Hi Sir,I am Bharath From India.I have got the Same problem in my Geforce 210.I can tell you how I fixed That.I Hope it works for you and fixes your problem.
NOTE-Your GPU must have all those wired connected Properly to the Motherboard
1) Download Driver Booster Free from iObit and Install them (You can make it PRO by learning in Youtube)
2) At first Open,It will automatically scan for Outdated Drivers
3) After Searching,It will show the Results and All you have to do is tap 'Update'
What it basically does is find Missing and Out-dated drivers and install it without any Hassle.It actually will mod some Coding inside those Driver Files.
After all these,Please restart your PC and It must work Perfect.If My solution fixes your Problem,Please don't forget to make mine as your Best Answer.Thank you
