Acer aspire 5750g gpu problem

[IneedanewPC]

I get the message "The NVIDIA GeForce GT 540M device is not removable and cannot be ejected or unplugged."When I play games, I click ok, close the game with the task manager, sometimes after about 15-20 seconds the pc freezes if not if i check in device manager the nvidia gpu has dissapeared and when i try to open ncidia control panel it says compatible hardware isn't found. After a restart everything goes back to normal. Any suggestions as to how I may fix the issue will be very much appreciated .
