD graphic card and to no avail, from the forums i read i should overheat my laptop so that maybe the loose part of the graphic card will solder itself backtogether and im thingking of doing it but im not sure its safe to do.

Problem fixed i reinstalled windows 7 again and still no nvidia then i opened my laptop and cleaned the rubber type area between the heatsinc of the nvidia chip and processor chip with alcohol and bought new heatsinc compound and paste it on the surfaces of the chips and put the laptop backtogether again and it detected a unknown graphic card so i installed the driver of nvidia and it worked. tc and GB i hope this will help people in the future same thing i did with my Xbox 360 before and it workd.
