Serious GPU problem - Need Help

I recently got some problems regarding my GPU in my laptop, Sorry if my english is bad but I'll try to explain.

After the latest windows update my GPU doesn't work at all. my pc won't detect it nor am I able to open the nvidia controllpanel or install any drivers.

I have a GT540M in my laptop which worked perfectly fine before the latest windows update.

when I try to run the Nvidia controllpanel I get this error: Error: unable to start, No screen connected to the GPU.



Try to reinstall the latest drivers.

how? (yes, my knowledge about this is equal to a potato)

Try If that doesn't work, try driver sweeper and that reinstalling it.
