Anoop, these symptoms sound very much like a hardware problem that causes the GPU to sometimes lose contact with the rest of the system. Please make sure your case is free of dust and that the fans are unobstructed, that all connectors are seated firmly, and that your power supply has a sufficiently high power rating. If you still experience the problem, please try running nvidia-settings and selecting the "Thermal Settings" tab to monitor the GPU temperature to see whether it's unreasonably high when the errors occur. Finally, if you have a different GPU you could try in the same system, you could tell if the one you're using is simply damaged. Moving the GPU to a different slot, if one is available, might also help.
